President�s MessageMy sincerest wishes to all of you for a

joyful and prosperous new year!! As PELSPresident, 2001 was an exciting and enjoy-able time for me. I was fortunate to attendthe three major PELS conferences, PESC,APEC, and INTELEC. Each of them doesan outstanding job of serving our member-ship in their own unique way. Our confer-ences have evolved into multifaceted meet-ings wherein attendees are not only able to

attend technical papersessions and tutorials,but can also view indus-trial exhibits, networkand attend social func-tions, visit local indus-tries, and participate inorganizational and

technical committee meetings. I had thepleasure of attending INTELEC this year forthe first time. PELS can take great pride inthis exemplary event in telecom energy sys-tems. It has a first-rate exhibition, a dynamicorganizing committee, and a high level ofindustry support and participation. If youare among the roughly half of our membersthat occasionally or never attend a confer-ence, I strongly encourage you to check oneout and take advantage of the benefits.

Thanks to the hard work of editor-in-chief, Art Kelley, the Transactions hasmoved to completely electronic review andcorrespondence, while maintaining its veryhigh quality level. Our system for handlingand reviewing papers is now as good as anyin the IEEE. Our website has also been re-cently overhauled under the direction of ourwebmaster, Phil Krein. Of particular note,we now have a �PELS Answers� group.Anyone can send a question in the generalarea of power electronics toanswers@pels.org, and this team of volun-teers will try to provide the information youneed. Any suggestions on further improve-ments to our website and its services areappreciated.

PELS has taken several strides to im-prove educational services and opportuni-ties for our members during the past year.As you a probably aware from past articlesin this publication, the �Future Energy Chal-lenge� completed its inaugural competitionin October. This student event is a great

APEC® Returns to DallasThe Applied Power Electronics Confer-

ence (APEC) will be returning to the AdamsMark Hotel in Dallas, TX. The conferencestarts Sunday, March 10, with professionaleducation seminars and concludes Thursday,March 14.

APEC is like a family. For sixteen con-secutive years in good times and bad, wehave participated in APEC. We come to-gether once each year with a single goal�to share our research, experience and knowl-edge of �applied power electronics.� Thisyear authors from 25 countries will presentpapers at APEC, andforty-five percent(45%) of these papersare from colleaguesoutside the USA, con-firming that APEC is aninternational Confer-ence.

We were undaunted by �Desert Storm�in 1991, and �El Nino� in 1998, and we willnot let the tragic events of September 11hamper our determination, once again, to puton a world-class program.

Being selected to present a technicalpaper or a Professional Education Seminarat APEC is not easy, as only 50% of all sub-missions are accepted for the Conference.The good news is that APEC has a long listof capable experts who can offer the high-est caliber of applied power electronics edu-cation for every attendee.

Over 180 papers will be presented in26 technical sessions commencing Mondayafternoon. Sessions for APEC 2002 willinclude papers on dc/dc converters, manu-facturing, marketing, motor drives, EMI,PFC, VRM�s, lamp ballast�s, utility inter-face, UPS, modeling and simulation to rec-

Australia to Host PESC®

The 2002 Power Electronics Special-ists Conference (PESC) will be held June23 � 27, 2002, in Cairns, in tropical farnorth Queensland, Australia. As stated in[1], �Cairns is the tourist �capital� of the FarNorth and one of Australia�s top travellers�destinations. From Cairns, you can arrangetrips to the Great Barrier Reef, Green Islandand Fitzroy Island, the beautiful AthertonTableland, the market town of Kuranda, thestring of enchanting beaches stretching50km (30mi) north to Port Douglas, and thespectacular rainforest and coastal scenery ofCape Tribulation and the Daintree River.�

Just over a year agoI visited Cairns andworked with GrahameHolmes, ProgramChair, his wife Sophiewho has lots of experi-ence and enthusiasm,and their two childrenwho proved to be excellent connoisseurs ofall things to do with tourism, hotels, attrac-tions etc. They were there on holiday, butwe worked very solidly for nearly 24 hours,digging under the surface. I hadn�t been toCairns since 1993 when I attended the Aus-tralian National Engineering conference.That was when I decided that Cairns was anexcellent place for a conference, and when

Become an IEEE SeniorMember

The Power Electronics Society is con-ducting a Senior Member drive to nominatenew IEEE Senior Members from our Soci-ety. Some of the benefits of Senior Mem-bership are:� The professional recognition of yourpeers for technical and professional excel-lence.� An attractive fine wood and bronze en-graved Senior Member plaque to proudlydisplay.� Up to $25 gift certificate toward onenew Society membership.� A letter of commendation to your em-ployer on the achievement of Senior Mem-

ber grade (upon the request of the newlyelected Senior Member.)� Eligibility to hold executive IEEE vol-unteer positions.

The requirements for Senior Member-ship are:� Ten years of professional practice (a BScounts as three years, an MS as four yearsand a PhD as five years).� Five years of significant performance.Many prospective applicants make the mis-take of assuming that �significant perfor-mance� requires special awards, patents orother extremely sophisticated technical ac-complishments; such is not the case. Sig-nificant performance is also indicated bysubstantial job responsibilities, such as be-ing team leader, task supervisor, engineerin charge of a program or project, engineeror scientist performingresearch with somemeasure of success (pa-pers), or faculty devel-oping and teachingcourses with researchand publications.

The applicationprocess is straightforward: just fill out anapplication form (it can be done online). Youwill need three references, who must be Se-nior Members. The advantage of beingsponsored by PELS is that only two refer-ences are then needed. Moreover, we canhelp you find additional references!

Plans for the nextevent are well underway. Other new educa-tional products include tutorials availableon-line and on CD, with more on the way.

PELS membership continues to growat a rate that outpaces the IEEE as a whole.We are continuously adding new chapters,many of which are joint with other societ-ies. Our level of cooperation with our sistersocieties has never been higher. We con-tinue to add regional conferences around theworld to the list of events that we support. Ilook forward to many more exciting oppor-tunities and undertakings for PELS in thecoming year. As always, we need volun-teers like you to make PELS a better orga-nization for all of us.

I first met Intermedia, who ran that confer-ence. I am delighted to report that this largetown / small city has gained in sophistica-tion, but has not lost its energy and vibrancy.Its facilities have dramatically increased, andthe palpable sense of a relaxed, casual,friendly, tropical, small-town environmentwas exactly as I had remembered it.

The Conference will be in a new high-tech convention center [2], of which we willuse only a fraction, but we will be very com-fortable and strongly supported by very goodstaff.

By now there should be a range of rec-ommendations for accommodations on ourweb site [3], all the way down to back-pack-ers for students. The five-star hotel [4] isabout 150 meters from the convention cen-ter and is exactly as you would expect.About another 100 meters further there is alocally-owned, four-star hotel [5], withwhich we were very impressed. They havea range of good economical restaurants forquick lunches, and displayed a real commit-ment to quality. They have a highly com-mitted staff, fiercely proud of the fact thatthey were NOT part of a chain. A lot of careand thought has gone into helping peoplewho are touring and want to control theirexpenditure so that they can splurge else-where. Many more possibilities are nearby,such as a range of apartments for sharing,or for families. Peter Wolfs, in charge ofour audio-visual arrangements, visitedCairns recently and reports very favorablyon a nearby apartment complex [6], one andtwo bedroom apartments, about 18 monthsold, very reasonably priced.

The jewel for anyone who likes abso-lute isolation right on tropical white sandybeaches might be to stay in tiny, specializedbeach resort areas up to 25 km up the coast[7]. You�d need to pick up a car at the air-port, the 25 km drive on mainly rural roadstakes about 25 minutes, and you can parkcurbside at the convention center for free!Might sound a bit indulgent but if the ex-change rate stays roughly where it is ($1AUD = $0.52 US in January), why not?

The social program is shaping up well,and is expanding by the minute. We areworking to get some Australian �flavor� intothe Sunday evening welcoming reception.Many of us enjoyed the short brass concertat PESC in Vancouver. It was challengingto provide a similar experience in Cairns,since the musicians live long distances awayin the main population centers of Australia.

Fortunately, two professional musicians,Vicente Salas and Manuel Gordillo, will beattending PESC in Cairns and have agreedto provide us with about an hour of pianoand flute music on Monday evening, whichwe will follow with refreshments.

Sophie is looking at the day tours foraccompanying persons and the offerings arevast. The surrounding World HeritageTropical Rainforests are within a few kilo-meters of Cairns. The coastal strip supportsintensive sugar cane farming. Only a couplekilometers or so from the sea the land risessteeply 350 meters to tablelands with moretraditional Australian agriculture. An oldrestored train makes the daily run, zigzag-ging through the rain forest and lots of tun-nels up the escarpment to the tablelands.Sophie also plans to exhibit art featuringlocal artists, much of whose work concen-trates on local themes, in the expansive foyerof the convention center. On the outskirtsof town is Tjapukai, a remarkable centerwhere you can learn about aboriginal cul-ture, see shows with actors mixed in with3D laser imaging, see traditional dancing,enjoy Australia Bush Tucker, and so on [8].

We are working with Intermedia, pro-fessional conference organizers based inBrisbane, the capital of Queensland, to en-sure a very high level of professional atten-tion at all levels of the conference organiza-tion. As is usual with PESC, much will bedone by enthusiastic volunteers within theIEEE. However the geographic distancebetween Australian committee members ledus to believe that we should work alongsideonsite professionals to be really sure aboutthe quality of all aspects of the conference.

Since I am currently at the Universityof South Carolina with Jerry Hudgins, I en-listed a long-time friend Gerard Ledwich,Queensland University of Technology, asDeputy General Chair to make sure thatthings were always in order. We are alsosupported by Geoff Walker, a very keenyoung academic at the University ofQueensland in Brisbane, who is the activeliaison between our committee andIntermedia.

The conference ends on Thursdayevening. And then Friday?

One of the most memorable days of mylife, about 10 years ago, was to take a full-day tour of one of the natural wonders ofthe world�the outer Great Barrier Reef [9].Huge aluminum twin-hulled wave-piercingcatamarans carry 250 passengers up thecoast 60 km to Port Douglas, then head out

to sea about 80 km at very high speed to ahuge moored viewing platform on the outerreef, where coral is only a couple feet be-low the surface. You can swim, snorkel,scuba dive, or if you don�t want to get wet,there are underwater viewing rooms, glass-bottomed boats and mini �submarines.� Abuffet luncheon on board the big cat, thenback to the coral and the fish. Late after-noon they roar you back to Cairns. As I re-member I slept most of the way back.

Then you see the rest of Australia.Then you go home.

Tricks of the Trade: Poincare Stability Analysis of Switching Converters with Nonlinear Control©Contributed by Keyue SmedleyUniversity of California, Irvine, USAsmedley@ece.uci.edu

From the slightly nonlinear buck to theseriously nonlinear buckboost, switchingconverters are nonlinear in nature. The bestperformance of a nonlinear system oftencomes from nonlinearcontrol. This articlepresents a trick forstudying the stability ofswitching converterswith nonlinear controlusing Poincare maps[1,2].

Figure 1 illustrates the concept of thePoincare map. Behavior of state variables(inductor currents and capacitor voltages)is plotted, and in this case the motionconverges to the closed orbit γ. We canchoose a local cross section Σ so that thestate motion always transverses Σ. Thestates are sampled every time the motioncrosses Σ. The samples give rise to a newdiscrete-event system, called a Poincaremap, that describes the dynamics fromcrossing to crossing. For most powerconverters, the Poincare map is easier toanalyze than the original system. Also, thestability of the behavior in Σ reflects thestability of the overall system.

Fig. 1. Poincare map development

Let�s use a buck converter with current-mode control (Fig. 2) as an example toexplain the mapping method. In the circuit,the clock turns on the active switch at thebeginning of the switching cycle. Therising inductor current is compared to acurrent reference with a compensationramp. When the comparator changes state,it resets the flip/flop and turns off theswitch.

Fig. 3 shows the time behavior. Thesolid line iL

* represents the steady stateinductor current and the dashed line iLrepresents a transient condition. Theanalysis is well-known [3]. The inductorcurrent has a rising slope M1=(Vg-Vo/L) and

falling slope M2=Vo/L. The compensationramp has a slope of Mc. By equating thedistance from the current reference iref to thevalley of the inductor current at the end ofthe 0th cycle and the beginning of the firstcycle, we get

scscs TdMMTdMTdM 11002 )()1( +=+−(1)

This can be rearranged to map the duty ratiofrom the 0th cycle to the first cycle:

d1 =M 2

M c + M1

+M c − M 2

Mc + M 1

d0 (2)

Similarly, we can map the duty ratio fromthe nth cycle to (n+1)th cycle. In general, aPoincare map can be expressed as dn+1 =f(dn). The equilibrium point of the dutyratio d* can be derived when f(d*)= d*,

map is |µ |<1. For the special case of µ =0,i.e. Mc=M2, the transient recovers in a singlecycle (a dead-beat behavior). The Poincaremap for this one-cycle response is shownin Fig. 4. When | µ |<1, the transient will

converge to the steady state after severalcycles. Fig. 5 illustrates an oscillatoryconvergence of the transient for �1 < µ < 0,while Fig. 6 shows a monotonicallydecaying transient for 0 < µ < 1. The caseµ ≥ 1 requires a flat or rising off-stateinductor current, which will not occur witha load that consumes energy.

the first cycle, then d1 is mapped back to d0in the next cycle and the pattern will repeatforever. When µ <-1, shown in Fig. 8, themap no longer converges. For any initialduty ratio d0 that is not equal to d*, thesubsequent duty ratios diverge to chaos, andthe duty ratio is unstable. If d* is reachedsomehow, noise will perturb the duty ratioenough to continue the chaotic behavior.

Fig. 8. µ <-1, chaotic map

In most applications, we would want tohave -1< µ < 0 or 0 < µ < 1. Fig. 9 showsthe duty ratio for the first 20 cycles withµ = 0.8 and µ = -0.8. In Fig. 10, the numberof cycles required for the transient to decayto 36% (analogous to a time constant) or to5% are shown. One may use the formercurve to estimate the time constant of a cur-rent-mode control loop.

The Poincare map is an effective toolfor nonlinear analysis of switching convert-ers with cycle-by-cycle nonlinear control;e.g., [4]. By establishing the Poincare mapfrom waveforms that determine duty ratio,the stability condition and convergencespeed can be evaluated.

INTELEC �01 RecapThe 2001 International Telecommuni-

cations Energy Conference (INTELEC) tookplace October 14 � 18, 2001 at theEdinburgh International Conference Centre.Representatives from over 35 countries tookpart, with over 1100 people attending theevent, and from the feedback received theConference was viewed as a complete suc-cess.

Three interesting and varied tutorialswere held Sunday afternoon, and the Exhi-bition area was formally opened thatevening by Mr John Parsons, the Chairmanof INTELEC 2001. John�s introductoryspeech majored on the importance of theConference and welcomed everyone toEdinburgh. With over 75 exhibition standsthere were plenty of new technical productson view and exhibitors on hand to discusstheir wares. Battery manufacturers weremuch in evidence as well as remote moni-toring systems and software support sys-tems. For the first time in several years,some Air Handling unit manufacturers were

at the Conference showing their products,as well as Standby Engine manufacturersexplaining the importance of reliable reservepower supplies.

The two opening guest speakers, DrPaul Reynolds (CEO of BT Wholesale) andDr Peter Radley (Chairman of Alcatel UK),set the scene for the Conference on Mon-day morning by explaining the importanceof communications in the 21st century. Fac-tors such as the economic status of the worldand the importance of power were high-lighted. This was a slightly different ap-proach than at previous conferences, wherethe plenary session normally covers techni-cal issues. The theme of both presentationswas that significant changes are taking placein the telecommunications industry, particu-larly with the advent of 3G and other highheat dissipating products. The energy costsare set to increase between 4% and 7% inthe coming years, placing additional costson the operators and additional burdens oncooling equipment design.

Throughout the following 4 days, over

90 technical papers were delivered and whilebattery problems continued to be a majortheme of the conference, there were somevery interesting presentations on users� ex-perience of installing reliable power suppliesin remote locations.

One common theme through many ofthe papers was the need for high reliabilityand the cost of failure. Costs of loss of rev-enue ranged from £8k per minute for a smallexchange to approaching £700k for DataCentres. There was also increased attentionpaid to various forms of fuel cells. While inmany cases their costs were higher than con-ventional standby systems, there was felt tobe a market for them in certain applications.

In a situation where conferences arebeing cancelled as a result of the ongoingimpact of the World Trade Center disasterand the downturn in the world�s economy,the attendance of over 1100 people indicateshow important this Conference is to manypeople around the world.

INTELEC 2002 will be held inMontreal, September 29 � October 3, 2002.

Chapter NewsI would like to begin this year by shar-

ing good news with you about two recentlycreated chapters. One is a PELS/PES/IASjoint chapter at Campina Grande (BahiaSection) in Brazil, which was organized byProf. Edison Cabral da Silva. The other is a

PELS student chapter atCENIDET, Mexico(Morelos Section), andwas organized by CiroNu£ez. A complete listof current PELS regu-lar, joint, and studentchapters can be found at

http://www.pels.org/Comm/Chapters/chapters.html . I would like to express mydeepest wishes for the success of these newchapters.

I would also like to encourage all chap-ters to apply (see form on page 10) for the2001 Best Chapter Award. PELS providesthis award, consisting of a $1,500 USD cashprize and a certificate, to recognize techni-cal activities developed during 2001.

I have observed that many chaptershave excellent, high-level technical activi-ties in their local or regional zone of influ-ence. Those kind of activities can give chap-ters a good chance of winning this impor-tant award.

PESC® 2002:From RAP to PWM

Problem/Wisdom Matching (PWM) isthe process of matching the wisdom of ourcolleagues to a specified problem. Formerlycalled RAP (a term which now has addi-tional unintended connotations) sessions,and briefly Brain Power Groups (good, butjust not catchy enough),PWM sessions will sat-isfy the need to discussand resolve issues ofimportance to powerelectronics profession-als at the 2002 PowerElectronics SpecialistsConference (PESC).

The three topics that most satisfy thefollowing criteria will be chosen:• Of interest to many PESC attendees.• Have sufficient volunteer panelmembers.• Important to the profession.Some topics suggested so far include:1. Reform of the conference and/or journalpaper review format, including:

• Quality control of the process• Reviewer rewards and/orrecognition• Identification of reviewers ashaving �endorsed� the paper• Author appeal process• Should PESC be fully reviewed?• Does the recording of academic (orother) advance need to be betterorganized?• Can we replace �serial� (timebased) publications with �keyword� or�topic� based electronic access?

2. The teaching of power electronics:• �A knowledge of switching devicephysics is useless�?• Sharing of on-line resources

3. Battery and/or energy storagetechnology

• The merits of various technologies• Differing power conversionrequirements

4. Resolving the mismatch betweenacademic pursuits and the needs of industry:

• Selection of research areas• Bridging the gap betweenconceptual ideas and industrial practice• Ensuring there is a practical basisfor research

5. Managing di/dt of low-voltagecapacitors6. EMI/RFI

If you have any ideas for topics youwould like to see discussed, could contrib-ute to topic discussions, or have suggestionsfor potential panel members, please emailLawrence Borle as soon as possible. For

current information, please visit thePESC�02 website at http://www.pesc02.com/

APEC Returns to Dallas from pg 1tifier and control circuits.

In comparing the 15 professional edu-cation seminars in 2002 versus 2001, only 3(teams) from 2001 will once again presentSeminars. This illustrates the depth of ourexperts as well as our commitment to pro-vide new topics of interest. It also showsthat no one is automatically accepted solelydue to his or her credentials or prior partici-pation.

As the emerging 42 volt next-genera-tion automotive electrical power systems aredeployed, we are including a (co-authored)seminar on this topic that will include JohnMiller of Ford Motor Co. In addition, a de-bate on the 42V automotive bus will be oneof our three interactive RAP Sessions beingheld on Tuesday evening. The other pro-fessional education seminars will focus onmotor drives, PFC, dc/dc converters, solar/alternative energy, EMI, packaging and ther-mal management, HALT/HASS, optimizingsemiconductors, and power supply design.

In addition to the 42 volt bus, the othertwo RAP Sessions will deal with ASICS andcontract manufacturing. This is one oppor-tunity whereby the attendee can challengethe experts on the concepts being debated.

Rounding out our program will be 12exhibitor Education Seminars, the 16th an-nual Micro Mouse competition, and theWednesday evening banquet held at theDallas World Aquarium.

We will also have an Exhibition Hallwith up to 148 booths where you can inter-act with factory direct experts on their lat-est product offerings while enjoying ourcatered reception on Monday evening. Adrawing will be conducted Tuesday eveningin the Exhibit Hall, and some lucky attend-ees will carry home a camcorder, digitalcamera, GPS system or a DVD. All win-ners need to be present in the Exhibit Hallto qualify.

For additional information, includingon-line registration, please check www.apec-conf.org or contact the APEC office at+1 202 973 8664.

On behalf of the entire ConferenceCommittee let me express our gratitude foryour prior participation and extend a warmwelcome to APEC 2002. We thank you foryour patronage of the Conference and lookforward to greeting you in Dallas.

On a personal note, this will be my lastAPEC conference, and I would like to seeyou so I can personally extend my bestwishes to each of you.

FEPPCON Projects Future of Power ElectronicsThe fourth IEEE International Work-

shop on The Future of Electronic Power Pro-cessing and Conversion (FEPPCON) washeld May 27 � 29, 2001. This series of work-shops was started in the late 1980�s to ex-plore future developments in our field. Theexperience during the past ten years has con-firmed the need and value of these Work-shops.

This workshop was hosted and spon-sored by the Electrical Machines and PowerElectronics Group of the Department ofElectrical, Electronic and Systems Engineer-ing of the University of Catania, Italy. Itwas held at a new venue on Salina, one ofthe picturesque Eolian Islands north of Sic-ily. A relatively small group from industryand the university brainstormed over whatthe future holds in store. Technological is-sues were discussed on the first day, andapplications on the second day.

The main theme was to identify changesexpected during the next 5 years and tostrategize where we want power electronics

to be by the year 2010. There were two pri-mary objectives: (1) identify key issues andthe real �show stoppers� in power electron-ics technology, and (2).identify the funda-mental limitations and technological prob-lems that must be addressed in power elec-tronics technology.

We attempted to be bold in our projec-tion into the future; otherwise we will endup with the same type of discussions thatwe have at the usual conferences. In ourbold projections, we considered whatpresent constraints that we accept as givenmust be thrown away, because they are tiedto our present way of thinking, manufactur-ing, teaching, designing.

The discussions were fruitful and ledto the following shortened version of work-shop conclusions:� For low-power applications, the integra-tion will continue to the points of minimumcost, driven by the requirements for minia-turization, reliability, and performance.

IEEE Press and WileyCreate Joint ImprintOn December 2, 2000, the IEEE Ex-

ecutive Committee approved a proposal en-abling the IEEE Press to join John Wiley &Sons in a co-branded imprint that will in-clude future titles from both publishers.Under the plan, the IEEE Press will workwith authors to acquire titles, and Wiley willhandle everything else: production, market-ing, warehousing, sales, and order fulfill-ment. Wiley will also contribute its ownelectrical and electronics engineering titlesto the imprint, subject to IEEE review.Books in the co-branded imprint will carrythe logos of both organizations. Each partywill be responsible for its own expenses, andWiley will pay a royalty to the IEEE fromsales of the books in the imprint. Imple-mentation of the plan was completed inApril, 2001.

According to the IEEE Press, the planpresents the opportunity to advance the mis-sion of the IEEE book program, providingessential books for IEEE members at a dis-count and enhancing the image of the IEEEwithin the technical community. At the sametime, the IEEE expects to significantly re-duce the costs of the book program by tak-ing advantage of Wiley�s economies of scalein production and worldwide marketing.The IEEE member benefit of a 15% discountfor IEEE Press books was preserved in thepartnership agreement, and that feature wasextended to Wiley books included in theimprint.

John Wiley & Sons, Inc., was foundedin 1807, and it is a global publisher of printand electronic products. The company spe-cializes in scientific, technical, and medicalbooks and journals; professional and con-sumer books and subscription services; andtextbooks and educational materials for un-dergraduate and graduate students as wellas lifelong learners. The Wiley family re-mains actively involved in the business,which is traded on the NYSE. The IEEEbrings to the partnership its status as theworld�s largest technical professional soci-ety, with more than 360,000 members inapproximately 150 countries. Through thesemembers, the IEEE is a leading authority inall areas of electrical engineering. The IEEEproduces nearly 30 percent of the world�sliterature in the electrical and electronicsengineering and control technology fields.It has created more than 800 active consen-sus standards, and sponsors or cosponsorsmore than 300 technical conferences eachyear.

Those interested in having their workpublished and globally distributed under theWiley/IEEE co-brand should follow theIEEE Press Proposal Guidelines provided onthe Web at http://www.ieee.org/organiza-tions/pubs/press/prpgd.htm. Potential au-thors of books in the field of the Antennasand Propagation Society (AP-S) should alsocontact Robert Mailloux, Chair of the AP-SPress Liaison Committee, AFRL/SNH,Hanscom AFB, MA 01731-2909 USA; Tel:+1 781 377 3710; Fax: +1 781 377 5040; E-mail: Robert.Mailloux@hanscom.af.mil.IEEE Press books can be purchased on theWeb at http://shop.ieee.org/store; note theinstructions for requesting the IEEE mem-ber discount from Wiley.

FEPPCOM Report from page 9� For medium-power applications, thetotal system integration still leaves a lot ofroom for improvements in cost, power mod-ules, control and sensing, passives, reliabil-ity, and performance.� For very high-power applications,modularization will be expanding, providedthe system cost, efficiency, flexibility, andEMC are taken into account.� Fast energy storage is required in nu-merous applications. At present the supercapacitors seem the most promising solu-tion for energies up to 5 kWh. In the nextten years, all other energy storage optionswill continue to be considered.� High ratio of peak/average power rat-ing is important in numerous applicationsand is thermally limited. In order to pushthe limits we need to use active temperaturecontrol, improved electro-thermal CADmodelling, increased thermal capacitance inthe packages, and better power intercon-nects.
