• PSFB example sim and code gen overview

• Overview of code generation

• Overview of PSIM

DCDC 300W 12V Mode2 level 3

PSIM has examples for PSFB with three modes:

- Passive secondary

- Active secondary with overlapping conduction

- Active secondary with “pulse conduction”

These are verified to work with this TI reference design:https://www.ti.com/tool/TIDM-BIDIR-400-12

Basic PWM control

PWM timer defines which GPIO you will use

Other settings are straight forward

Carrier wave type is the tricky one- Triangular (start high or low)- Sawtooth (start high or low)

Start low means ‘B’ is on firstStart high means ‘A’ is on first

More Advanced – Output mode

Options to:- Set/Reset/Toggle at peak or valley of the

carrier wave (Sawtooth or Triangle)- Set high or low based on input to the A or

B and the carrier wave definition- Different settings for the A or B output- Or don’t use this setting

More Advanced – Trip Source

Options to:- Clear/Set/Toggle- On ‘Up’ and/or ‘Down’ of carrier

A ‘Trip Source’ going high is used as the “trigger”

Sawtooth – no Down

Triangle – 50% up 50% down

One can phase shift!

UP

More Advanced – Trip Source

T1 Source and T2 Source ca be any of these

How these “signals” get formed is the interesting bit

PWM Tripzone element – Trip source definition

These are the same signals from the previous slide

One shot means it only runs onceCycle by Cycle is every PWM period

PWM Tripzone element – The DCA event

The DCAH and the DCAL sources can be a wide range of Tripzone signals – these signals will be defined by the X-Bar

You can pick single signalsOr select logical combinations to from the DCAH or DCL source

PWM Tripzone element – The DCA event

DCAEVT1 – one shotDCAEVT2 – cycle by cycle

Are further defined by DCAH or DCAL going:- High- Low- Source1 low & Source 2

high

We do not have arbitrary logic, it can only be ‘1 low’ & ‘2 high’If you need something else you need to invert a signal somewhere else (lots of places to do this)

PWM Tripzone element – Basic Summary

These are used in the PWM elementTo set/reset/toggle the PWM output on the Up or down of the carrierThese settings are in the PWM generator element

The DCAEVT1 or DCAEVT2, etc. signals are defined by the TZ(1) etc. signals going high or low as defined by the logic used.

The X-BAR - Defining TZ(1) et al.

TZ1, TZ2, TZ3 can be defined as the output from a GPIO

If a GPIO is a PWM output then that waveform will be the TZ1 signal

This is an internal connection you do not need to wire something up externally

We are not going to cover xint, cap settings.

PWM X-Bar Element – Define Trip4, 5, 7 et al.

Trip 4, 5, 7, 8, 9, 10, 11, 12 can be defined from a variety of other signals

CMPSS – this is the onboard analog comparator, there are 8 of them. Use this to do Peak current control

Each “MUX” option has different signal origin options.

Comparator Usage to generate a trip signal

A and B outputs can have analog signals mapped

Pins are linked to the A/B and the comparator to be used

Can sync to a PWM timer (needed for PCMC)

The DAC can be linked to the B input, and a slope sync’d with the PWM timer can be injected. Use this for peak current control!!

Top level settings for PCMC – analog trigger of PWM

Iref is an internal variable -> DAC injects slope- > links to Comparator 1 -> Compared with current feedback -> defines trip 4 -> used to make DCAEVT2 when T4 goes high -> PWM turns on a start of sawtooth and switches off when DCAEVT2 goes high

The comparator must sync to the PWM timer and the X-Bar, Tripzone and PWM blocks must all be on the same PWM timer

Top level setup to trigger from another PWM output

Select the GPIO 0 & 1 options to form TZ1 and TZ2 from the X-Bar drop downs (PSIM wire connection is user FYI only.

Use the PWM tripzone to do something with TZ1 & 2

Use the PWM to do something with the DCAEVT2 signal

The PWM Tripzone element must use the same PWM timer as the PWM elementOnly 1 X-Bar per project, but the signals can be used by other PWMs

Hardware and Sim Comparison - Test Hardware

• F28379D controlCARD

• Typhoon HIL 604 (digital oscilloscope function)• HIL System has a bandwidth limitation, switching speeds reduced to 10KHz to

confirm gating logic

• PicoScope 2- channel Oscilloscope• After overall gating logic confirmed at low speed, Scope was used with

100kHz switching to confirm stability of pulses

Phase Shift Full bridge with Acitve Secondary

QA, QB, QC, QD form the full bridge

QE & QF form the active secondary

Reverse Direction setup for PSFB with active secondary

PWM 5A and PWM 6A generate QE and QF which are then used by the X-Bar as TZ1 and TZ2• Run at fsw frequency• Sawtooth start high – means that ‘A’ channel is “ON” with input duty.• PWM6A is phase shifted by 180 degree (-180 OK)• Duty cycle provided by external signal

EPWM Settings QA & QD

QA & QD should form:- QE at duty <0.5- !QF at duty > 0.5

PWM Tripzone setting block is used to generate trip events from QE & QF to control QA & QD

DCA and DCB Event usage for QA & QD -Analysis

DCA_EVENT Source 1 low (QF) & Source 2 High QE- SET on UP portion of tri

DCB_EVENT Source 1 low (QE)- CLEAR on UP portion of tri

Reset at peak (tri)- Not needed signal always low

DCA_EVENT Source 1 low (QF) & Source 2 High QE- SET on UP portion of tri

DCB_EVENT Source 1 low (QE)- CLEAR on UP portion of tri- Not used occurs on “down”

Reset at peak (tri)- QF Always goes high at tri Peak, due to 180 phase

shift from QE

EPWM Settings QB & QC

QB & QC should form:- QF at duty <0.5- !QE at duty > 0.5

PWM Tripzone setting block is used to generate trip events from QE & QF to control QB & QC

DCA and DCB Event usage for QB & QC -Analysis

DCA_EVENT Source 1 low (QE) & Source 2 High QF- SET on DOWN portion of tri

DCB_EVENT Source 1 low (QF)- CLEAR on DOWN portion of tri

Reset at Valley (tri)- Not needed signal always low

DCA_EVENT Source 1 low (QE) & Source 2 High QF- SET on DOWN portion of tri

DCB_EVENT Source 1 low (QF)- CLEAR on DOWN portion of tri- Occurs on UP

ADC, CAN, SPI, SCI, PWM trip zones, Encoder, Up Down Counter, Capture supported for all processors

How Code is Generated

• The Control bit (green traces) is converted into code

• The ADC and PWM elements define the pins and register setup for a particular “feature”

• The algorithm is converted to C code

• Interrupt routines are generated based on the digital execution rate

Variables are Linked to Schematic Elements

Variables in the code are derived from element names in PSIM

Interrupt Routine Generation

In this example there are 4 code execution rates: 20k, 2k, 200, 20No PWMs are used, so only 2 interrupts are timer basedThere are only 2 timers!The longer interrupts are function based

Peripheral Setup is “Drop Down Menu”

• The supported settings for a particular hardware feature are available via drop down menu

• Trip zone setup, Trip actions, ADC triggering, HRPWM, etc.

• These features are device specific.

• Some features are not supported by code gen (X-bar only supported on F2837x, F28004x)

C code injection – with C block

• Use the C block

• Code can be inserted into a:• Interrupt routine

• Initialization function

• Variable definition

• Macro

• From external C files

What is Generated?

• A full CCS (Code Composer Studio) project is generated

• All necessary header files for TI DMC library elements are included

• Simply import the *.pjt file

PSFB PWM GenerationPhase Shift Full bridge with active secondary and Peak Current Control requires the use of the:

- X Bar

- Comparator triggers

- DAC with slope compensation

- Event triggering from PMWs that trigger other PWMs

The next 20 slides go into detail about how the settings are chosen to accomplish this in the example simulations in PSIM examples

PSIM User Feedback

• Easy to use

• Robust

• Stable

• Lots of tutorial resources

• Helpful support staff

• Affordable

• Accurate

PSIM Capabilities

• Analog control

• Digital control (z-domain)

• Ideal & non-ideal switches

• Thermal - switching and conduction loss

• Motor and mechanical models• Advanced non-linear and links to

FEA tool (JMAG)

• Runtime C-compiler & DLL link

• Co-sim with Simulink

• Link to LTspice

• Embedded code generation • TI C2000 or generic c-code

• Co-simulate with modelsim• Verilog and VHDL code verification

• Switch mode AC sweeps

• Scripting for simulation automation

Switchmode AC Sweep

• PSIM runs time domain simulations with target perturbation frequencies

• Almost “any” topology can be swept

• No average models – no extra math

• Similar method to benchtop equipment

PSIM Switch ModelsModel type Applications

Ideal Switch (PSIM) – behavioral simulations 80-90% of all simulations

- Frequency sweeps- Control design- Digital control- Component sizing (L & C)- System level simulation

Level 2 Switch (PSIM) - Switching transient analysis- Gate drive- Digital control- Systems level with “details”

Thermal Switch (PSIM) - Loss estimation (switching & conduction)- Junction temperature estimation- Heatsink requirements

SPICE - Manufactures SPICE model- Gate drive- Switching transient analysis

The Problem With a “Real Switch” Sim

• Simulation of Wolfspeed -C2M0280120D1 - PSIM

• On->Off Transition ~16ns• Accurate resolution takes 1ns or

smaller timestep

• Converter steady state is likely several hundred switching cycles

• Will cause a very long simulation time.

Thermal Model – Ideal Switch

• Thermal model use an ideal switch – drastically reduces the computation points

• 200kHz switching; 60 cycles to steady state – SiC from last slide 15ns transition

Level 2 - “Real Switch” Thermal (ideal)

1ns Timestep 50 pts/cycle = 1/(200k*50) = 100ns timestep

60 cycles @ 200kHz = 300us1ns timestep = 300k calculations

60 cycles @ 200kHz = 300us100ns timestep = 3k calculations

Heatsink Thermal Parameters

• We need thermal resistance with airflow, coolant, natural convection, etc.

• Mass and material composition

Heatsink Thermal Equivalent

Resistors – thermal impedance 0C/W

Capacitors – Thermal mass J/(0C*Kg)

Data Extraction

• R Theta comes from the figure or use the 100 CFM value

• Thermal mass is Mass (Kg)* Heat capacity• Careful as specific heat units can

vary kJ/(Kg*0C), J/(Kg*0C), J/(mol*0C) it is very easy to be off by a few orders of magnitude.

• 2.019 * 910 (Al) = 1837 <- heavy heatsinks will have very large capacities.

Thermal Models

• MOSFET (Eon) is for SiC & GaNallows for 3rd quadrant curve definition

• Switching and conduction losses are internally calculated

• Causer or Foster Tj -> case thermal network is internally defined

Device Database – Datasheet Information

• Use the import tool to easily import datasheet figures• Curves for different temps

• Conduction loss

• Switching loss

• Body diode

• Define Cauer/Foster thermal network

Thermal Inductor Model

• Core and winding losses dependant on:• Core material

• Mechanical winding characteristics

• Winding material – wire, strip, litz

• Winding distribution

• Core shape

• Air gap

• Provides core and winding loss

• The DSIM solver is revolutionary – it is 10x – 1000x faster than any other simulator on the market

• Simulate simple inverters or microgrids with thousands of active switches.

• Simulate a realistic switch transition with minimal impact on simulation speed is unique.

• Simulations speeds are 5-6x slower opposed an exponential increase with other tools

• DSIM is extremely robust with virtually no convergence problem.
