TMEIC foresees the world of PEoE, Power Electronics on Everything.
The power electronics is integrated into everything these days and on the way
to digitalization. Then, in near future, power electronics will efficiently function
by linking each other through the digital information/communication systems.
PEoE will further contribute to the sustainable society with more power from
renewables, more stable power to digitalized world and more energy savings
in industries.

Contribution to the Earth by Power Electronics
Activities for CO2 reduction are one of emerging issues. The reduction
policies are now enhanced further than they were.
End-use efficiency (energy saving) and renewables are expected to
play the most important roles in CO2 abatement.

PV Inverter – Overview
The Inverters convert the DC power from the PV panels to the AC power. As the PV
plants increase their capacity, the DC circuits is designed with higher voltage and
larger power output.
As the generation share of PV plants increases in the AC power network, the
Inverters now start playing important roles such like to stabilize the distribution line
voltage.

As the generation share of renewables increases in AC power networks, the power
frequency variation increases due to power variation increase from renewables.
Energy Storage Systems (ESSs) are promoted to stabilize the frequency by
absorbing the power variation.

Large-capacity UPSs of 1000kVA range are available responding to
data center power capacity increase.
Higher reliability can be realized by redundant system configuration
with plural UPSs connected in series or in parallel. Even one of UPSs
is failed, the redundant system continues to provide the power.

6. More Energy Savings in Industries
In industries, many motors working and consuming much power.
For small motors, general inverters are available and contributing
energy saving very much.
For large motors, high voltage rating is better for energy saving.
The combination of high voltage motor and drive will contribute to
extend the energy savings in large machines in industries.
Advanced technologies for high voltage inverters ... TMEIC features
Medium voltage drive inverters with advanced technologies,
already made in India and used in India
Extra-large drive inverters for replacing gas turbine drives

The large-capacity motors are widely used in industrial plants. The drive system
reduces motor power consumption drastically. The combination of large-capacity
motor & drive is applied to the applications, especially as listed below.
Motor and Drive – Overview
The motors are used for various applications, like pumps,
fans, compressors.
For large capacity applications, the high voltage motors offer
high efficiency since they operate with small current.
Further to expand energy savings in high voltage motors,
high voltage inverters are essential.

Energy savings by adjustable speed drive technology
Adjustable speed drive can control the air flow by adjusting the fan rotation speed.
The damper elimination leads to smaller pressure drop and results in smaller
power consumption by the motor.
