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.

Sustainability Realized by PEoE

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.

4. More Electric Power by Renewables

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.

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.

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.
