IGBT

What is IGBT?

Insulated Gate Bipolar Transistor 

IGBTs are a type of transistor in power semiconductor devices and are mainly used as semiconductor switches for switching in inverter circuits for driving motors.

Using ISFIT®, our unique solderless press fit terminal, for IGBT modules can eliminate the conventional soldering process. Furthermore, the ISFIT helps to minimize the risk of damage to the circuit board and improves assembly workability by using lower insertion force than the conventional eye-of-needle type terminal.

What is PCU?

Power Control Unit 

This is used to receive signals from vehicle and controlling IGBT module for power control.

BMS/CMU

What is BMS?   

Battery Management System


What is CMU?

Cell Management Unit 

This is used for measuring and monitoring battery status. Lithium-Ion batteries need to be strictly controlled – this system/unit will shut-off power transmission for any abnormal status.
