E-Compressor Motor Controller is an all-in-one solution developed to control the operation of E-Compressor used for air-conditioning of PHEV/EV.

As a built-in type(integrated with the device), it achieved the control circuit optimization

CAN / PWM communication and diagnostic capabilities are provided.

It applies algorithm for precise control of position/speed without motor position sensor(high efficiency, low noise).

The logic ensuring high reliability is implemented.

The IGBT module of iA Group company was adopted.

• - Thermal properties
• - Simplified IGBT assembly process
• - The simplified Middle Cover Hole processing increased the freedom of mechanism design.
• - IGBT Module Package increased space utilization
