Traction Inverters

Traction Inverter IconIn the high-voltage electrical system of a car, truck or bus, the traction inverter sits between the high voltage system battery and the electric motor. It converts the HV system DC voltage into 3 AC output phases to drive the motor.

The combination of the inverter and motor is a key component in an EV, determining the performance, driving feel and dynamics. The range of a vehicle is directly related to the efficiency of the traction inverter and motor across the driving profile, including acceleration, steady state and energy recovery into the battery via regenerative braking.

Power Integrations offers automotive qualified gate drivers and power supply ICs for the traction inverter which increase efficiency while saving space and cost and meeting functional safety. Reinforced isolation, extended creepage distance packages meet latest requirements for vehicles moving to 800 V architectures.
