FUTURE HEV/EV  INCREASE ELECTRICAL ANGLE VELOCITY

▪ Increased RPM level will be

required for full HEV and PHEV/EV in future to achieve

smaller form factors of xEV

components, like the e-motor

▪ Higher RPMs require high

speed processing as the Inverter control feedback cycle becomes shorter

Base Function

A key analog component associated with the controller in these HV traction motor systems is an isolated HV

gate driver (HV GDU). HV GDUs connected to the controller drives the power switches such as IGBTs. They convert PWM signals from the controller into gate pulses for the power switches to turn and off.
