Year

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

Renesas is providing system control solutions to achieve high speed RPM cost down due to smaller system components

Product roadmap

HV GDU - R2A25110KSP -
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.
