An inverter is used to convert DC power to the AC power used in an electric vehicle motor. The Renesas xEV inverter solution maximizes the HEV/EV motor performance by motor parameter calibration tool and practical inverter hardware designs using a combination of microcontrollers, power management ICs, gate driver ICs, insulated gate bipolar transistors (IGBTs), and fast recovery diodes (FRD).
