US 2024/0266985 A1 · POWER INTEGRATED MODULE AND MOTOR CONTROL SYSTEM

Abstract

A power integrated module (PIM) and a motor control system are provided. The PIM is adapted to drive a motor. The PIM includes a first transformation circuit, a second transformation circuit, and a plurality of shunt units. The first transformation circuit includes a plurality of first half-bridge circuits, and a coupling relationship among the first half-bridge circuits is selected, so that the first transformation circuit is operated in a rectifier mode or an inverter mode. The second transformation circuit includes a plurality of second half-bridge circuits coupled to the motor. The shunt units are respectively coupled between the second half-bridge circuits and the motor and configured to sense a current between the second transformation circuit and the motor.
