Abstract

A motor control circuit includes a first switch module, a three-phase inverter, and a control module. A power supply module, the first switch module, the three-phase inverter, and a three-phase alternating current motor form a current loop; midpoints of three phase legs of the three-phase inverter are respectively connected to three phase coils of the three-phase alternating current motor; the three-phase alternating current motor is configured to input or output a current by using a wire N extending from a connection point of the three phase coils; the control module is connected to the three-phase inverter, first switch module, three-phase alternating current motor, and power supply module; the control module is configured to control the three-phase inverter to enable the motor control circuit to receive a voltage of the power supply module and output a direct current, and to boost a voltage of the power supply module.
