DRIVING SYSTEM OF MOTOR, POWER SYSTEM AND ELECTRIC VEHICLE

WIPO Patent Application WO/2021/163864

A1

The present application relates to the technical field of power electronics, and provided thereby are a driving system of a motor, power system and electric vehicle. The driving system is used to drive a motor that uses a power battery pack as a power source, the power battery pack comprising at least two mutually independent battery modules; and the driving system comprises: at least two direct current-alternating current (DC-AC) circuits, the battery modules corresponding one to one to the DC-AC circuits. Each battery module is correspondingly connected to an input terminal of one DC-AC circuit, and an output terminal of each DC-AC circuit is connected to a corresponding winding of the motor; and the DC-AC circuits are used to convert the direct current provided by a corresponding battery module into an alternating current, so as to drive the corresponding winding of the motor. Using the driving system, when a battery module fails, the normal power supply of other battery modules will not be affected, and the other battery modules normally supplying power may continue to supply power to a corresponding winding of the motor, such that a vehicle may continue to drive.
