Title:
ELECTRIC MOTOR DRIVING SYSTEM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/232975
Kind Code:
A1
Abstract:
An electric motor driving system and a vehicle, which relate to the technical field of vehicle control and can simplify the structure of the electric motor driving system and reduce costs. The electric motor driving system comprises a bidirectional charger, an excitation driving assembly and an electric motor controller, wherein the bidirectional charger comprises a power factor correction circuit, a first voltage conversion circuit, a first transformer and a second voltage conversion circuit; a power storage unit is electrically connected to a second port of the second voltage conversion circuit; the excitation driving assembly is electrically connected to a multiplexing node by means of a first switch unit; the multiplexing node is located between the power factor correction circuit and the first voltage conversion circuit; and the excitation driving assembly is used for driving an excitation electric motor.
