Title:
MOTOR DRIVE SYSTEM FOR ELECTRIC AUTOMOBILE, PROCESSING METHOD, ELECTRIC VEHICLE, AND VEHICLE HOUSING
Document Type and Number:
WIPO Patent Application WO/2019/144879
Kind Code:
A1
Abstract:
A drive system, relating to the field of power devices. The system comprises: an alternating current motor set, a rectifying component, and direct current motor set connected in sequence. The alternating current motor set comprises at least one alternating current drive motor (a). The direct current motor set comprises at least one direct current drive motor (b). The rectifying component comprises at least one rectifier (17). The rectifier (17) comprises a three-phase input port, a direct current output port, and a direct current input port. The direct current motor set is electrically connected between the direct current output port and the direct current input port. An output port of the alternating current drive motor (a) is connected to the three-phase input port. When the system operates, the electrical energy consumed by the system is delivered, at least in part, between the direct current motor set and the alternating current motor set in different load conditions, thereby simultaneously utilizing properties of the alternating current drive motor (a) and the direct current drive motor (b) and improving the electrical energy utilization of the entire system.
