HIGH-POWER DIRECT-DRIVE PERMANENT MAGNET ELECTRIC TRANSMISSION SYSTEM FOR ELECTRIC LOCOMOTIVE

WIPO Patent Application WO/2020/093465

A1

A high-power direct-drive permanent magnet electric transmission system for an electric locomotive, comprising: a first four-quadrant rectifier, a second four-quadrant rectifier, an intermediate direct current circuit, a first inverter module, a second inverter module, a third inverter module and an auxiliary converter, wherein the first four-quadrant rectifier and the second four-quadrant rectifier are each connected to a main transformer and the intermediate direct current circuit of the electric locomotive, and the intermediate direct current circuit is separately connected to the first inverter module, the second inverter module, the third inverter module and the auxiliary converter. The present transmission system may control a direct-drive permanent magnet synchronous motor in an electric locomotive using a high-power direct-drive permanent magnet synchronous motor, which fills in a gap in the application of a direct-drive permanent magnet synchronous motor in an electric locomotive.
