摘要

Provided is a megawatt-level direct-drive permanent magnet electric drive system for electric locomotive, comprising: a first precharging module, a second precharging module, a first four-quadrant rectifier, a second four-quadrant rectifier, a first chopping module, a second chopping module, an intermediate DC circuit, a first inverter module, a second inverter module, a third inverter module and an auxiliary converter. The system can control the direct-drive permanent magnet synchronous motor in electric locomotive using high-power direct-drive permanent magnet synchronous motor, filling the gap in the application of high-power direct-drive permanent magnet synchronous motor in electric locomotive.
