Abstract

A power conversion system includes a filter unit, a DC/DC converter, a DC link, an inverter, a control unit, and a traction motor. The DC/DC converter is used for boosting DC voltage of a DC source and electrically coupled to the DC source through the filter unit. The DC/DC converter includes multiple SiC MOSFETs configured in a synchronous rectification mode by channel reverse conduction control. The inverter is used for converting the boosted DC voltage from the converter to multi-phase AC voltage through the DC link. The control unit is used for providing PWM commands to the converter and the inverter, to convert the DC voltage to AC voltage configured to drive an AC driven device.
