  • Patent number: 11034367
    Abstract: There are provided a power supply system for a diesel multiple-unit train, a diesel multiple-unit train including the power supply system, and a traction control method for a diesel multiple-unit train. The power supply system includes: a diesel power pack, a traction inverter connected to a traction motor, and an auxiliary inverter connected to a train load. The power supply system further includes a direct current chopper and a supercapacitor. A high-voltage side of the direct current chopper is connected to the diesel power pack, and a low-voltage side of the direct current chopper is connected to the supercapacitor. The supercapacitor is connected to the traction inverter and the train load.

  • Publication number: 20200385034
    Abstract: A hybrid power supply system of diesel multiple unit is disclosed. When a train is running, an energy management module sends a level signal of a master controller of the train to an inverter, and the inverter, according to the received level signal of the master controller and the dynamic performance of the hybrid power supply system, sets an envelope curve of train speed vs. traction force and an envelope curve of train speed vs. regenerative braking force to control a traction motor to output the corresponding torque.
