Zusammenfassung:	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. Further, the inverter, according to the voltage and current values acquired at the input end, calculates and sends a current actual demanded power to the energy management module, the energy management module, according to the current available power of a supercapacitor, calculates a required output power and sends a command of the required output power to a rectifier, and the rectifier, according to the command of the energy management module, controls the internal electric power pack to output corresponding power. The system is simple in structure and reliable in control, and can increase the dynamic performance of the train and improve the transportation capability of the train. A hybrid power supply method for a diesel multiple unit is also disclosed.
