The invention discloses a device for realizing non-fire return of a
train by adopting a bidirectional charger and a control method of device. The device comprises an input conversion unit, an intermediate
direct current unit, a traction
inverter unit, an auxiliary
inverter unit, a bidirectional charger, a motor and a
power storage device, wherein the input conversion unit is used for supplying power for the traction
inverter unit and the auxiliary inverter unit; the intermediate
direct current unit is used for storage and release of
electric energy of a circuit; the traction inverter unit is used for supplying power for the auxiliary inverter unit; the auxiliary inverter unit is used for assisting a load for supplying power, supplying power for the bidirectional charger at the same time and providing excitation for the motor; the bidirectional charger is used for supplying power for the
power storage device and providing input energy for the auxiliary inverter unit; the motor is used for assisting a load for supplying energy; and the
power storage device is used for receiving the charging of the bidirectional charger and storing energy when the
train runs normally or after a non-fire return intermediate
voltage is established, wherein the in non-fire return establishment process, the output
direct current voltage passes through the bidirectional charger to be inversely converted into an
alternating current voltage to release energy. According to the device, non-fire return is realized based on the bidirectional charger, and additional equipment is not added.
