Abstract

A bidirectional DCDC conversion circuit comprises a transformer, a power bus side circuit, a battery side circuit, and a controller. The power bus side circuit and the battery side circuit are respectively connected to the primary and secondary sides of the transformer. The bus side switching transistors synchronously conducts or turns off, and on/off of the battery side switch tube is in reverse phase with on/off of the bus side switch tube, thereby achieving bidirectional operation of battery charging and discharging. Multiple energy storage branches are connected in series or parallel, and output vibration can be effectively reduced through phase offset control. Th econversion circuit is free of an additional balancing circuit, and the balancing capacitor on the power supply side will automatically balance the bus voltage, thereby improving the conversion efficiency of the circuit.
