Abstract A new method for the current ripple reduction of a three-phase interleaved bidirectional DC-DC converter is proposed. The converter used in this study operates in discontinuous mode to minimize the switching losses. All the switches are turned on at ZVS and ZCS conditions, and turned off at ZVS condition. The charging and discharging power of the battery is controlled by varying the switching frequency while maintaining the discontinuous mode operation. A 3 kW 20 kHz power converter is designed and implemented. Simulation and experimental results show the validity of the proposed method. The proposed control method can be used to reduce the battery ripple current significantly.
