Abstract :
This paper proposes a new soft switching bi-directional DC-DC converter. The described converter employs the symmetric topology with high frequency transformer. It gets soft switching with the designed pulse-width modulation control, which guarantees soft switching in wide load range without any additional circuit components. Operation principle and the ZVS condition of the proposed converter are also analyzed. Inductors L1 and L2 are proven to have effect on the ZVS condition. Therefore, the parameter design is taken into account to ensure the soft switching. Furthermore, simplified method to calculate the inductor´s value is also introduced. Besides, the theoretical calculation, analysis and experimental results obtained from a 500 W prototype are also presented, which substantiates the design consideration
