Abstract: The designed new kind of high voltage and large power bidirectional DC/DC converter made great improvement on the topological structure of traditional symmetry full-bridge bidirectional DC/DC converter. This paper analyzed the working principle of dual full-bridge bidirectional DC/DC converter with insulated direct current capacitance and active clamping circuit, completing the design calculation of the primary device parameters and optimizing the design of high frequency transformer. The experimental results show that the converter raises the overall efficiency effectively and reduces the volume of the whole machine, with very good stability. 
Key words: bidirectional DC/DC converter; insulated direct current capacitance; active clamping circuit
