Abstract The phase-shifted full-bridge zero voltage switching (ZVS) DC-DC converter is widely adopted in industry applications. But it has some shortcomings, such as narrow ZVS range, excessive duty cycle loss, severe parasitic oscillation, and large circulating loss and so on. Some improved methods were proposed to solve such shortcomings. In this paper, several auxiliary networks were classified hence the key performances of these topologies were analyzed and compared. Moreover, a new auxiliary network was proposed, combined with adaptive network and parallel passive auxiliary network. And then, the prototype of the proposed converter was built. Finally, the advantages and disadvantages of these auxiliary networks were summarized.

Key words： Zero voltage switching full-bridge converter topology comparison auxiliary network
