摘要：
In view of the problem of high hack-flow power and high system loss in a bidirectional full-bridge DC-DC converter with a voltage matching ratio of less than 1. In this paper, the LCC compound resonant bidirectional full-bridge DC-DC converter based on phase-shift control is studied. tinder this control strategy, the primary- and secondary side switches of the converter can be United on at zero voltage, and the characteristics of the LCC resonant circuit are utilized. It is beneficial to reduce the converter's hack-flow power and thus reduce the converter's loss. The principle of LCC compound resonant bidirectional converter under phase-shift control is described in detail, and the soft switching conditions and backflow power characteristics of the circuit are analyzed in detail. Finally, the correctness of the theoretical analysis and the feasibility of the circuit scheme arc proved by experimental results.
