Bidirectional CLLC resonant converter is one important topology of bidirectional DC/DC converter, it has the advantages of wide frequency range, large voltage regulation range and high power density. Herein, the existing research results of bidirectional CLLC resonant converter were summarized from the aspects of basic topology and working principle, modeling analysis method, control strategy and application. The existing problems were analyzed and the future research emphases were put forwarded. Conclusion showed that the bidirectional CLLC resonant converter was still in the stage of key technology research and small capacity prototype test, and it has a broad application prospect in the field of energy storage and is an important development direction of the high-voltage and large-capacity bidirectional converter topology.
