摘要
A fixed-frequency pulse width modulation (PWM) controlled bidirectional current-fed series-resonant converter is proposed in this paper. The proposed bidirectional resonant converter is derived based on integration of a bidirectional boost/buck converter and a dual-active-bridge series-resonant converter. The most attractive feature of the proposed bidirectional resonant converter is that its voltage gain is only determined by the duty cycle of primary-side switches and has nothing to do with the transferred power. Therefore, the direction and amplitude of the transferred power can be easily regulated continuously and smoothly. In addition, with the help of an auxiliary inductor, zero voltage switching can be achieved for all the active switches on both primary and secondary sides within the entire operation range. Furthermore, the converter is suitable for wide voltage applications because its voltage gain can be regulated in a wide range. The operational principles and characteristics of the proposed bidirectional resonant converter are analyzed in detail. The feasibility and effectiveness of the proposed converter are fully verified by the experimental results from a 1.6 kW prototype.
