The invention belongs to the technical field of power conversion, and relates to a three-phase bidirectional interleaving converter and a control method. The converter comprises filter inductors LA, LB and LC which are respectively connected with three-phase alternating current ends UA, UB and UC; synonym terminals of one ends of the common mode inductors LMA, LMB and LMC are connected with the filter inductors LA, LB and LC; the two T-shaped sub-converters are connected with the other pair of synonym terminals of the common mode inductor to form a parallel structure, and the phase difference of control signals of the two T-shaped sub-converters is 180 degrees; wherein an upper bridge arm and a lower bridge arm of the T-type sub-converter are connected with a direct-current bus, and a middle bridge arm is connected with the common-mode inductor; the capacitor C1 and the capacitor C2 are connected in series on the direct current bus, and the middle bridge arm is connected to the middle point of the capacitor C1 and the capacitor C2. Phase-shift control is introduced into the two sub-converters, the two staggered sub-converters can reduce input or output current ripples, and the common-mode inductor reduces circulating current between the two sub-converters, so that the capacity and efficiency of the converter are improved.

    本发明属于电源变换技术领域,涉及一种三相双向交错变换器及控制方法。其中变换器,包括:滤波电感LA、LB和LC,分别和三相交流端UA、UB和UC连接;共模电感LMA、LMB和LMC的一端异名端和滤波电感LA、LB和LC连接;两个T型子变换器和共模电感的另一对异名端连接构成并联结构,两个T型子变换器的控制信号相位相差180°;其中T型子变换器的上、下桥臂和直流母线连接,中间桥臂和共模电感连接;电容C1、C2在直流母线上串联,中间桥臂连接于电容C1和C2的中点。本发明在两个子变换器引入移相控制,交错的两个子变换器可以减小输入或输出电流纹波,共模电感减小两个子变换器之间的环流,以提高变换器的容量和效率。
