摘　　要：提出了一种新型零电压开关交错并联双管正激组合变换器。该变换器由两路双管正激变换器交错并联构成,共用一个高频变压器,提高了磁芯利用率。同时,该变换器保留了双管正激变换器开关电压应力低、可靠性高的优点。采用有限双极性控制,利用变换器副边谐振电感的能量来实现开关管的零电压开关。本文详细分析了该变换器的工作原理,并且给出了实验结果。This paper proposes a new Zero-Voltage-Switching （ZVS） interleaving dual-switch forward combined converter. This topology is composed of two interleaving dual-switch forward converters, and coupled through a single high frequency transformer, and the utilization of the core is increased. The converter remains low voltage stress of the switches and high reliability. Finite-bipolar control technique is introduced to realize ZVS for all switches with the use of secondary resonant inductor. The operation principle of the proposed converter is analyzed theoretically and verified by the experimental results.
