本文提出了一种新型的零电压开关（ZVS）脉宽调制（PWM） DC/DC变换器，用于高功率、高输出电压的应用。通过在变压器二次侧使用两个有源开关，该变换器不仅实现了有源开关在整个负载范围内的零电压转换，而且实现了输出整流二极管的软换相。该拓扑结构简单，控制策略简单。给出了一种2.8 kW 200khz DC/DC变换器的仿真结果和实验结果。
This paper presents a novel zero voltage switch (ZVS) pulse-width modulation (PWM) DC/DC converter for high power, high output voltage applications. By using two active switches in the secondary side of a transformer, the proposed converter achieves not only ZVS of the active switches in the entire load ranges but also soft commutation of the output rectifier diodes. The proposed topology has simple structure and control strategy. Simulation results and experimental results of a 2.8 kW 200 kHz DC/DC converter are presented.
