摘要
提出了一种隔离直流-直流变流器,此变流器由两个零电压开关脉宽调制式(PWM)正向变流器串联并与一个高频变压器耦合而成。此变流器的特点是从空载到满载运行时无开关损耗,且导通损耗也较低,它适用于高输入电压和大功率的应用场合。阐述了变流器的工作原理、理论分析和设计举例,并用一个实验原型验证了理论推断。
A twin zero voltage switching PWM forward converter is presented. It is connected in series and coupled by a high-frequency transformer. The converter features no switching losses from zero-load to full-load operation and low conduction losses. It is suitable for high input voltage and high power applications. This paper presents its operation principles, theoretical analysis and a design example. The experimental results of a laboratory prototype confirm the theoretical inference and analysis.
