| 摘 要： | 对ZCS DC／DC全桥变换器进行了全面的分析。由于所有的开关管均可实现ZCS，因此该变换器广泛应于大电压大功率场合。该变换器对于吸收器件的寄生参数，特别是吸收高压变压器的寄生参数．并对利用固定频率移相控制来实现ZCS有着非常明显的作用。详细分析了半周期的工作过程。并对之进行了稳态分析，提出了该变换器的一些主要特点。最后给出一台实验样机．对理论分析进行了有效的论证。

| Abstract: | This paper presents a comprehension study of a full bridge Zero-Current-Switched Pulse Width Modulation(ZCS-PWM) converter which is suitable for all high voltage and high power DC applications because all active switches can get ZCS operations.The given converter has great effects on absorbing parasitic parameters produced by the high power transformer,and employs fixed-frequency phase-shift control.The stages of the first half cycle and detailed steady state analysis of the converter are discussed.Some major features are given.At last,a prototype is also presented to validate the theoretical analysis effectively. |
