摘要
谐振变流是现代电力电子技术近年来发展最快的前沿领域之一．本文介绍了一种全桥零电压开关脉冲频率调制式准谐振变流器（ＦＢ—ＺＶＳ—ＰＦＭ—ＱＲＣ），以及它的工作原理和实现“软开关”的关键无件参数的计算方法，具有一定的实用和参考价值．
The resonant conversion technique is one of the ranges which have been rapidly developing these ten years in power electronics. A Full-Bridge Zero-VoltageSwitching Pulse-Frequency-Modifying mode quasi resonant converter (FB-ZVS-PFM QRC),its operating principle and calculation of the important paramenters for'soft switching'are introduced in the present paper,which will be useful for reference in practice.
