新型高功率因数UPS的研究

摘要

The power factor correction is always a very important part of power and electron technology. In order to improve the voltage gain and improve the efficiency of the Boost converter, a zero-voltage-transition (ZVT) Boost converter with low switching voltage stress is proposed. The operating principle, working process and performance characteristics of this new con-verter are analyzed in detail. The experimental results proved the correctness of the theory analysis.%在电力电子技术中,功率因数校正技术一直是其非常重要的组成部分.针对如何更好的提高Boost变换器的电压增益以及提高其变换效率问题,采用了一种低开关电压应力ZVT Boost变换器,对其工作原理,工作过程和性能特点进行了详细分析,并进行实验研究,实验结果证明了理论分析的正确性.
