A new three-phase buck/boost/buckboost power factor correction rectifier is presented in this paper. For the converter, only two high-frequency switching actions exist in each sample period, and only one inductor is used. As a result, system efficiency can be improved. The commutation procedures are analyzed for the three modes, the controller design of the rectifier is discussed, and the output duty is assigned between switches according to different intervals of input voltage. Experiments are conducted to verify the effectiveness of the proposed rectifier.

新型高效多功能降压/升压/降压升压 PFC 转换器

本文介绍了一种新型三相降压/升压/降压升压功率因数校正整流器。对于转换器来说，每个采样周期只存在两个高频开关动作，并且只使用一个电感。结果，可以提高系统效率。分析了三种模式的换向过程，讨论了整流器的控制器设计，并根据输入电压的不同间隔在开关之间分配输出占空比。进行实验以验证所提出的整流器的有效性。
