摘要

一种新型的交流-直流开关变换器使用磁放大器(磁放大器)作为可控开关，在单个功率级上提供统一的功率因数。磁放大器控制整流线路电流，而快速输出调节是通过主动开关的脉宽调制(PWM)独立提供的。这些拓扑结构的总体功能是在单个变换器中提供重量轻、处理效率高、具有统一功率因数和快速输出调节的交流电源。实验结果验证了用磁放大器b>进行输入电流整形的新方法

Novel single stage AC-to-DC converters with magnetic amplifiers and high power factor

A novel class of AC-to-DC switching converters use a magnetic amplifier (magamp) as a controllable switch to provide unity power factor on the line in a single power stage. The magamp controls the rectified line current, while the fast output regulation is provided independently through pulse-width modulation (PWM) of the active switch. The overall function of these topologies is to provide light weight and efficient processing of the AC electric power with unity power factor and fast output regulation in a single converter. Experimental results are presented to verify a novel method of input current shaping with a magamp.<>
