摘　　要：引入一种双向开关前置的单相升压APFC变换器拓扑,把双向开关放置在整流桥前端,较好地解决了传统单相升压APFC变换器电路置后的升压电感直流偏磁问题。本文介绍该电路的结构,分析研究电路的各种工作状态,对该拓扑进行了小信号建模,最后利用Matlab软件对该变换器电路进行了仿真分析。A prepositional bidirectional Switch, single-phase, boost, aetive-power-factor-correction converter topology is introduced in this paper. The bidirectional switch is placed before the rectifier. This paper analyses and investigates the topology＇s structure and various work station, establishes the small signal modeling of the topology and also simulates the converter with Matlab software.
