摘要
介绍一种新的单相开关整流器的控制方案,它采用有源电流波形整形技术来控制输入电流连续导通,其控制开关的周期是固定的,导通时间的大小是根据输入电流的斜率进行调控。论述该控制方案具有不需要电流传感器、线路功率因数高、电路简单等特点。理论分析和实验结果证明了该控制方案是可行的。
A novel control scheme for single-phase switch-mode re ctifiers is presented in this paper. It adopts an active current wave-shapi ng technique to control continuous conduction of input current. Its switching-cy cle is constant, conductive time is based on the available input curre nt slopes to modulate. It features eliminating current sensing, unity pow er factor and simple circuit. Theoretical and experimental results confi rm the validity of the presented scheme.
