【摘要】 文中提出了一种无中间直流环节的AC/DC开关电源电路,并阐述其工作原理,分析了由于取消整流和一次侧直流滤波电路而导致输出电压出现的问题,以及为解决该问题而采取的控制策略,并给出仿真与实验结果。更多还原

【Abstract】 This Paper introduces a kind of AC/DC switching power supply-circuit without medium DC link, describes the principle in detaiL. The control strategy is presented based on the problem deriving from the repeal of rectifier and the DC filter circuit. The results of simulation and experiment are given at the same time .更多还原
