摘　　要：通过分析开关电源应用中出现的一些新问题,考虑国际上对通用电器输入电流谐波的限制,提出一种新型的,结合低成本、高性能充电泵功率因数校正电路的开关电源方案.实验结果表明,该方案采用的单极拓扑结构,降低了成本,恒频占空比控制方式使控制电路变得简单,应用性大大提高.Based on the analysis of some problems existed in the practical application of switching power, and the limit of the input harmonics of home appliance in international, a novel switching power with charge pump power factor correction characteristic of a low cost and good performance is presented. The experiment result shows that in the scheme the cost can be reduced if the single topological structure is adopted, and the control circuit becomes simple if the control model of the control model of invariableness frequency occupancy is used, so that the appliance could become wide.
