| Abstract: | 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 invariableness frequency occupancy is used,so that the appliance could become wide. |
