| Abstract: | A novel single stage power factor correction circuit with full bridge structure is proposed for applica- tion in middle or high power condition to perform power factor correction and AC/AC power conversion at the same time.Such problelms with a dual stages PFC circuit as complex circuit structure,too many components, low efficiency and high cost are solved.How to choose switch and its driving is discussed.The advantages of proposed circuit were verified by theoretical analysis and experiments. |
