| Abstract: | The principle of charge pump for achieving power factor correction (PFC) and its unity power factor condi-tion are analyzed.A kind of two-transistor forward converter using charge pump PFC circuit is proposed in this paper.The operation principle of this converter is analyzed,the design method about the input inductor and the charge capacitor is discussed.A 100W prototype is built to verify the operation of this converter.The experimental results show that the con-verter can achieve high power factor,low THD and high efficiency. |
