| Abstract: | This paper presents a UC3854-based control strategy for zero voltage transition active power factor correction(ZVT-APFC).The operating principle of ZVT circuit is described and the driving circuit of the auxiliary switch composed of discrete components is emphatically analyzed.The results of experiments verify the stabilization and reliability of the proposed driving circuit.Then the good performance of this ZVT-APFC circuit is sufficiently testified through efficiency comparison.In contrast to UC3855-based circuit,this control circuit possesses several advantages,such as simpler,more reliable,lower cost and so on. |
