Abstract：The peak current control is widely used in controlling power factor correction (PFC) converters. The fast time scale bifurcations appear in zero-crossing of input alternating current due to the time variation of input voltage. This instable phenomenon can seriously affect the performance of PFC converters. It is very important to take some measures to control the bifurcations in PFC. Theory of operation of PFC based on peak current control is analyzed in detail. The basic theory of causing the bifurcations in PFC converters is derived from theory analysis. The optimal method of selecting parameters of controller is proposed based on the resonant bifurcation control theory. The performance of PFC converters can be improved by eliminating the bifurcations of input current. The method of controlling bifurcations in PFC is verified by the numeric analysis simulations and experimental result.
