This paper introduced a Buck PFC converter topology and its controlled method which is adopt the deadbeat algorithm for predicting the average current control,it reduced the system delay and improve the current loop performance of the system.The system simulation of Buck PFC converter with predictive averaged current mode control with Matlab is established.The simulation results prove that the Buck PFC converter with predictive averaged current mode control has low harmonic current,high input power factor and the new current predictive algorithm can improve the dynamic response of the system.
