Abstract: Single-phase active power factor correction (PFC) circuit is a double closed loop control system. Based on the analysis of PFC working mechanism, the dynamic model of the system is built. The closed-loop structure figure as well as transfer function of each part are present. Also, the function and the designing method of current loop and voltage loop are explained in this paper.
