Summary:In this paper, Inductor Average Current Mode Control (IACMC) is proposed to regulate single phase Power Factor Correction (PFC) Buck-Boost Converter (BBC) operated in Continuous Conduction Mode (CCM). The Proportional-Integral (PI) controller is acts as an outer voltage loop and the IACMC is used in the inner current loop for PFC BBC. The proposed IACMC has advantages such as robustness when there are large variations in line voltage and output load. The PI controller is developed by using state space average model of BBC. The simulation of the proposed system with its control circuit is implemented in MatLab/Simulink. The simulation results show a nearly unity power factor can be attained and there is almost no change in power factor when the line frequency is at various ranges.
