| Abstract: | In this paper,a new two-switch topology,Buck+Boost,was proposed.A detailed analysis of converter operation and component stresses was given,presenting a new control strategy for average current control,which is an extension of conventional average current control method.There are two independently control switches in wide input power factor correction(PFC) circuits.The simulation results proved the feasibility of control strategy,and demonstrated that Buck+Boost can be well applied to the wide input power f... |
