Abstract

In this paper, a novel control method is proposed based on energy balance principle in the circuit for hybrid conduction mode (HCM) boost power factor correction (PFC) rectifier. The proposed control method is universal for both the continuous conduction mode (CCM) and the discontinuous conduction mode (DCM). With this superiority, no mode transition is needed inside one mains half-cycle when operating in HCM, and thus high-quality input current can be achieved. And the proposed control method is simple to implement but rather effective. Simulation results show significant improvement compared with conventional control methods.
