摘要
Totem pole bridgeless PFC operates in Mixed Conduction Mode (MCM) based on one cycle control (OCC) is proposed with digital controller, which will reduce boost inductor size, keep low input current total harmonic distortion (THD) in wide load range. The transition principles between CCM and DCM is analyzed in detail, and a virtual resistor is introduced for control stability. Simulation results verify the control strategy and input current THD is 1.73% at rated condition.
