Abstract：The paper presents a front-end topology of a bidirectional switch power factor (Bridgeless-PFC), and digitized feedfoward compensation method is adopted to improve the quality of the input current under the traditional method of double control loop (PI). The system can reduce the impact of the switch between DCM and CCM, and attain a good result during the full power range. The theoretical analysis of the proposed method is deduced, and the experiment results are attained by using digitally controlled Bridgeless-PFC, which validate the proposed compensation method.
