Abstract A bridgeless boost rectifier with low conduction losses and reduced diode reverse-recovery problems is proposed for power-factor correction. The proposed boost rectifier can reduce the conduction losses and alleviate the diode reverse-recovery problems by using a coupled inductor and two additional diodes. A detailed analysis of the proposed boost rectifier is presented. Experimental results for a 300W prototype are also discussed to show the performance of the proposed boost rectifier. Dual Boost PFC (DBPFC) by nature brings higher EMI noise, the proposed boost rectifier can solve the problem very well. Saber simulation is performed to validate the EMI model and analysis, and it shows the same level with traditional Boost PFC.
