Abstract :
A boost/buck-boost Power Factor Correction (PFC) converter with wide output voltage is proposed in this paper. The converter operates in boost mode when input is lower than output and in buck-boost mode when input voltage is higher than output voltage. In order to reduce the reverse recovery loss in both operating modes, the converter can achieve boundary conduction mode with a pseudo constant-on-time (COT) control. Furthermore, with the improved Pseudo-COT control the input line current keeps smooth during the operating mode transitions. Theoretical analysis and design considerations for the proposed converter and control strategy are presented and verified by a 150 W PFC prototype with universal input voltage and wide output voltage range from 200V to 400V.
