single-stage full-bridge PFC converter circuit
PFC technology has been gradually integrated into a lot of good converter circuits. The new developed structures can well suppress power supply to input harmonics, regulating the input current’s waveform. They also have excellent output characteristics, fully achieving the advantages of PFC circuit and power conversion circuit. The figure shows the single-stage PFC circuit formed by the Boost circuit and full-bridge converter. As for practical applications, the synthesis circuit improves the charging and discharging circuit of VDx1 and VDx2, thus leading to better functions.
