Closed Loop Analysis of Single-Phase Soft-Switching PFC Converter

2 Abstract: Generally converter when operated at high frequency results in losses. In this paper a single stage soft switching PFC converter analysis is done. It is developed with a new active snubber cell which provides zero-voltage transition turn ON and zero-current transition turn OFF. This type of converter circuit design does not have additional resonant components. Operating the proposed converter at high frequency, the soft switching scheme will reduce the electromagnetic interference. The simplified closed loop analysis is done to improve the overall efficiency by having good regulation capability. The simulation part is done with Matlab Simulink
