In this proposed new converter is an inherent integration of a buck converter and a flyback converter, which operates in either fly back mode or buck mode according to whether the input voltage is lower or higher than the output voltage. In this way, the dead zones of AC input current in traditional buck PFC converter are eliminated. Therefore, the proposed integrated buck - fly back non-isolated PFC converter can achieve high PF under universal ac input range. A proposed converter will be simulated in Matlab/Simulink environment.
