Abstract :
Typical boost power factor correction (PFC) circuits have significant switching losses which reduce their efficiency. Resonant PFC circuits have been proposed to overcome this drawback but these circuits operate with higher RMS currents and thus higher conduction losses. A single phase, quasi-resonant rectifier that operates with unity power factor and with reduced conduction losses is proposed. In the paper, the modes of operation of the converter are explained and analyzed, the method of input current control is discussed, and a design procedure is derived. The feasibility of the converter is shown with results obtained from computer simulation
