Abstract: Over the recent past, many methodologies to reduce DC bus voltage stress in the single stage single switch power quality converter have been proposed in the literature. The new development resulted in increased efficiency, reduced size and compactness. In this paper, a simple and inexpensive solution with a simple control for the reduction of DC bus voltage stress is proposed. This topology is the integration of discontinuous conduction mode (DCM) boost rectifier for the input current shaping and flyback converter for fast output voltage regulation. With a single active switch, this converter is capable of drawing high quality input current waveform, fast output voltage regulation with reduced bus voltage. No additional component is required to reduce DC bus voltage stress. A design solution and a simple controller is proposed to reduce DC bus voltage stress. As a result, this converter is best suited for universal line application (90-265 V AC). Performance of the converter, design guidelines, small signal analysis, and stability analysis are carried out.
