AC-DC Flyback Converter for Outdoor LED Lighting

An AC-DC flyback converter for outdoor LED lighting is proposed. In the proposed converter is designed to be operated in the discontinuous-conduction mode (DCM) to achieve a high power factor. A DC-DC flyback module is designed to provide input-output electrical isolation. This improves safety. In addition to this, a low-voltage-rating capacitor can be used as the DC-bus. PSIM based simulations are carried out. This paper addresses a novel approach for designing and modeling of the isolated flyback converter. A detailed analysis and simulation are conferred for flyback converter in discontinuous conduction mode (DCM).
