A POWER QUALITY IMPROVED BRIDGELESS KY CONVERTER BASED COMPUTER POWER SUPPLY
Keywords:Bridgeless converter, PFC, input current, computer power supply, KY converter.
This project introduces a design, analysis, simulation and improvement of power factor (PF) multiple output Switched Mode Power Supply (SMPS) using a bridgeless KY converter is used as the first stage. The first stage buck-boost converter is designed in Discontinuous Conduction Mode (DCM) for inherent power factor correction (PFC). Comparing with conventional topologies the proposed topology reduces conduction losses and improves power quality. Both simulation and experimental results demonstrate the improved performance of the proposed SMPS.
