Abstract

This project presents a single-switch single power-conversion (S3PC) power factor correction (PFC) converter. The control algorithm derived from feedback linearization enables the S3PC converter to obtain good controllability. The proposed converter performs both PFC control and output power control through single power-conversion. The S3PC converter provides high efficiency and high power factor in excess of 0.994.. The proposed converter is able to offer low cost and high power density in step up application due to the following features: ZCS turn-on and ZVS turn-off of switch and ZCS turn-off of diodes regardless of voltage and load variation; low rated lossless snubber; reduced transformer volume compared to fly back based converters due to low magnetizing current. The proposed converter is able to offer high power density in step-up application because of its simple structure; low rated lossless snubber; reduced transformer volume compared to isolation based converters due to low magnetizing current. The proposed converter is capable to stabilize the output efficiency. Experimental results are provided to validate the proposed concept. The Simulation is done with the help of MATLAB Software using Simulink.
