Usage of the consumer electronics products such as TVs has increased rapidly with the emerging technological developments recently, hence limiting the power consumption of such devices have become more and more crucial. Switched Mode Power Supply (SMPS) topologies that allow higher efficiency than linear supplier became prevalent after the 1960s. Flyback converter is one of the SMPS topologies and very popular in low power applications because of multiple outputs, design simplicity and low cost. In this work, quasi resonant switching based flyback converter is analyzed, design equations extracted and designed with given parameters. Also power loss model of converter is analyzed and verified with practically results.
