Abstract

This study presents the analysis, design and voltage regulation of a zero-voltage switching quasi-resonant-positive output super lift Luo converter with low switching losses for industrial applications requiring regulated output voltage. To increase the power packing density, a simple control method using an analogue resonant controller UC3861 is used to regulate the output voltage against load variation and supply disturbance. The performance of the controller is verified by developing a prototype model of the converter and experimental results are presented. The results reveal the superiority of using a single dedicated IC for voltage regulation. Also it is observed that the converter provides maximum efficiency of 95% at full load.
