Abstract :
DC/DC power converters have been widely used in industrial applications. Since the classical converters and switched inductor converters have high power losses across the switches during switching-on and switching-off, the power transfer efficiency of these converters is limited. Soft switching technique implements the zero-power-consumption operation during switching-on and switching-off. Therefore, it largely reduces the power losses of the converter. Most of the papers in literature introduce the zero-current-switching (ZCS) and zero-voltage-switching (ZVS) methods in single quadrant operation. This paper introduces a two-quadrant DC/DC zero-voltage-switching (ZVS) quasi-resonant-converter Luo-Converter, which effectively reduces the power losses, and largely increases the power density and power transfer efficiency. Experimental results verified the advantages of this converter
