Abstract
This paper addresses an approach to improve the efficiency of the quasi-Z-source (qZS) converters. By replacing the qZS diode by the n-channel MOSFET, the power loss over a diode can be reduced in a qZS network. The paper presents operation basics of the approach, analysis and comparison of the power losses of the traditional and proposed designs and experimental validation of the theoretical assumptions.
