Abstract

This paper involves design and simulation of a step up dc/dc converter topology connected with the chopper circuit intended for resistive and inductive load. The topology contains voltage fed qzsiZ Source Inverter (qzsi), a high frequency isolation transformer withreduced turn’sratio, a Voltage DoublerRectifier (VDR). A carrierbased Pulse-Width Modulation (PWM) which employs shootthroughstate strategy for qzsiis implemented which givessignificantly high voltage gain compared to traditional PWMtechniques. To improve the power density of converter, threephaseac-link and three-phase VDR is implemented. The designed step up dc/dc converter is tested for various kinds of resistive and inductive load inMATLAB/SIMULIKN platform
