Hardware Implementation of Z-Source Inverter for Commercial Applications

Abstract

This study gives an overview of z-source inverter and the methods to control it. The z-source inverter (ZSI) shown here is for dc-dc conversion, thus acting like a voltage source inverter. Here the technique of z-source inverter can be used for even ac-ac, ac-dc conversions. Since its invention the impedance-source inverter has presented us with many pros when compared to classical voltage or current-source converters. The simulation of a single-phase $\mathrm{Z}$ Source inverter controlled by pulse width modulation is illustrated using MATLAB to demonstrate the inverter's fundamental operation, and hardware findings are also reported in this work.
