Modelling and implementation of single-phase Z-source inverter using arduino

Abstract

This paper presents a single-phase Z-Source Inverter simulation and hardware implementation using Arduino. Z-Source converter uses single stage conversion topology to provide both voltage boost and buck operations. It activates boost property by using shoot-through state that cannot be found in conventional voltage source and current source inverters. The switches of the same phase leg can be switched on using shoot-through state. This improved Z-source technology utilizes less number of switches and increases efficiency of the inverter with less cost. Simulation is done in MATLAB Simulink. Both simulation and hardware results are compared.
