摘要：
This paper introduces the design and analysis of Zero Voltage Switching (ZVS) scheme of solar powered Z-Source Inverter (ZSI) topology for the UPS applications. The ZSI topology employs a unique impedance network which couples the solar power and the utility. A resonant circuit is designed to obtain ZVS of ZSI, thereby voltage stress across the inverter switches are minimized. The proposed configuration reduces the switching loss and improves the utilization of solar power. Moreover, it highly enhances the reliability of the inverter because the shoot through no longer destroys the inverter. The entire system is developed and simulated using SIMULINK tools. The performance of the proposed system is analyzed and necessary simulation results are obtained. A prototype model of single phase soft switched ZSI is developed and its results are validated.
