Design Switched-Inductor Z Source Cascaded Seven Level Inverter for Solar Photovoltaic System

Multilevel inverter presents attractive advantages over conventional when applied in photovoltaic (PV) power systems. in this article discusses Z-source cascaded multi-level inverters applied to the photovoltaic system. we connect Each PV panel by two different topologies of Z-source inverter, traditional ZSI then we suggested switched-inductor Z-source inverter to achieve high boost capability with a very short shoot-through zero states to obtain high gain voltage conversion. This work proposes an improvement of the Z source network multilevel inverter. The simulation of single phase, seven-level Z-source cascaded is executed using MATLAB/SIMULINK.
