Z-Source Multilevel Inverter based AFLC PV System

This paper expansion a Multilevel Inverter assembled on Adaptive fuzzy logic controlled Photo voltaic scheme. The Symmetrical Phase Shift Modulation (PSM) technique is used and the active device present in the Multilevel Inverter produces a power loss with shoot-through problem. The proposed system consists of PV system, Z-source, Multilevel Inverter, AFLC controller. Z-source is second-hand to protect the Multilevel Inverter from the shoot-through problem and to diminish the switching loss before switching strain of the scheme. A switched-capacitor based cascaded multilevel inverter with Symmetrical Phase Shift Modulation technique is used. The controller is used to evaluate the performance of the proposed system and the output of controllers is compared. The model study of the proposed converter is supported by using MATLAB/Simulink with proposed nine level inverter.
