Solar PV fed Proposed Simple Boost Controlled Z-Source Inverter for Grid

Abstract

This paper presents a proposed model of Impedance-Sourced Inverter (ZSI) for the Three-Phase PV System which is further connected to the grid. ZSI implements shoot-through mode for controlling output voltage which differs from conventional VSI. Shoot through mode is implementing in ZSI for performing the buck-boost operation on Input Voltage by modification of the conventional PWM Technique. Power Conversion of Single Stage is achieved by the Z-source circuitry. Validation of output results is achieved by simulating the PV module in the MATLAB/Simulink platform.
