Design and Simulation of single-phase 3 kW PV inverter

Abstract

This research provides a complete analysis of photovoltaic (PV) inverter of 3kW output power by merging the design of PV array and DC-AC inverter; The design includes a PV module to configure a large array that agrees with the inverter power output, the DC-DC step-up (boost) converter, next the full-bridge using MOSFET switches controlled by PWM (Pulse Width modulation) is used to generate three levels signal and the output LCL filter design, then to the load. Also studying the inverter parameters that affect the losses and inverter efficiency. The design is verified using Matlab-Simulink simulation using parameters of a real PV module, switches and passive elements to be close to practical work. The simulation results prove the design output consistency.
