Simulation of Single-Phase Cascaded H-Bridge Multilevel Inverter with Bidirectional Switches for Solar Photovoltaic Systems

Abstract

This article introduce a single-phase five-level inverter used for the SPV arrangement through a novel pulse width modulation (PWM) supervision system. Traditional inverters subsist of more power switches, low power quality, and rising switching losses. The proposed method composes the typical single-phase, single bridge by one bidirectional control. The inverter’s effectiveness generates input voltage by generating five production voltages (Vdc/2, Vdc, 0, -Vdc/2, -Vdc). Maximum Power Point Tracking (MPPT) was accomplished in SPV through a Fuzzy controller. The suggested technique is confirmable through simulation adopting MATLAB/SIMULINK and the PROTEUS model.
