Simulation of Single-Phase Cascaded H-Bridge Multilevel Inverter with Non-isolated Converter for Solar Photovoltaic System

This manuscript introduces an innovative single-phase cascaded H-Bridge multilevel inverter (MLI) through a minimum quantity of switches used on behalf of a Solar Photovoltaic (PV) application. Multilevel inverters are measured because of the power conversion system’s ability to support high power and power quality demanding applications. This manuscript intends to intend a modified cascaded Five-Level Inverter topology designed for a practically sinusoidal output voltage, fewer numbers of power switches, decreased complexity and reduced total harmonic distortion (THD). The composition is simple and easy to enlarge higher levels, but its gate driver circuits are also interpreted considering the number of operative switches is decreased. The pulse width modulation technique is employed through the multicarrier system to produce the gating signals supporting the power switches. This ability is attained by analyzing the proposed topology through the conventional topologies as the aforementioned observation point. The performance with efficient accuracy of the proposed topology by novel approach in generating voltage levels for a five-level inverter was proved over simulation using MATLAB/SIMULINK, PROTEUS results.
