FIVE LEVEL INVERTER FOR RENEWABLE POWERGENERATIONSYSTEM

Abstract

The usage of single-stage, single-phase inverters is on the rise among smaller photovoltaic (PV) systems due to regulations about green energy and shifts in the electricity market. Many people find that using transformers with three stages or more significantly increases their efficiency. The research concluded that photovoltaic (PV) systems should use inverters with one stage and five levels. The inverter's output current varies in response to changes in the photovoltaic (PV) grid voltage. The Sinusoidal Pulse Width Modulation (SPWM) architecture is the basis of this control method. Since SPWM simplifies the connection between the generator and the grid and eliminates the requirement for a phase-locked loop, it is finding increasing usage in a variety of technologies. The five-level inverter is demonstrated to function properly using Matlab models.
