Reduced Switch Seven-Level Multilevel Inverter for Renewable Energy Applications

Abstract

The world is currently dealing with two major
issues. The first issue is a shortage of fossil fuels in the near
future, and the second is increased atmospheric pollution,
which leads to an increase in ambient temperature (global
warming), which necessitates the need to switch from
traditional energy sources to renewable energy sources (RES).
As the power generation from renewable energy sources is
increasing gradually, the importance of multilevel inverters is
also rising day by day for the grid integration of power
generated from renewable energy sources. In this paper, a
single-phase multilevel inverter is designed for the application
of renewable energy sources like Photovoltaic and Fuel cells,
etc. The chosen multilevel inverter configuration for the study
requires a lower switch count to generate multilevel output.
The sinusoidal pulse width modulation technique is employed
for generating control pulses for the multilevel inverter. The
performance of the model is analyzed by simulation in
MATLAB software.
