21 Level inverter topologies

This paper presents the effective and important topologies be found of diode clamped inverter (neutral point clamped), capacitor clamped inverter (flying capacitor) and cascaded multicell inverter. An outline of the multilevel converters with a concentrate on succeeding minimum harmonic distortion and high efficiency at low switching frequency operation. Multilevel converters are taken into consideration nowadays as the modern power conversion systems for high power and high-power quality requiring applications. This multilevel inverter produces 21 levels and results are approved through the harmonic spectrum of FET window by utilizing MATLAB Simulink.
