چکیده
This paper presents the most important multilevel inverter topologies like diode-clamped inverter (neutral-point clamped), capacitor-clamped (flying capacitor), and cascaded multicell( H-Bridge ) with separate dc sources. A Comparison of 5-level hybrid cascaded inverter with PWM method, 5 level diode clamped inverter & 5 level capacitor coupled inverter is also presented in this paper. This paper also presents the most relevant control and modulation methods developed for this family of inverters i.e. multilevel sinusoidal pulse width modulation. A simulation model based MATLAB/SIMULINK is developed for hybrid cascaded multilevel inverter, diode clamped multilevel inverter & Capacitor clamped multilevel inverter with PWM control method. The results experimentally validate the proposed paper.
