Analysis of Five Level Cascaded Multilevel Inverter Using Variable Frequency Multi Carrier Pulse Width Modulation Techniques

Shani M Vaidya, Kunal P Bhatt

Abstract: Multilevel inverters are uses in the many high power application, it has many advantages due to the controllability of the series connected switches. In this paper presents the different variable frequency multi carrier modulation pulse width modulation techniques modeled in MATLAB Simulink. The analysis cascaded multilevel inverter using the different modulation technique schemes is done and finally the results are compared. The main objective of this work is to select the best control and switching topology for the multilevel inverter.
