Enrichment in the Performance of Cascaded Multilevel Inverter Topology by Introducing Various Modulation Techniques

Abstract

In the development of green energy system solar energy shows a critical role in the place of power production but
the output of solar energy is almost DC, but the 75 percent feeding utilities are AC to fill this gap we are in the need
of a power electronic converter the most promising power converter to convert DC to AC is inverter, due this need,
in this paper we are going to implement the analysis on a cascaded multilevel inverter which can produce a 15
level output need for the industrial standard to enhance its performance based on its THD, Vrms & IRMS. By
applying various fundamental and high frequency modulation techniques on it, the highlights of the PWM techniques
are verified by applying the techniques on the existing seven level inverter once the performances are verified and
satisfied the same techniques has been implemented on the cascaded 15 level inverter and outputs are verified using
MATLAB/SIMULINK, compared with various inverter and obtained the best results basics of low THD & high Vrms
& IRMS values further the stability of the circuit are verified using hardware design.
