A Hybrid Topology for Multilevel Inverter Using Amplitude Modulation

Abstract

This paper proposed a new topology for multilevel inverter in this topology we are using bypass diode
technique and one H bridge to generate any levels. Due to this topology the cost of switches, driver circuit and
installation area are reduced considerably. Here this paper also proposed a two new formula one to decide number of
level generated according to source availability and other to determine time at which mosfet will be turned on and off.
The proposed topology works on Amplitude Modulation technique which increases efficiency but problem of Amplitude
Modulation technique is it needed different DC sources in multiple off 2. Here this paper proposed simulation of 127
level inverter. With its output waveform, FFT analysis, switching table and Fourier analysis.
