Experimental Validation for A Nine-Switched 3-phase Multilevel Inverter (MLI) with a Photovoltaic (PV) Source of Array

Abstract

Now-a-days Usage of Multilevel Inverters application is very wide in the industrial applications. Keeping in view of industrial applications, a multi-level inverter with a solar PV array is designed in this paper to deliver power to the Alternating Current based load. A step-up converter is used at the input side of the three-phase multilevel inverter, which delivers the energy for the three-phase load, to regulate the output voltage of the solar Photovoltaic panel. The multilevel inverter utilizes 9 switching devices with five level sources in accordance to the usage of the level of sources in recent topologies. However, the advantage of this topology is that it uses fewer semiconductor switches than current topologies. Eventually, the paper includes the results of the modelling in the MATLAB and the experimental implementation of the proposed topology.
