Novel 13-level Asymmetrical Photovoltaic Inverter with Reduced switches

Abstract

The demand of Photovoltaic (PV) connected multilevel Inverter for higher power applications in industries and home has been increasing rapidly. This paper proposed a new asymmetrical multilevel inverter (AMLI) topology, which can reduce the switches for PV application. The proposed 13-level Inverter, only eight power electronics switches are uses to generate 13-level of output voltages. The simulation, as well as experimental results of the inverter voltage and current at RL load, are presented. The proposed Inverter validity is tested with MATLAB/SIMULINK and real-time simulator Dspace (DS1103) and implement laboratory prototype hardware.
