A 31 LEVEL Asymmetrical Cascaded H-Bridge Multilevel inverter (ASCHBMLI) with DC-DC Fly back converter with single DC source for photovoltaic system using Maximum Power Point Tracking system. In this paper the photovoltaic (PV) system is given input to the primary side of DC-DC converter, where as the secondary side of the converter consists of 'n' no of turns with different output voltage. In Maximum Power Point Tracking (MPPT) system, the Perturb and Observe (P&O) technique is used for controlling the switch in DC-DC FBC. The topology is based on a cascaded connection of single phase sub multilevel converter unit and full bridge Cascaded H Bridge Inverter. The Input DC voltage source of Vdc1,Vdc2,Vdc3 & Vdc4 are designed in binary form of voltage of 15Vdc1,30Vdc2,60Vdc3 &120Vdc4 respectively. The output voltage levels are 2∗(1+2+4+8) +1=31) 31 level .The low frequency Pulse Width Modulation Technique is used for controlling the Power semiconductor Switches in the ASCHBMLI. © 2017 IEEE.
