Solar powered multilevel dc fed simplified inverter

Multilevel converters and inverters are the emerging power conversion technology for distributed energy systems and industrial motor drives. Single phase inverter is widely used for stand-alone systems and micro-grid application. The major problem faced by multilevel inverters are, number of switches required large which leads to higher switching losses. A novel solar powered multilevel dc fed simplified inverter is proposed, in which a single phase multilevel output can be attained using less number of switches. This paper observers the feasibility of the proposed topology using Matlab/Simulink software. A nine level output voltage is obtained with less harmonic content and reduced switching losses.
