The present work deals with five level reduced device count multilevel inverter topology for a single-phase standalone solar photovoltaic based power generation system. The essential switching design presented here is used to reduce the selective lower order harmonics from the output voltage. The DC-DC voltage regulator is used to obtain stable DC output from standalone solar photovoltaic system for which the Perturb and Observe algorithm has been used to obtain maximum power operating point technique (MPPT). The complete control technique has been explained with the help of different modes of operation for five level output voltage with only six Insulated Gate Bipolar Transistor and two diodes to extract maximum amount of solar photovoltaic energy to increase fundamental output voltage with minimum harmonic contents. The performance of presented system has been simulated and tested in MATLAB simulation environment. The analysis of harmonic content in the output voltage and current has been carried out for the system under test.
