Photovoltaic (PV) array assisted water pumping systems are gaining more popularity in household and agriculture applications in absence of grid power. In this paper, the investigations on performance of a PV based multilevel voltage source inverter (VSI) powered Induction motor (IM) based water pumping system. The neutral point diode clamped (NPC) inverter with sinusoidal pulsewidth modulation (SPWM)...
