Multilevel Inverter Fed 1- Φ Asynchronous Motor Based Water Pumping System

Multilevel inverters (MLI) assisted water pumping system is gaining more popularity in various applications as it can be easily extended to the photovoltaic system which can used in the absence of main supply. In this paper the fifteen level MLI is used to test the performance of Induction Motor water pumping system using various PWM techniques. The switching sequence for the MLI is obtained using level shift pulse width modulation technique to reduce the total harmonic distortion. The entire system is executed using MATLAB and validated with experimental setup.
