Photovoltaic Powered Induction Motor Drive Using a High Efficient Soft Switched Sazz Converter

Induction motor drive is the backbone of industrial societies. It also finds its application in Electrical vehicles. It is extensively required in rural areas for agricultural purposes, pumping drinking water, and in a water treatment process. Moreover, the necessity of switching from conventional means of generating energy to renewable methods has become the order of the day owing to its prime advantages of non-polluting nature and economic reasons. Hence, this paper addresses the implementation of a high efficient soft switched Snubber Assisted Zero Voltage and Zero Current (SAZZ) converter topology, integrated with a photovoltaic source, to power a three-phase Induction motor through three-phase inverter. Sinusoidal Pulse Width Modulation (SPWM) scheme is used for controlling the operation of the inverter employed. Variable frequency controller is utilized to control the speed of the Induction motor at a user defined value, in the midst of changing load conditions. Realization of the proposed work is carried out in Matlab atmosphere. The simulated results of the suggested work are compared with the Boost converter to validate the enriched response of the SAZZ converter.
