BLDC Motor Driven Solar PV Array Fed Water Pumping System Employing Zeta Converter

Abstract

This paper deals with the usage of ZETA converter and a three-phase voltage source inverter for utilizing the power from a solar photovoltaic array to drive a Brushless DC motor. Here ZETA converter is used to maximize the power output from the solar photovoltaic system. The three-phase voltage source inverter (VSI) is implemented to obtain a maximum efficiency and to achieve a soft starting of BLDC motor for a smooth operation. The proposed algorithm for voltage source inverter (VSI) control utilizes fundamental frequency switching and the need for phase current sensors has been eliminated which results in reduced power losses at high switching frequencies. A variable DC link voltage of VSI controls the speed of BLDC motor and thus eliminating any usage of separate speed control units.  The proposed system is implemented for water pumping system and designed to operate under any dynamic conditions without any change in performance which is demonstrated by the simulation in powersim software and through practical hardware verification.
