PV Fed Bridgeless DC Motor using Zeta Converter for Water Pumping

Abstract

Solar energy is a renewable resource which is free of running cost and abundant in nature. The solar energy that is extracted using zeta converter can be used for store the battery and to drive Brushless DC motors for water pumping applications. Bridgeless DC motors fed from Photovoltaic cell through VSI (voltage source inverter) which has power from a dc link capacitor at the front end. Solar energy converted into voltage. Zeta converter regulates the DC link voltage for voltage source inverter. The proposed system has a Ceramic capacitor is used in replace of dc link capacitance with RL and RC branch. The proposed system can be elimination of electrolytic capacitance it can be reduce the ripple around 5% of original value.
