Review of PV fed water pumping systems using BLDC Motor

Abstract

Energy demand is increasing significantly nowadays due to increase in population, industrialization and transportation. The fossil fuel depletion is high with this increase in energy demand. There are sincere efforts from around the world to tap renewable sources and adopt these sources of energy for their social and economic development. Among all the available renewable energy sources solar energy is regarded as the most viable source of energy. Solar water pumping systems are receiving wide attention in agricultural and industrial sector as they are environment friendly and require no fuel cost. Conventional water pumps run by electricity tend to be unreliable and diesel pumps have increased fuel cost. Main objective of this study is to present a comprehensive literature review of Solar Photovoltaic fed water pumping system using Brushless DC(BLDC)Motor. BLDC motor emerges as a better substitute for DC motors and AC Induction Motors in water pumping applications due to high efficiency, high reliability and least maintenance requirement. The review focuses on research findings of solar photovoltaic water pumping systems using BLDC motor drives with and without dc-dc converters.
