Solar Photo Voltaic Based Water Pumping Using BLDC Motor

Abstract

The Solar energy is main source of power. In our day-to-day life the polluting devices replace many solar powered devices. This paper determines the usage of solar power to run the BLDC motor by using a buck converter. The BLDC motor is used to get the maximum efficiency. the converter is also used for the maximum efficiency and also for getting the desired output. Also, the converter component is the only one that allows for continuous monitoring of the PV array's maximum power point. The maximum power point tracking is done by using the LDR (light dependent resistor). The shaft of the BLDC motor is mutually coupled with centrifugal pump to pump the water. In Simulation using MATLAB, the performance characteristics of a solar PV driven BLDC motor drive using a buck converter are analyzed in various conditions, including steady state and transient characteristics.
