Solar Powered BLDC Motor with HCC Fed Water Pumping System for Irrigation

Abstract

This project deals with the cost-effective BLDC motor drive powered from solar photovoltaic system with HCC fed water pumping system for irrigation. BLDC motor is preferred over other brush-based motors for its unique features like high efficiency, high torque and simple structure with low noise. As solar power is abundant and available at any place so the solar photovoltaic (SPV) array system is considered as the source. The modified incremental conductance maximum power point technique (MPPT) is used because of its advantage of providing soft starting to BLDC motor. To extract maximum available power from SPV array a buck-boost converter is used. By using conventional control strategies torque ripples are present, by introducing Hysteresis Current Control (HCC) torque ripple can be minimised. The main objective of this paper is to minimize the torque ripples occurring in BLDC motor drive using Hysteresis Current Control, which is simulated using MATLAB/SIMULINK platform.
