Design And Development of BLDC Motor Drive For Solar-PV Irrigation System Using MATLAB

In recent time energy based on renewable sources is the best long term alternative solution compare to the conventional fossil fuel energy resources, solar photovoltaic array (SPV) based irrigation water pump has gained more popularity. In this paper study has been done with proper utilization of available solar energy which is fed to BLDC motor for irrigation purpose in agricultural field. Between PV array and three phase inverter (VSI) and in between DC-DC boost converter is used for smooth starting operation of BLDC motor by proper control mechanism. To enhance efficiency of solar PV array the IN-C MPPT algorithm method is used. With Pulse width modulation (PWM) method along with DC link bus voltage regulator the speed controlling operation of BLDC motor is performed. High efficiency, reduce dependency on grid and petroleum fuel-based pumping system, are the main key features considered in this paper. The dynamic and steady state performance of given system are simulated under different atmospheric condition using various blocks of MATLAB-Simulink software environment.
