PROJECT TITLE :

BLDC Motor Driven Solar PV Array Fed Water Pumping System Employing Zeta Converter - 2016

ABSTRACT:

This paper proposes a straightforward, value-effective, and economical brushless dc (BLDC) motor drive for solar photovoltaic (SPV) array-fed water pumping system. A zeta converter is used to extract the most accessible power from the SPV array. The proposed control algorithm eliminates phase current sensors and adapts a elementary frequency switching of the voltage supply inverter (VSI), so avoiding the power losses thanks to high frequency switching. No extra control or circuitry is used for speed control of the BLDC motor. The speed is controlled through a variable dc link voltage of VSI. An acceptable control of zeta converter through the incremental conductance most power purpose tracking (INC-MPPT) algorithm offers soft starting of the BLDC motor. The proposed water pumping system is designed and modeled such that the performance is not affected beneath dynamic conditions. The suitability of proposed system at sensible operating conditions is demonstrated through simulation results using MATLAB/Simulink followed by an experimental validation.
