Solar PV Array Fed Zeta Converter Controlled BLDC Motor Based Water Pumping System
Abstract
This paper proposes a simple, cost effective and efficient brushless DC
(BLDC) motor drive for solar photovoltaic (SPV) array fed water pumping system.
A zeta converter is utilized in order to extract the maximum available power
from the SPV array. The proposed control algorithm eliminates phase current
sensors and adapts a fundamental frequency switching of the voltage source
inverter (VSI), thus avoiding the power losses due to high frequency switching.
No additional 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
appropriate control of zeta converter through the proportionate integral
maximum power point tracking (PI-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 under dynamic conditions. The suitability of
proposed system at practical operating conditions is demonstrated through
simulation results using power sim followed by an experimental validation.
