Irrigation Pumping Scheme Based on Solar PV and Zeta Converters with PMBLDC Motor

This paper proposes the concept of developing and implementing an energy-efficient, inexpensive, efficient, and pollution-free water pumping scheme for irrigation application, leveraging the advantages of a Zeta converter and PMBLDC motor, which would assist farmers in reducing their contemporary farming hurdles, thus improving productivity and quality of life. It presents an excellent device that consists of a PMBLDC motor fed from a renewable source, specifically a PV array with a Zeta converter used to achieve the total power output from the installed PV array through MPPT. This unique arrangement does away with phase current sensors and replaces them with VSI fundamental frequency switching, which in turn helps to prevent power failure due to high-frequency switching. The PMBLDC motor does not need any circuitry to operate. It is regulated by the VSI's variable DC connection voltage. It also introduces a novel concept for entirely eliminating the DC-connected capacitor, which resulted in unnecessary bulky and increase in the motor's cost. However, this removal causes torque ripple at the motor's output. A ceramic capacitor and switch have been used instead of a conventional DC component capacitor to reduce torque ripple subsequently. The findings of the MATLAB simulation model have been demonstrated periodically with the required illustration.
