Solar Powered Water Pump with Zeta Converter and BLDC Motor

Abstract

In nature, solar energy is a plentiful and essential renewable energy source and doesn't require continuous operating costs, even though the initial installation cost may be higher. Solar energy is captured and utilized to power motors for a variety of uses. Direct current (DC), induction, and brushless DC (BLDC) motors are the types of motors used in these applications; the latter kind offers more widely used benefits. Using a ZETA converter in a PV system is the focus of this project. To obtain maximum PV system efficiency and enable a soft start for the PV system, a water pump can act as an inverter (VSI), acting as a mediator in the DC-DC conversion process between the photovoltaic system and an energy source. A brushless DC (BLDC) motor with permanent magnet is driven by an appropriate control system. With two inductors and two capacitors, the Zeta converter functions as a DC-DC converter with a fourth-order configuration that can function in both buck and boost modes. A brushless DC motor drives a centrifugal water pump because it is compatible with the PV generator's maximum output position. The water pumping system that is recommended driven by a Zeta converter and operated by a BLDC motor, is assessed under rapid and slow changing atmospheric circumstances utilizing the power systems simulation toolboxes of the MATLAB/Simulink environment. The suggested solar water pumping system is the subject of modeling, simulation, and experimental validation in this paper. To examine the system's performance under various load and solar irradiation scenarios, simulations are run. To confirm the viability and efficacy of the suggested method, a working prototype is also created and put to real-world testing. The results show that adding the Zeta converter in solar water pumping technique to the BLDC motor significantly improved the dependability and efficiency. The system exhibits efficient power management, guaranteeing the best possible use of solar energy for the purpose of pumping water. In areas where traditional power sources are unavailable, our research advances environmentally friendly and sustainable water pumping systems. The project's conclusions offer insightful information for creating durable, extremely effective, and energy-efficient solar-powered water pumping systems.
