Abstract
For large-scale water pumping applications including farm irrigation and water for drinking delivery, electrical pumps are frequently employed. But locations that are not linked to the public electrical distribution network cannot use electric pumps. Such remote locations require the use of electric pumps powered by RES like solar energy systems. Consequently, in recent years, interest in solar-powered water pumping devices has surged. It is suggested to use an upgraded Landsman converter supplied BLDC motor in a solar-powered water pumping system. It offers a water pumping system powered by PV that is functional and economical. The BLDC is switched using an upgraded Landsman converter with lower cost and volume. The water pump is further driven by a BLDC motor, which is connected to a 3∅VSI, which transforms the DC voltage to its corresponding AC voltage. In order to increase the PV output power and maintain it at its maximum under variable irradiance, a modified P&O MPPT controller is employed. Between a solar energy system and a motor-pump drive, an improved Landsman converter functions as a DC to DC converter where it achieve a voltage gain of 1:12 and efficiency of 97.42%. MATLAB Simulink model is used for simulating the entire system.
