ABSTRACT
Water pumps are mostly used for supplying water to industries, commercial establishments, houses, hospitals, private residents, city water systems, agricultural irrigation, etc. Water pumping systems operated by three-phase induction motors reduce the Power Factor (PF) of the electrical network. To decrease the effect of poor PF, Power Factor Correction (PFC) circuits are added to the AC input side of the water pumping system to enhance the efficiency and PF of the system. This paper presents a Fuzzy Logic Controller (FLC) based modified Power Factor Correction Cuk Converter (PFCCC) operated Voltage Source Inverter (VSI) fed Brushless DC (BLDC) motor drive for agricultural water pumping applications. MATLAB/Simulink simulation results and experimental prototype model results are presented to validate the performance of the designed system.
