Test and analysis of a photovoltaic DC-motor pumping system

FPGA Controlled Power Conditioning System for Solar PV Fed PMDC Motor

“…Further, Four-Quadrant PWM converter driving the PMDC motor [5], optimization of system efficiencies [6], novel multi-input DC boost converter for brushless DC motor (BLDC) fed by photovoltaic (PV) array [7], design and performance analysis of a DC PV water pumping system in absence of battery and inverter [8], stand-alone PV water pumping system without battery [9][10][11], an induction-motor-pump fed by a PV generator and field-oriented control [12], low solar DC voltage comprises DC-AC converter with high-frequency DC-DC stage and machine-pump [13], PV water-pump control system based on digital signal processor [14] were investigated and documented in existing studies. Lot of computational efforts, issues related to memory usage for calculations, A/D and D/A conversions, clock frequencies of used controller and dynamic control are the major pitfalls of these aforementioned studies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. These shortcomings and inabilities, motivates the researchers to develop a holistic technique to reduce these inconsistencies.…”

“…Generally, dc [1][2][3][4][5][6][7][8] and ac [9][10][11][12][13][14] powered water pumping systems fed by solar power, using various MPPT algorithms implemented in different controllers were reported in literatures. Variation of solar irradiation and average temperature has been investigated in [4] for the proper sizing of solar water pumping systems with more accuracy.…”

“…of electrical power and shortage of water existing, specially, in villages [1][2][3][4][5][6]. The significant efforts were made by the researchers to develop a solar based pumping system using, semiconductor technology [5,[10][11][12]15].…”
