This paper proposes a simple, cost-effective, and efficient brushless dc (BLDC) motor drive for solar photovoltaic (SPV) array-fed water pumping system. A zeta converter is utilized to extract the maximum available power from the SPV array. The proposed control algorithm eliminates phase current sensors and adapts a fundamental frequency switching of the voltage source inverter (VSI), thus avoiding...
This paper deals with the development of a simple, cost-effective, efficient, reliable and eco-friendly water pumping system utilizing a DC-DC boost converter as an intermediate power conditioning unit in solar photovoltaic (SPV) array fed brushless DC (BLDC) motor driven water pump. The power optimization of SPV array and limiting starting inrush current of the BLDC motor are two major functions...
This paper aims at the design of solar photovoltaic (SPV) array fed buck-boost converter based water pumping system utilizing a switched reluctance motor (SRM) drive.

A boost-buck (BB) DC-DC converter is proposed for solar photovoltaic (SPV) array fed water pumping system using a permanent magnet brushless DC (BLDC) motor drive. To design a BB converter with suitable voltage control, DC-DC boost and buck converters are cascaded such that it accomplishes the purpose of maximum power point tracking (MPPT) and soft starting of the BLDC motor. The BB converter exhibits...
This paper deals with the application of a single ended primary inductor converter (SEPIC) in solar photovoltaic (SPV) array fed water pumping system. A permanent magnet brushless DC (BLDC) motor is employed to drive a centrifugal pump coupled to its shaft. Soft starting of the BLDC motor is achieved by controlling the SEPIC through the incremental conductance maximum power point tracking (INC-MPPT)...
Solar photovoltaic (SPV) array based water pumping is receiving wide attention now a days because the everlasting solar energy is the best alternative to the conventional energy sources. This paper deals with the utilization of a buck-boost converter in solar PV array based water pumping as an intermediate DC-DC converter between a solar PV array and a voltage source inverter (VSI) in order to achieve...
This paper deals with the solar photovoltaic (SPV) array fed water-pumping system using a Luo converter as an intermediate DC-DC converter and a permanent magnet brushless DC (BLDC) motor to drive a centrifugal water pump. Among the different types of DC-DC converters, an elementary Luo converter is selected in order to extract the maximum power available from the SPV array and for safe starting of...
