  • Abstract:
  • Renewable energy is the energy which comes from natural resources such as Sunlight, wind, rain, tides and geothermal heat etc. This paper proposes brushless DC (BLDC) motor drive for solar photovoltaic (SPV) array fed water pumping system using a zeta converter. Zeta converter is utilized in order to extract the maximum available power from the SPV array. There is no additional control or circuitry is used for speed control of the BLDC motor. The speed is controlled through a variable DC link voltage of VSI. An appropriate control of zeta converter through the incremental conductance maximum power point tracking (INC-MPPT) algorithm offers soft starting of the BLDC motor. The proposed water pumping system is designed and modeled such that the performance is not affected under dynamic conditions. The suitability of proposed system at practical operating conditions is demonstrated through simulation results using MATLAB/ Simulink.
