Efficient Single Stage Photovoltaic Pumping System Using BLDC Motor With Grid Power Export

Abstract

This paper proposes an efficient single-stage photovoltaic (PV) fed permanent magnet brushless DC (PMBLDC) motor water pumping system with grid power interface. The power conditioning system used in the conventional two-stage system is eliminated, and the maximum power point tracking (MPPT) scheme is incorporated within the inverter used for the electronic commutation of the BLDC motor. The BLDC motor pumping is advantageous than the conventional induction motor-aided water pumps. The proposed system is the first of its kind to employ a grid power export scheme utilizing the same inverter drive which in turn reduces the complexity of adding new inverter circuitry and thereby making the system economically viable. The BLDC pump and grid power export scheme is realized in both simulation and hardware environment for a power rating of 1 kW. The results reveal that the proposed system is highly viable.
