Abstract


This research describes a cost-effective BLDC motor-driven solar photovoltaic (PV) water pumping system. We're working with a dual stage power conversion here with this solar PV water pump setup. To get the most power out of a solar PV array, the duty ratio of a DC-DC boost converter is adjusted at the first stage. By adjusting the motor speed, the DC bus voltage is kept at a constant level. This regulation reduces motor losses due to the drop in motor currents at a higher voltage for the same power injection as a result of this regulation. Using an INC-based maximum power point tracking (MPPT) control method, the duty ratio can be controlled. Models and simulations of the proposed system's performance have been done in great detail. The speed sensor/encoder is no longer necessary with scalar control. Motor current sensors are also no longer required. An additional speed feed forward term in the control scheme enhances the dynamics even further. The pump's constant variation is not a problem for the proposed control method. BLDC motors, which are more efficient and quieter than DC motors, are used in our suggested system. Maximum PV generator power loss is well matched to the BLDC motor's load characteristics. Analyzed are the MATLAB/SIMULINK results for several DC-DC converter topologies.
