Abstract
En 中文
A fast and parameter-intensive maximum power point tracking (MPPT) technique is presented for a photovoltaic (PV) water pumping system, driven by the brushless dc motor (BLDCM). The technique is based on the application of ripple correlation control. As an advantage, rather than artificial signal injection, the proposed technique employs the inherent perturbations introduced due to phase commutation and nonsinusoidal back-EMF of BLDCM to determine the maximum power points of the PV system. The technique can be simply employed for different configurations of BLDCM-based PV water pumping systems. Experiments are performed to demonstrate the effectiveness of the proposed technique.
