Abstract

Abstract With the continuous decrease of the cost of solar cells, there is an increasing interest in photovoltaic (PV) system applications. Electric motors powered by solar-cell generators are one of the most important applications, such as in water pumping systems. This paper investigates a photovoltaic-electro mechanic chain, composed of a PV generator, an impedance adapter DC–DC converter, a storage battery and a vector controlled induction machine. The PV generator is forced to operate at its maximum power point by using an appropriate search algorithm, and a balance between battery charge and motor supply is also ensured in all insolation conditions. Simulation results show the effectiveness and feasibility of such an approach.
