Enhanced solar water-pumping system driven by a synchronous reluctance motor

A self-reliant, economically-affordable and maximum-efficiency solar water pumping system is proposed in this paper. The autonomy is achieved powering the system through a PV source which well fits for remote or isolated applications. The costs are reduced by removing the DC-DC voltage converter usually present in these applications. The efficiency is enhanced by using a Synchronous Reluctance motor that directly control the pump speed through a Maximum Power Point Tracking algorithm. The paper includes novel implementation hints and a batch of experimental results that prove the effectiveness of the proposal
