摘要：

This paper presents a technique to improve the performance of a photovoltaic (PV) powered permanent magnet dc motor coupled to a screw-type volumetric water pump. The method uses a solid state Electrical Array Reconfiguration Controller (EARC), which senses the radiation as low, medium or high. Accordingly, the controller chooses one favorable set of I-V characteristics for starting and another favorable set of I-V characteristics for steady state operation. This is done by switching the solar panels, depending upon the starting current requirements and the irradiance level, from a parallel to series-parallel to series connection. This produces sufficient starting current especially at low and medium radiation levels, which considerably improves the pump's performance, particularly in the early morning, late evening and cloudy days, providing valuable extra pumping hours for the user. © 1990 IEEE
