摘要：

The maximum solar power tracking and energy utilization of a stand-alone photovoltaic array (PVA) feeding a chopper controlled permanent magnet DC motor drive scheme is studied. A computer controlled model of the PVA including the effects of temperature and solar irradiation changes was developed and used in both digital simulation and laboratory implementation. The electrical load applied voltage was controlled by a MOSFET type-A chopper using either proportional integral or fuzzy logic based controllers so that the maximum available solar power of the PVA is always tracked for all varying ambient temperature and solar irradiation levels, as well as for any small variations of the electrical load. The dynamic performance of the overall system was studied and satisfactory results were obtained using both types of controller.
