中文摘要	An intelligent control system for photovoltaic lighting systems was developed to enhance the photovoltaic lighting system efficiency and prolonging the lighting time through intelligent control. Maximum power point tracking technology (MPPT) and a precise charging control strategy was used with a variable switching frequency and a constant-power control strategy. A single-state inverter was used in the lighting circuit to enhance the system energy transformation efficiency and lower the cost. Experimental results show that the control strategy significantly enhances the performance of the photovoltaic lighting system with the high pressure sodium lamps with system efficiencies above 90%.
