Abstract(in English) When the solar array is used as an input power source, the optimum operating point tracker is often employed to exploit more effectively the solar array as an electric power source and to obtain the maximum electric power. Usually, the optimum operating point is determined by computing the feed power of the solar array power supply with a microcomputer, DSP and so forth. However, such a method has the problems of the complex control circuit configuration, high cost and low control speed. From this viewpoint, this paper proposed a new optimum operating point tracker of the solar cell power supply system, in which inexpensive pn-junction diodes are used to generate the reference voltage of the operating point of the solar array. Using the proposed method, the comparatively high degree of the solar array optimum point tracking performance is obtained, even when the light intensity and environmental temperature of the solar array are varied.
