MPPT(Maximum power point tracking) is used in photovoltaic systems to maximize the solar array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics. In this paper, new MPPT algorithm is proposed for the small satellite in LEO. As the proposed MPPT algorithm does not need any calculation of power by multiplication of voltage and current, it can be made by the simply analog circuit. In this study, the proposed MPPT algorithm is verified by the simulation and experimental in the many conditions that can change the characteristics of the solar array.
