초록

In this paper, the simple analog MPPT (Maximum Power Point Tracking) algorithm is proposed for the solar array of KOMPSAT (Korea Multi-Purpose Satellite). This method doesn't need any calculation of power by multiplication of voltage and current and a measurement of the solar array temperature. It is consist of only two sample and hold circuits, two comparators, a flip-flop, and an integrator. The proposed MPPT algorithm is verified by the simulation for the 100[W] solar array.
