Analysis and design of the inductor-current-sensing peak-power-tracking solar-array regulator

An analysis and design of a peak-power-tracking solar-array regulator that senses the inductor current are proposed. Because it uses the inductor current as the solar-array output-power information, the peak-power-tracking control scheme can he greatly simplified, The charge-controlled two-loop scheme is presented to improve the undesired dynamics caused by the interaction between the inductor current and the peak-power-tracking loop. The comparison between the single-voltage-loop-controlled system and the two-loop-controlled system that uses the charge control is presented.
