Inductor Current Sensing Peak-Power-Tracking Solar Array Regulator

The peak-power-tracking solar array regulator sensing the inductor current is proposed. Since it uses the inductor current as the solar array output power information, the PPT control scheme can be greatly simplified. The charge controlled two-loop scheme is presented to improve the dynamics due to the interaction between the inductor current and the PPT loop. The comparison between the single-voltage loop controlled system and the two-loop controlled system employing the charge control is presented.
