ABSTRACT:
For a power system having a single maximum power point and varying loads, the present invention provides a power regulator which adjusts the operating point of one source as a function of only the sensed current conditions of the secondary source.
In the preferred embodiment, a solar array is controlled by a regulator which determines whether the battery is properly charging. Upon the occurrence of an undercharging condition, the array operating point is adjusted so as to minimize undercharge current. Upon the occurrence of a charging condition, the operating point is adjusted so as to continue battery charging according to predetermined limits.
