Abstract
A system for transferring maximum power from a solar cell array by loading the array in a manner which forces it to operate at its maximum power point. The system samples the open circuit voltage of the solar cell array to provide a signal proportional to the voltage of the array at its maximum power point. The sampled open circuit voltage is compared to the operating voltage of the solar cell array to provide an error signal which is proportional to the difference between the maximum power point voltage and the operating voltage of the array. The amount of power transferred from the array to a load is altered in accordance with the error signal to operate the array at its maximum power point.
