Patent ID: 6984970

Claim:
A circuit for conditioning a power supply having a current-voltage characteristic that is an exponential function for which a graph of the power supplied as a function of the voltage at the terminals of said power supply features a maximum power point, said conditioning circuit comprising: a power cell with one input that is supplied with power by said power supply and one output that supplies power to a load, and a control circuit for controlling said power cell via a control signal applied to said power cell to slave the input voltage of said power cell, wherein said control circuit comprises: calculation means comprising means for receiving instantaneous measurements of points on said current-voltage characteristic and a program that determines said exponential function of said current-voltage characteristic on the basis of four points on said current-voltage characteristic and determines a reference voltage, and control means for supplying said control signal representative of the difference between the reference voltage calculated by said calculation means and an instantaneous voltage at the output of the power supply so as to cancel out said control signal.
