Abstract
The invention concerns a method and a circuit for maximum power point tracking of a variable power source from a comparison of an image of the power (P) supplied by the power source, the circuit comprising two elements (14, 31) providing different propagating delays to a physical quantity proportional to the power image, a comparator (16) of the outputs of the delaying elements to control a trigger (17) supplying a signal (Q) with two automatic control states to a static power converter, and means (33) for detecting a transitory operating condition from variations in oscillations of an established operating condition and means (32) for modifying the delay input by the slower delaying element (31).
