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 () providing different propagating delays to a physical quantity proportional to the power image, a comparator () of the outputs of the delaying elements to control a trigger () supplying a signal (Q) with two automatic control states to a static power converter, and means () for detecting a transitory operating condition from variations in oscillations of an established operating condition and means () for modifying the delay input by the slower delaying element ().
