COMMANDE D'UN CONVERTISSEUR DE PUISSANCE POUR UNE RECHERCHE AUTOMATIQUE DU POINT DE PUISSANCE MAXIMALE

摘要

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 ).
