Title
(EN) SYSTEM FOR THE ELECTRONIC MANAGEMENT OF PHOTOVOLTAIC CELLS AS A FUNCTION OF METEOROLOGY
(FR) SYSTEME DE GESTION ELECTRONIQUE DE CELLULES PHOTOVOLTAIQUES FONCTION DE LA METEOROLOGIE
Abstract
(EN)
The invention relates to a system for the electronic management of a photovoltaic generator, said system comprising a plurality of n static converters (11, 12, 13) connected in parallel, each converter (11, 12, 13) being electrically connected to at least one photovoltaic cell (10) of the generator. The number of converters connected is varied by varying the photovoltaic power, by comparing the generated power to thresholds P1, P2,..., Pn-1 after a time delay t. The invention also relates to a generator comprising said system and to the associated control method.
