Abstract
(EN) A series/parallel switching unit (20) switches between integrating a plurality of output systems of a plurality of power generating DC power supplies into a single output system where the plurality of DC power supplies are connected in series then connecting to a power conditioner (210), or integrating the plurality of DC power supplies into a single output system where the plurality of DC power supplies are connected in parallel then connecting to a storage battery via a charging/discharging circuit (120). The series/parallel switching unit (20) comprises a plurality of destination switching relays corresponding to the plurality of output systems, and state detection relays for detecting the connection states of the plurality of destination switching relays. The plurality of destination switching relays and the state detection relays are driven by common coils.
(FR) La présente invention concerne une unité de commutation en série/en parallèle (20) effectuant une commutation entre l'intégration d'une pluralité de systèmes de sortie d'une pluralité d'alimentations en courant continu de production de courant dans un seul système de sortie dans lequel la pluralité d'alimentations en courant continu sont connectées en série, puis la connexion à un conditionneur d'alimentation (210), ou l'intégration de la pluralité d'alimentations en courant continu dans un seul système de sortie dans lequel la pluralité d'alimentations en courant continu sont connectées en parallèle, puis la connexion à un accumulateur par le biais d'un circuit de charge/décharge (120). L'unité de commutation en série/en parallèle (20) comprend une pluralité de relais de commutation de destination correspondant à la pluralité de systèmes de sortie, et des relais de détection d'état destinés à détecter les états de connexion de la pluralité de relais de commutation de destination. La pluralité de relais de commutation de destination et les relais de détection d'état sont excités par des bobines communes.
