Abstract

La présente invention concerne un système de cellules solaires pour véhicules et un procédé de commande correspondant. Même quand un changement de courant électrique produit à partir d'une cellule solaire est élevé, les dispositifs à tension variable et les dispositifs à tension constante répartissent sélectivement le courant électrique à destination du courant électrique sans changement de tension. Ainsi, l'efficacité énergétique peut être améliorée, le nombre des composants peut être réduit sans utiliser de transformateur, et les pertes de conversion d'énergie peuvent être diminuées. De plus, le courant électrique produit à partir de la cellule solaire sert à la ventilation, la purification de l'air, le froid et le chaud, et des dispositifs de commodité d'un véhicule. Ainsi, un conducteur peut jouir d'un environnement contrôlé quand il circule dans le véhicule. Il en résulte que la présente invention peut répondre aux aspirations du conducteur pour l'utilisation de dispositifs de commodité et assurer un environnement intérieur confortable.
