Abstract
(EN)
A collector plate (14) is connected to an output terminal (16). The collector. plate (14) is made such that heat capacity per unit area of a neighboring region (14A) thereof, which is near to a portion where the output terminal (16) is connected, is different to the heat capacity per unit area of other regions (14B, 14C). More specifically, the other regions (14B, 14C) are formed such that the heat capacity per unit area thereof is smaller than that of the neighboring region (14A).
(FR)
Une plaque collectrice (14) est connectée à une borne de sortie (16). La plaque collectrice (14) est faite de sorte que la capacité thermique par surface unitaire d'une région voisine (14A) de celle-ci, proche d'une partie branchement de la borne de sortie (16), est différente de la capacité thermique par surface unitaire d'autres régions (14B, 14C). Plus spécifiquement, les autres régions (14B, 14C) sont formées de sorte que leur capacité thermique par surface unitaire est inférieure à celle de la région voisine (14A).
