Title (EN) PROTECTIVE DEVICE AND POWER SOURCE SYSTEM
(FR) DISPOSITIF DE PROTECTION ET SYSTÈME DE SOURCE D’ALIMENTATION
(JA) 保護装置及び電源システム
Abstract:
(EN) In a protective device (5), fuses (52, 53, 54) are respectively provided to three current paths from a battery to respective loads (2, 3, 4). A microcomputer (51) outputs, to a synthesis circuit (50), pulse signals (P2, P3, P4) of which the pulse positions are different from one another. The pulse signals (P2, P3, P4) correspond to the fuses (52, 53, 54), respectively. The synthesis circuit (50) synthesizes a pulse signal corresponding to a fuse, among the fuses (52, 53, 54), of which voltage at the downstream end is lower than a threshold. The microcomputer (51) specifies a blown fuse on the basis of a synthesized signal (Pt) synthesized by the synthesis circuit (50).
(FR) Dans un dispositif de protection (5), des fusibles (52, 53, 54) sont respectivement disposés sur trois trajets de courant d’une batterie vers des charges respectives (2, 3, 4). Un micro-ordinateur (51) délivre en sortie, vers un circuit de synthèse (50), des signaux d’impulsion (P2, P3, P4) dont les positions d’impulsion sont différentes les unes des autres. Les signaux d’impulsion (P2, P3, P4) correspondent aux fusibles (52, 53, 54), respectivement. Le circuit de synthèse (50) synthétise un signal d’impulsion correspondant à un fusible, parmi les fusibles (52, 53, 54), dont la tension à l’extrémité aval est inférieure à un seuil. Le micro-ordinateur (51) spécifie un fusible fondu sur la base d’un signal synthétisé (Pt) synthétisé par le circuit de synthèse (50).
(JA) 保護装置(5)では、バッテリから負荷(2,3,4)夫々への3つの電流経路夫々にヒューズ(52,53,54)が設けられている。マイコン(51)は、パルスの位置が相互に異なるパルス信号(P2,P3,P4)を合成回路(50)に出力する。パルス信号(P2,P3,P4)夫々はヒューズ(52,53,54)夫々に対応する。合成回路(50)は、ヒューズ(52,53,54)の中で、下流側の一端の電圧が閾値未満であるヒューズに対応するパルス信号を合成する。マイコン(51)は、合成回路(50)が合成した合成信号(Pt)に基づいて、溶断されているヒューズを特定する。
