Abstract:
(EN) Relays (SMR1, SMR2) are inserted between a battery (BA) and a step-up converter (12A), and relays (SR1, SR2) are inserted between a battery (BB) and a step-up converter (12B). A controller (30) controls control signals (CONT1-CONT4) for controlling open/close of the relays (SMR1, SMR2, SR1, SR2). Upon occurrence of short circuit failure of a switching element in the step-up converter (12A, 12B), the controller (30) controls turn-off of the relays (SMR1, SMR2, SR1, SR2) such that at least one of the turn-off order or timing of the relays is changed depending on the switching element in which short circuit failure has occurred.
(FR) Selon l'invention, des relais (SMR1, SMR2) sont introduits entre une batterie (BA) et un transformateur élévateur de tension (12A), et des relais (SR1, SR2) sont introduits entre une batterie (BB) et un transformateur élévateur de tension (12B). Un dispositif de commande (30) commande des signaux de commande (CONT1-CONT4) pour commander l'ouverture/la fermeture des relais (SMR1, SMR2, SR1, SR2). Lors de l'apparition d'une défaillance de court-circuit d'un élément de commutation dans le transformateur élévateur de tension (12A, 12B), le dispositif de commande (30) commande la coupure des relais (SMR1, SMR2, SR1, SR2) de telle sorte qu'au moins l'une parmi l'instruction de coupure ou la temporisation de coupure des relais est modifiée, en fonction de l'élément de commutation dans lequel la défaillance de court-circuit s'est produite.
(JA)  リレー(SMR1,SMR2)は、バッテリ(BA)と昇圧コンバータ(12A)との間に介挿接続され、リレー(SR1,SR2)は、バッテリ(BB)と昇圧コンバータ(12B)との間には、リレー(SMR1,SMR2)が介挿接続される。制御装置(30)は、リレー(SMR1,SMR2、SR1,SR2)の開閉を制御する制御信号(CONT1~CONT4)を制御する。制御装置(30)は、昇圧コンバータ(12A,12B)でスイッチング素子の短絡故障が発生すると、いずれのスイッチング素子が短絡故障したかに応じて、リレーのオフ順序およびオフタイミングのうちの少なくとも一方を変化させるように、リレー(SMR1,SMR2,SR1,SR2)のオフを制御する。
