PROBLEM TO BE SOLVED: To enable a cut-off means to protect a control circuit and a booster circuit by preventing any abnormal current from flowing into the control circuit, the booster circuit, or their ground lines due to a failure that cannot be handled by fusion cutting of a high-capacity resulting from progress of electric erosion or glowing of a cracked part of a capacitor.SOLUTION: Power supply equipment for a vehicle comprises a case 38 mounted on a vehicle, a power supply means 2 mounted on the vehicle, a voltage conversion circuit 32 which is housed in the case 38 and connected to the power supply means 2, an electric component 9 connected to the voltage conversion circuit 32, a normally-opened switch 7 disposed between the voltage conversion circuit 32 and an a ground 6, a control circuit 31 which is housed in the case 38, is connected to the power supply means 2, and controls operation of the voltage conversion circuit 32, and the cut-off means 31 which electrically shuts off the ground 6c if current from the control circuit 31 to the ground 6 is at a predetermined value or higher.SELECTED DRAWING: Figure 1

    【課題】電蝕の進行やコンデンサのクラック部分のグロー化により、大容量ヒューズの溶断によって対応できない不具合が生じることに起因して、制御回路、昇圧回路、或いはこれらのアースライン等に何らかの異常電流が流れることを防いで制御回路や昇圧回路を保護することができる。【解決手段】車両に搭載されるケース38、車両に搭載される電源供給手段2、ケース38に収容され電源供給手段2に接続される電圧変換回路32、該電圧変換回路32に接続される電装部品9、電圧変換回路32と接地6との間に配置される常開スイッチ7、及びケース38に収容されるとともに電源供給手段2に接続され、電圧変換回路32の動作を制御する制御回路31、該制御回路31から接地6への電流が所定以上で接地6Cを電気的に遮断する遮断手段31を備えた。【選択図】図1
