Title:
POWER SUPPLY DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2018196234
Kind Code:
A
Abstract:
To stably supply power to a second load while suppressing the influence of power supply to a first load, and to replenish power from a power supply path side corresponding to the second load to a power supply path side corresponding to the first load when a predetermined abnormal state occurs.SOLUTION: A power supply device 1 for a vehicle comprises: a first power supply circuit 10 for converting a voltage applied to a first conductive path 41, and for applying the voltage to a second conductive path 42; and second power supply circuits 20A, 20N for converting the voltage applied to the first conductive path 41, and for applying the voltage to third conductive paths 43A, 43N. Switch parts 51A, 51n are provided between the third conductive paths 43A, 43N and the second conductive path 42. Control parts 22A, 22N set the switch parts 51A, 51N to an off-state when at least either the first power supply 10 or the second conductive path 42 is not in a predetermined abnormal state, and set the switch parts 51A, 51N to an on-state when it is in the predetermined abnormal state.SELECTED DRAWING: Figure 1
