Document Type and Number:
Japanese Patent JP7281712
Kind Code:
B2
Abstract:
To improve accuracy of failure detection for a converter.SOLUTION: An on-vehicle power source system includes: a first converter 14 and a second converter 15 which are connected in parallel between an input portion 12 and an output portion 13, and evenly share an output power during a normal operation; an external signal input portion 16; and a control portion 17 which detects a voltage of the output portion 13, the temperature of the first converter 14, the temperature of the second converter 15, and a signal of the external signal input portion 16, and controls the operations of the first converter 14 and the second converter 15. When receiving the signal from the external signal input portion 16, the control portion 17 causes the first converter 14 and the second converter 15 to start to thereby output a predetermined voltage to the output portion 13 over a first period, and after completion of the first period, the control portion 17 determines failure of the first converter 14 or the second converter 15 based on the temperature difference between the first converter 14 and the second converter 15.SELECTED DRAWING: Figure 1
