<P>PROBLEM TO BE SOLVED: To provide a device for controlling a power supply system which improves the reliability of a converter by detecting abnormal conditions of a current sensor for detecting a current flowing in a reactor of the converter without adding components. <P>SOLUTION: The power supply system 20 includes an energy storage device 28, a battery current sensor 11 for detecting a current flowing through the energy storage device 28, the converter 12 having a reactor L1, and a reactor current sensor 18 for detecting a current flowing to the reactor L1. The control device 30 includes a current control unit 220 for adjusting a current flowing to the reactor L1 to a target current to be detected by feedback control, a drive command generating unit 230 for generating a drive command of the converter 12 on the basis of the control output of the current control unit 220, and a sensor monitor 280 configured to detect the abnormal conditions of the reactor current sensor 18 on the basis of comparison between a current detecting value detected by the battery current sensor 11 and a current detecting value detected by the reactor current sensor 18. <P>COPYRIGHT: (C)2011,JPO&INPIT |
