<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 on a reactor of the converter without adding components. <P>SOLUTION: The power supply system 20 includes an energy storage device 28, the converter 12 having the reactor L1, and the current sensor 18 for detecting a current flowing through the reactor L1, and supplies power to a load device 45 including motor generators MG1, MG2. A control device 30 of the power supply system 20 feedback-controls the converter 12 by generating a drive command of the converter 12 on the basis of a detected value of the current sensor 18, and detects the abnormal conditions of the current sensor 18 by comparing a change in current based on the detected value of the current sensor 18 during a predetermined period with a change in current as a reference obtained by computation on the basis of the state of the converter 12 during the predetermined period. <P>COPYRIGHT: (C)2011,JPO&INPIT |
