STEP-UP CONVERTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/059336
Kind Code:
A1
Abstract:
The present invention confirms an abnormality if, with regard to respective current detectors, a provisional determination of abnormality has been sustained over a confirmation period. In such a case, the confirmation period is set: so as to be shorter the greater the absolute value of a detection value of a current detector that has not made a provisional determination of abnormality; or so as to be shorter the greater the absolute value of a target current of a reactor corresponding to a current detector that has not made a provisional determination of abnormality; or so as to be shorter the greater the absolute value of an estimated current of a reactor corresponding to a current detector that has made a provisional determination of abnormality, which is estimated on the basis of a current of either a power storage device or a load and a detection value of a current detector that has not made a provisional determination of abnormality.
