摘要
The present invention, when all the gates of the switching elements in the block are a drive circuit, an electric device that generates counter-electromotive force The present invention relates to an apparatus and method for determining whether a malfunction is present in the drive circuit for driving. After the gates are blocked, the temperature of the switching elements is monitored, the presence of a malfunction is determined based on the detected temperature of the switching element. When the detected temperature is above a predetermined temperature; When the amount of change in the detected temperature is more than a predetermined value; Or the rate of change of the detected temperature is determined that a malfunction is present, when more than a predetermined rate. Accordingly, it is possible to determine whether the gates in the drive circuit are appropriately blocked as appropriate, the influence of the malfunction of any of the other components of the drive circuit the outside can be minimized.
