Abstract

PURPOSE:To enable detection of abnormality in a fuse provided on each arm by detecting abnormality in the array of a pulse signal from means of generating pulses. CONSTITUTION:A means 7 for generating rising or falling pulses is provided for the current flowing through a rectifier circuit 1 for feeding a DC power to a load 3 rectifying alternate currents U, V and W while detecting the current. Abnormality in the array of a pulse signal is detected with an abnormality detector 9 by feeding the signal from the means. This enables detection of an abnormal signal for a fuse provided on each arm composing a bridge of the rectifier circuit at abnormality in the array of the pulse signal.
