Abstract

A microcomputer stores an offset correction value for correcting an offset of a detected current along with a pulse shift for each of a detected current of a maximum phase to which power is supplied for the longest time among three phases and a detected current of a minimum phase to which power is supplied for the shortest time among the three phases, and corrects the detected current of each of the phases with use of the stored offset correction values for the detected current of the maximum phase and the detected current of the minimum phase.
