Abstract

A semiconductor device for controlling a three-phase motor with double windings, includes a first inverter that drives a first winding of the three-phase motor, a second inverter that drives a second winding of the three-phase motor and a communication line between the first and second inverters. The first and second inverters, through the communication line, notify a respective operation state each other.
