Abstract:
In an electric power steering device, if a semiconductor switching element is used between a battery and a bridge circuit for opening and closing a current path, this arises a problem of generation of heat by an ON resistance; for this reason, a current flowing through the semiconductor switching element is limited if a difference between the gate voltage and the source voltage of the semiconductor switching element is smaller than or equal to a predetermined value.
