Title: Combined filter inductor and hall current sensor

Abstract: A combined filter inductor and Hall current sensor for a double inverter motor drive is formed on a unitary magnetic core. The magnetic core has a suitable winding and air gap to comprise an inductor. The Hall effect sensor is situated in the airgap to detect a Hall effect voltage created by the magnetic flux in the air gap.
