Abstract: A drive system for driving an AC electric machine includes an electric machine power converter that provides a primary current excitation vector having a magnitude and angle to drive the AC electric machine. A control system separate from or incorporated into the power converter causes the power converter to inject a carrier signal to the AC electric machine that is superimposed onto the current vector and that generates a carrier response signal that has sensitivity to magnetic alignment information of the AC electric machine at its operating point, the carrier response signal providing a measurable magnetic alignment signature of the AC electric machine. The control system causes the power converter to inject the carrier signal at an injection angle between a constant flux injection angle and a constant torque injection angle, to reduce noise and/or vibration of the AC electric machine caused by the injected carrier signal.

Abstract: A magnetic unit is presented. The magnetic unit includes a magnetic core. The magnetic core includes a first limb and a second limb disposed proximate to the first limb, where a gap is formed between the first limb and the second limb. The magnetic unit further includes a first winding wound on the first limb. Moreover, the magnetic unit includes a conductive element disposed facing an outer periphery of the first winding, where the conductive element is configured to control a fringing flux generated at the gap. Further, the magnetic unit includes a heat sink operatively coupled to the conductive element, where the conductive element is further configured to transfer heat from at least one of the conductive element and the first winding to the heat sink. Moreover, a high frequency power conversion system and a method of operation of the magnetic unit is also presented.

Abstract: A system and method for position sensorless control of an AC electric machine is disclosed. A drive system for driving an AC electric machine provides a primary current excitation to drive the AC electric machine, the primary current excitation comprising a current vector having a magnitude and angle. The drive system injects a carrier signal to the AC electric machine that is superimposed onto the current vector, with the carrier signal being selected to generate a carrier response signal that has sensitivity to magnetic alignment information of the AC electric machine at its operating point. The drive system measures at least one magnetic alignment signature of the AC electric machine from the generated carrier response signal and controls an orientation of the current vector using the measured at least one magnetic alignment signature, so as to achieve a desired magnetic operation of the AC electric machine.
