摘要:
One or more techniques and/or systems described herein provide a shielded power coupling device, such as may be used to transfer electric power from a stator portion of a computed tomography (CT) apparatus to a rotor portion. The shielded power coupling device comprises a rotor portion and a stator portion, separated by an airgap, respectively comprising one or more windings and a core. The shielded power coupling device further comprises a fringe field mitigation element(s) (e.g., an electrically conductive wire) that is configured to carry an induced current that creates a magnetic field that mitigates, or substantially cancels, magnetic flux generated by current in the windings that escapes from the core near the core airgap.
