Shielded power coupling device e.g. computed tomography scanner for medical applications, has shielding to inductive coupling efficiency increasing element when operated beyond predetermined power levels

摘要

An inductive coupling field receiving element converts an inductive coupling field to electric power. An inductive coupling efficiency increasing element increases coupling between an inductive field generating element and the inductive field receiving unit. A shielding on the periphery of the inductive coupling efficiency increasing element is capable of eliminating leakage of electromagnetic radiation when it is operated at power levels exceeding 2.5 kW. Independent claims are included for the following: (1) method for transferring electric power between stationary subsystem and rotatable subsystem; (2) flux-aligning core set for use with windings and shields; (3) passage-containing core segment; and (4) system including shielded inductive power coupling device.
