摘要： The present invention is directed to an apparatus for supplying power to a rotatable x-ray tube for generation of an x-ray beam for acquisition of CT data. The apparatus includes a slip ring to transfer power from a stationary inverter to a rotatable HV tank. The HV tank conditions the transferred power and creates a voltage potential across the x-ray tube for x-ray generation. The inverter has a single or pair of series resonant circuits connected either directly to the slip ring or indirectly through a transformer to limit frequency content and reduce common-mode component of the voltage and current waveforms carried by the slip ring as well as reduce power losses.

摘要： A transformer is provided comprising a first member upon which a first circuit is wound; a second member upon which a second circuit is wound such that power is transferred to the second circuit in a contact-less manner; and a signal transmitter on the first member in close proximity to an appropriate receiver on the second member together with a signal transmitter on the second member in close proximity to an appropriate receiver on the first member such that said transmitters and receivers exchange signals in a contact-less manner, whereby the circuits are embedded in a high thermal conductivity resin. An exemplary embodiment of the invented transformer is one where the second member rotates relative to the first member.
