In accordance with one embodiment, a contactless power transfer system is provided that comprises a stationary member including a power input configured to receive power at first voltage from a power supply. The system further includes a rotating member rotatably coupled to the stationary member and a rotary transformer. The rotary transformer has primary and secondary sides, with the primary side being disposed on the stationary member. The primary side has a primary winding that receives power at the first voltage from the power input. The secondary side is disposed on the rotating member and produces power at a second voltage. The secondary side has a rotating core and separate secondary sub-windings, each of which has forward and return paths that are circumferentially disposed about the rotating core. The forward and return paths of each of the sub-windings rotate proximate to, and are disposed a substantially equal distance from, the primary winding disposed on the stationary member.
A contactless power transfer system, comprising:
An x-ray scanning system, comprising:
The system of 16, further comprising an x-ray detector disposed on the rotating member and configured to receive x-rays from the x-ray source.
The system of 16, wherein the x-ray source constitutes a high-voltage (HV) component, the secondary side providing power at a high-voltage to the x-ray source.
The system of 16, wherein the rotating core includes an E-shaped cross-section divided into at least two arcuate sections, each of the sub-windings being wrapped about a separate and corresponding one of the arcuate sections.
The system of 16, further comprising separate signal conditioning modules, each of which is joined to output leads of a corresponding one of the sub-windings, the signal conditioning modules being disposed evenly about and located on the rotating member.
The system of 16, wherein each of the sub-windings has corresponding sub-winding output leads that output power at a low voltage, the low voltage being less than the second voltage, at which power is output from the secondary side.
The system of 16, wherein each of the sub-windings has corresponding sub-winding output leads that output power, the power from the sub-winding output leads being combined to form a high voltage power output by the secondary side.
The system of 16, wherein each of the sub-windings has corresponding sub-winding output leads that output power, the power from one of the sub-windings constituting the power output by the secondary side at the second voltage.
The system of 16, further comprising separate rectifier circuits disposed on, and distributed about, the rotating member, the separate rectifier circuits being joined to corresponding separate sub-windings.
The system of 16, further comprising separate rectifier circuits joined to each of the sub-windings.
The system of 16, wherein the gantry is configured to receive one of a human or animal patient and the x-ray source is configured to perform a CT scan.
The system of 16, wherein the gantry is configured to receive luggage and the x-ray source is configured to perform baggage scanning.
The system of 16, wherein the x-ray source represents a high-voltage component, the system further comprising low-voltage detectors provided on the rotating member, the secondary side providing separate high-voltage and low-voltage power outputs to the x-ray source and the detector.
An x-ray generator comprising:
