Abstract:
1. A power source device for an x-ray tube, comprising: a. a circuit board substantially surrounded by an enclosure; b. a high voltage component on the circuit board configured to have a higher voltage differential between this component and the enclosure than other components on the circuit board; c. a circuit on the circuit board configured to create a voltage differential between the high voltage component and the enclosure of at least 9 kilovolts; d. an electrically insulative potting material disposed between the circuit board and the enclosure; e. a layer of electrically conductive material disposed within the potting material and disposed at least partially between the circuit board and the enclosure; f. the layer of electrically conductive material dividing at least a portion of the potting into separate and discrete sections, the separate and discrete sections of potting having a higher dielectric strength than if the sections of potting were not divided by the layer of electrically conductive material; g. the separate and discrete sections of potting providing electrical insulation between the high voltage component and the enclosure; and h. the layer of electrically conductive material is configured to have a voltage applied that is between a voltage of the high voltage component and a voltage of the enclosure.
