Abstract: A radiation generator comprising a radiation source, a high voltage tank assembly to energize the radiation source and a power circuit configured to supply alternating current (AC) power to the high voltage tank assembly is provided. The high voltage tank assembly comprises a voltage multiplier assembly configured to include a printed circuit board comprising multiple slots, plurality of electrical components configured to be mounted on the printed circuit board and at least one insulating cover with multiple projections configured to be placed on one of the first surface and the second surface of the printed circuit board. Further, the projections of the insulating cover are configured to fit into the slots of the printed circuit board. The projections when fitted into the slots provide insulation barrier to the electrical components mounted on the printed circuit board.

Abstract: Methods and arrangements for reducing partial discharges on a printed circuit board are provided. A method of reducing partial discharge in a printed circuit board includes providing a conducting surface coupled to a component under at least one of electrical and thermal stress, wherein the conducting surface is a metallic plate.

Abstract: The present invention provides an in-line filament transformer for a vacuum device. The filament transformer comprises: a core; a primary winding and a secondary winding wound around the core, wherein the secondary winding is biased at a high voltage and the primary winding is placed in line with the secondary winding; and a shield for shielding the primary winding. In an embodiment, the transformer comprises a bobbin for incorporating primary winding and secondary winding. An arrangement of increasing creepage distance is incorporated in the bobbin by providing plurality of sections on the bobbin. The invention also provides a shield in the primary section of the bobbin for shielding the primary winding from the secondary winding. In an embodiment the shield is in the form of shield winding of thin wires wound in a defined manner.
