Abstract
A high voltage transformer comprising a secondary winding composed of coils which are wound one on top of the other and which are electrically interconnected by diodes which are connected in the same rectifying sense. Each coil consists of a number of series connected sub-coils, each of which consists of a first layer of turns which contact each other, and a second layer which comprises a smaller number of turns. The first layers of two successive subcoils directly contact each other, whereas the second layers are separated by a clearance having a width equal to the wire thickness.
Claims8
A high voltage transformer, comprising a ferromagnetic core, at least one primary winding and one secondary winding disposed on said core with said secondary winding comprising a series of wire-wound coils, each of which is wound on the preceding coil and is separated therefrom by an insulating layer, every two successive coils being electrically connected by a diode with all diodes being connected in the same rectifying sense, and wherein each coil of the series of coils forming the secondary winding includes a number of series-connected sub-coils each of which comprises a first layer comprising a number of turns which contact each other over at least a part of their length and a second layer which comprises a smaller number of turns wound directly on the first layer, the first layers of every two successive sub-coils directly contacting each other whereas the second layers are separated from each other by a clearance space whose width approximately equals the thickness of the wire.
A high voltage transformer comprising, a ferromagnetic core, a plurality of diodes, a primary winding and a secondary winding disposed on said core with the secondary winding comprising a plurality of wire-wound coils alternately connected in series with said plurality of diodes such that any two successive coils are interconnected by a diode, all of the diodes being connected serially with the same polarity and each of the coils being wound on a preceding coil and separated therefrom by an insulating layer, and wherein said coils of the secondary winding comprise a plurality of series connected sub-coils each of which includes a first axially extending layer comprising a number of turns in contact with each other over a part of their length and a second axially extending layer comprising a smaller number of turns wound directly on the first layer, the first layers of successive sub-coils contacting each other and the second layers thereof being separated from each other by a clearance space approximately equal to the thickness of the wire.
