Abstract

Abstract A compact high voltage power supply includes a high voltage transformer 4 with individual concentric secondaries S1, 52,..., connected to form a ladder network with two series-connected assemblies of diode rectifiers R and R' respectively located on corresponding sides of the transformer winding. Next-adjacent secondaries S1, S2,..., are wound from the same side of the winding space but in an opposite winding sense, and each secondary comprises an odd plurality of layers. This provides a high voltage transformer arrangement without cross-connection of the diodes in which the peak and alternating voltages across the interwinding insulation is optimally reduced and the smoothing effect of stray capacities is enhanced.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 125 words
A high voltage power supply including a transformer and rectifier assembly in which the high-voltage secondary of the transformer comprises a plurality of concentric individual windings and each end of each secondary winding is connected via a respective rectifier to a corresponding end of the next adjacent winding or to a high voltage supply connection so that the assembly provides a full wave rectified output, characterised in that next-adjacent windings are wound in the opposite winding sense starting from the same side of the winding, that each winding comprises an odd plurality of winding layers, and that for each pair of next adjacent windings each rectifier is connected to the ends of the respective adjacent windings, which lie on the same side of the windings.
Claim 2
Dependent Claim 125 words
A high voltage power supply including a transformer and rectifier assembly in which the high-voltage secondary of the transformer comprises a plurality of concentric individual windings and each end of each secondary winding is connected via a respective rectifier to a corresponding end of the next adjacent winding or to a high voltage supply connection so that the assembly provides a full wave rectified output, characterised in that next-adjacent windings are wound in the opposite winding sense starting from the same side of the winding, that each winding comprises an odd plurality of winding layers, and that for each pair of next adjacent windings each rectifier is connected to the ends of the respective adjacent windings, which lie on the same side of the windings.
Claim 3
Dependent Claim 53 words
A power supply as claimed in Claim 1, characterised in that an inductively open-circuit layer of electrically conductive foil is disposed adjacent the inner surface of the innermost secondary winding and electrically connected to that high voltage supply conductor to which the ends of said innermost secondary winding are connected via respective rectifiers.
Claim 4
Dependent Claim 56 words
A power supply as claimed in Claim 1 or Claim 2, characterised in that an inductively open-circuit layer of electrically conductive foil is disposed adjacent the outer surface of the outermost secondary winding, and electrically connected to that high voltage supply conductor to which the ends of said outermost secondary winding are connected via respective rectifiers.
Claim 5
Dependent Claim 44 words
A power supply as claimed in any one of the preceding claims, characterised in that successive said secondary windings of larger diameter are made smaller in width so as to present substantially the same magnitude of conductive surface area to the next adjacent winding.
Claim 6
Dependent Claim 30 words
A power supply as claimed in any one of the preceding claims, characterised in that the high voltage secondary of the transformer comprises an even number of individual secondary windings.
Claim 7
Dependent Claim 26 words
A high voltage power supply including a transformer and rectifier assembly substantially as herein described with reference to Figures 6,7,8,9,10 and 11 of the accompanying drawings.
Claim 8
Dependent Claim 26 words
A high voltage power supply including a transformer and rectifier assembly substantially as herein described with reference to Figures 6,7,8,9,10 and 11 of the accompanying drawings.
