<p>An EHT power supply, for example for a cathode ray tube, having a voltage multiplier of a multi-stage Cockroft-Walton type, in which the capacitors of each stage are formed by layers of conducting material (13a, 13b) juxtaposed on either side of a layer (12) of dielectric material, the layers of dielectric material forming an integral part of the mechanical structure of the multiplier and physically supporting the rectifier diodes of the multiplier. In one embodiment of the invention, the multiplier is formed as a closely-spaced stack in which each stage comprises a separate layer (12) of dielectric material, and in another embodiment the capacitors of the AC side of the multiplier are formed on one layer (8) of material and the capacitors of the DC side of the multiplier are formed on another layer (9), the two layers being disposable on opposite sides of the neck (10) of a cathode ray tube with the successive stages being longitudinally disposed along the neck.</p> |
