Voltage Multiplier with Integrated Metalized Capacitor Network

A newly developed voltage multiplier which generates high voltage for cathode-ray tubes embodies, in addition to silicon diodes, an integrated network of some 30 000 self-healing capacitors arranged in parallel and in series. This network is sawed by means of a special technique from a large ring-shaped mother capacitor into rectangular blocks. The principal advantages of this method of fabrication are, first, that the internal series circuit results in relatively low field strength in the region of the electrode edges and, second, that the dissipation of self-healing energy due to dielectric breakdowns is limited. These advantages, together with the easy handling of the precise geometric configurations, have made it possible to implement a new device in which small cubic volume and extremely low voltage drops during self-healing are accompanied by excellent reliability.
