Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
71 words
A voltage multiplier comprising a plurality of series-connected diodes and a plurality of capacitors coupled to the diodes, the capacitors being arranged in two separate capacitor winding rolls; wherein the rolls are arranged side-by-side with their axes coaxially aligned, the diodes comprising wire lead means serving as lead-out wires from the capacitor electrodes to the respective diodes; whereby the need for extra connections intermediate the electrodes and the diodes is eliminated.
Claim 2
Dependent Claim
71 words
A voltage multiplier comprising a plurality of series-connected diodes and a plurality of capacitors coupled to the diodes, the capacitors being arranged in two separate capacitor winding rolls; wherein the rolls are arranged side-by-side with their axes coaxially aligned, the diodes comprising wire lead means serving as lead-out wires from the capacitor electrodes to the respective diodes; whereby the need for extra connections intermediate the electrodes and the diodes is eliminated.
Claim 3
Dependent Claim
19 words
A voltage multiplier as claimed in claim 1 wherein the two winding rolls are arranged on a common former.
Claim 4
Dependent Claim
29 words
A voltage multiplier as claimed in claim 1 wherein the dielectric material used for the capacitor rolls comprises at least one polystyrene film and at least one polyester film.
Claim 5
Dependent Claim
15 words
A voltage multiplier as claimed in claim 1, further comprising an epoxy resin encapsulation material.
Claim 6
Independent Claim
91 words
A method of manufacturing a voltage multiplier of the type comprising a plurality of series-connected diodes and a plurality of capacitors connected to the diodes; the method comprising the steps of winding the capacitors in two separate winding rolls side by side on a common axis, and at appropriate respective stages in the winding process eliminating the need for connections intermediate the electrodes and the diodes by arranging each diode in turn so that each of its leads contacts a capacitor electrode in a respective one of the two winding rolls.
Claim 7
Independent Claim
91 words
A method of manufacturing a voltage multiplier of the type comprising a plurality of series-connected diodes and a plurality of capacitors connected to the diodes; the method comprising the steps of winding the capacitors in two separate winding rolls side by side on a common axis, and at appropriate respective stages in the winding process eliminating the need for connections intermediate the electrodes and the diodes by arranging each diode in turn so that each of its leads contacts a capacitor electrode in a respective one of the two winding rolls.
Claim 8
Dependent Claim
17 words
A method according to claim 5 wherein the winding of the two capacitor rolls is effected simultaneously.
Claim 9
Dependent Claim
33 words
A method according to claim 5, wherein the capacitor dielectric is wound in the form of heat-shrinkable film, the method including the further step of heating the wound assembly to shrink said film.
Claim 10
Dependent Claim
26 words
A method according to claim 5, wherein the dielectric material used for the capacitors comprises at least one polyester film and at least one polystyrene film.
