Abstract
In a circuit arrangement for producing high voltages by means of a voltage multiplier with rectifiers and capacitors and fed from an alternating current source in which circuit arrangement, a low amplitude voltage lying at the high voltage level is produced by the ripple voltage across one or more of the component parts of the voltage multiplier, the average potential of which component part (s) does not differ substantially from the high voltage. In the case of an X-ray tube high voltage supply the total filament circuit may be approximately on the high cathode voltage and no severe requirements for insulation need to be fulfilled. The ripple voltage may be used to produce other small amplitude voltages lying at a high voltage level.
Claims8
A circuit arrangement comprising:
- a voltage multiplier;
- an alternating current source feeding said voltage multiplier;
- and
- means for supplying a small amplitude voltage with respect to the voltage multiplier high voltage, obtained from a ripple voltage across a component part of said voltage multiplier with an average potential not differing substantially from the high voltage to a utilizing circuit connected to said voltage multiplier.
