A circuit arrangement for producing high voltages.

摘要

In a circuit arrangement for producing high voltages by means of a voltage multiplier (6) composed of rectifiers (4) and capacitors (5) and fed from an alternating current source (7). a low amplitude voltage lying at the high voltage level is produced by means of the ripple voltage across one or more of the component parts of the voltage multiplier, the average potential of which does not differ substantially from the high voltage. In the case of an X-ray tube the total filament circuit may in this case 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.
