Abstract
A high voltage rectifier with provisions for rapidly limiting or discontinuing the current flow in response to the occurrence of overcurrents and rapidly restoring such current when the overcurrents cease. The rectifier comprises one or more stages, each stage comprising a rectifier fed from a secondary transformer winding, a subsequent smoothing capacitor, a first switch serving as a direct D.C. converter for regulation of the output voltage, a choke and capacitor for smoothing the current and a second switch, activated by overcurrents, such that the smoothing chokes can be switched over by the second switch into a first recovery circuit wherein, prior to each switching off of the respective second switch the associated first switch is switched on for a predetermined period of time and then switched off.
