Abstract

A flyback EHT- and sawtoothcurrent-generator using a transformer and switching means connected thereto which conduct during a scan period and do not conduct during a flyback period, and partly parasitic reactances connected to the transformer. During the flyback period the generator has at least two resonant frequencies so chosen that a substantially oscillation-free scan is produced and during the scan it has at least one resonant frequency which is approximately equal to an integral multiple of the reciprocal value of the duration of the scan period.
