ABSTRACT:
The invention relates to switching circuits using fast rectifier diodes. To damp the oscillations liable to occur at the time when the fast diode passes from a conducting state into a blocked state, a supplementary diode with a lower blocking speed and a smaller current passage cross-section than the fast diode is positioned in parallel on the latter and with the same polarity. Application to cut off power supplies, undulators, converters, etc.
