Abstract
Device for the generation and regulation of high intensity currents, especially welding currents, by means of the phase section with a primary circuit and a secondary circuit connected through a transformer, characterized in that the primary circuit contains an antiparallel connection of two thyristors, which in parallel with this antiparallel connection is an inductance and by which means are provided that during a short circuit on the secondary side and during the connection displace the phase of the ignition pulses.
