Abstract
The invention relates to a circuit arrangement for the simultaneous ignition of a plurality of thyristors. Control paths of the thyristors are each connected to a secondary winding of a pulse transformer by way of a separate full-wave rectifier, an alternating current of higher frequency being supplied to the primary winding of the pulse transformer by a control current amplifier. In order to obtain a continuous flow of control current when a control signal is given, it is provided, according to the invention, that there is connected to the control path of each thyristor the series arrangement of a storage reactance coil and an uncontrolled diode poled in the direction of the gate current, and that the output of the full-wave rectifier is connected to this uncontrolled diode.
