摘要：
The present invention relates to a device for controlling a composite bridge including two anode-gate thyristors, the cathodes of which are connected together to a positive output terminal, the gates of the two thyristors being interconnected. The device includes a single-throw switch, controllable to be turned off and on, connected on the one hand to the two thyristors and on the other hand to a reference potential, and control means to turn on the switch only in a predetermined voltage range around the zero voltage of an a.c. voltage of the composite bridge.
