Abstract: The invention concerns a control circuit for controlling a load to be supplied in alternating current voltage, comprising a two-way switch capable of being controlled by phase angle, in series with the load between two terminals applying the alternating current supply, and comprising, in parallel with the switch, a first resistive element, a first capacitor and an element, in series with the first resistive element and the first capacitor, and operating, in steady state conditions, as a constant current source, the midpoint of the association in series connection of the first resistive element and the first capacitor being connected, via an element with two-way conduction automatically triggered when the voltage at its terminals exceeds a predetermined threshold, to a terminal controlling the switch.

Abstract: 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.
