  • Circuit and apparatus for the protected supply of a load by means of static and electromechanical switches
    Patent number: 4888661
    Abstract: A circuit and apparatus are provided for the protected supply of a load using static and electromechanical switches. A switch apparatus having current limiting properties is opened by remote control means after a very short delay, following disabling of a static switch system placed in series therewith and connected in parallel across a voltage limiting component.

  • Inhibitable static switch for an AC electric circuit including an inductive load
    Patent number: 4782419
    Abstract: A static switch is provided for controlling the closing and opening of an AC electric circuit including an inductive load. This switch includes an inhibitable thyristor having an RCD network for protection against the voltage gradients on turn-off. The anode-cathode path of the inhibitable thyristor and its protection network are connected to the AC energy source through a full wave rectifier device, whereas a voltage clipping member is disposed at the terminals of the rectifying device.
