Inhibitable static switch for an AC electric circuit including an inductive load

摘要

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.
