Abstract: Control device for the electromagnet coil of a switching apparatus, comprising a MOS transistor switch (12) in series with the coil (B), a double alternation rectifier (11) supplying the coil, a signal regenerator having a closed-loop control circuit (13) connected to a current reading element in the coil and providing to the switch a control signal having a call level and a hold level, and a voltage reducing circuit (14) connected to the direct terminals of the coil. The closed-loop control circuit (13) is connected to the MOS transistor grid and holds the current (IB) of the coil to a level independent of the source voltage.

Abstract: The apparatus according to the invention comprises a power part (20) provided with a power switch having two controlled semiconductors (TH1, TH2) of which the power terminals are connected to an alternating source in series with the load, a control circuit (30) for controlling said switch and which comprises a first control switch sensitive to an input signal and connected to the trigger (G1, G2) of the power semiconductors (TH1, TH2) via a rectifier bridge (33). The control switch is a field effect transistor (I1) of which the drain-source path is connected to the continuous terminals (31, 32) of the rectifier bridge (33) via a current limiter (L). To the grid (G) of the transistor (I1) is applied a control signal formed as a function of an input signal presented at the terminals (36, 37) of a galvanic isolation member (38). The apparatus according to the invention may be used as a unipolar or multipolar static contactor or relay for alternating currents.
