    Abstract: PROBLEM TO BE SOLVED: To obtain a part of a minimum surface to a fixed maximum current by checking a thyristor type part. SOLUTION: An auxiliary thyristor 13 is a vertical thyristor, and a cathode corresponds to an N-type region N5 formed in a well likewise. A part of a region P4 between regions N4 and N5 is covered with an insulation gate G2 and regions N4-P4-N5 corresponds to an N-channel enhancement MOS transistor M. An IGBT 14 is made a multicellor part. When the surface of a rear is covered with a P-type layer P1, a vertical IGBT is formed, and a cathode corresponds to metallization formed on regions P6, N6 and an anode corresponds to a surface at a rear side of a part. For a cell corresponding to a well P6, conduction takes place starting from an anode A towards metallization which covers the source N6, and the region N5 and then towards the region N4 and a cathode K. Next, conduction of a thyristor is checked.

    Abstract: The invention concerns the control of thyristor-type semiconductor power components (Sw) powered by an alternating current network (VS). The control signal is a pulse (Ie). It is stored in the form of magnetic induction (B), positive or negative, in a core (T) made of ferromagnetic material. At each current alternation of the network, the interrogation of the magnetic state of the strand results in the presence, or not, of a control signal on the power device (Sw).
