Abstract

1,208,794. Semi-conductor devices. ALLMANNA SVENSKA ELEKTRISKA A.B. 14 March, 1968 [16 March, 1967], No. 12317/68. Heading H1K. The control circuit of a thyristor having a plurality of control electrodes 11, 13 comprises a control device 2, to supply ignition pulses, connected between a main electrode 12 and a central control electrode 11, and a capacitor 4 connected between the main electrode 12 and the other, peripheral, control electrodes 13 so that there is a long current path between the control device and the capacitor connections. In this way the high resistance of the base layer to which the control electrodes 13 are connected prevents the capacitor from loading the control device to any significant extent after ignition.
