Abstract
The pilot circuit comprises an R-C network consisting of a condenser inserted between a gate terminal of the MOS transistor and ground and a resistance for charging said condenser. In parallel with the resistance there is placed an SCR circuit with associated threshold circuit which permits firing of the SCR circuit when the charge voltage of the condenser reaches a preset threshold.
