Abstract

1,104,855. Transistor switching circuits; pulse generating circuits. ETABLISSEMENTS MERLIN & GERIN S.A. 14 May, 1965 [25 June, 1964], No. 20402/65. Headings H3P and H3T. [Also in Division F1] A gate turn off (G.T.O.) semi-conductor device is turned off when switch C is opened causing a negative trigger pulse to be emitted from the secondary S of pulse transformer T and is turned on when switch C is closed so that energy stored within the transformer T causes a current i 2 to flow and produce a positive pulse at the secondary S. A diode D, which limits the amplitude of the positive-going pulse and avoids overloading or destruction of the G.T.O. device, connects the primary P via a resistor R2 to a D.C. supply. The switch contact C may be a mechanical or static element.
