Title: Improved circuit arrangements for producing energy pulses

Filed: 1950-03-06
Abstract: 680,573. Pulse generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd., WELCH, D. F., and RANDALL, K. B. Feb. 21, 1951 [March 6, 1950], No. 5597/50. Class 40 (vi). [Also in Group XXVII] In a pulse generating circuit of the type in which a capacitor is periodicially charged from a voltage source and then discharged through a spark-gap, the spark-gap is set to break-down at a voltage greater than that at which discharge of the capacitor is required. The break-down of the gap at the required lower voltage is effected by an auxiliary gap which when fired causes an oscillatory voltage to be added to that across the main gap to effect its breakdown. The Figure shows a pulse generator in which a capacitor C1 is charged from a voltage source and is periodically discharged via a main gap G1 into a load P. The break-down voltage of gap G1 is set so that it is above that at which capacitor C1 is required to discharge, but auxiliary gap G2 is set to break-down at the required limiting voltage of capacitor C1. When gap G2 fires there is an oscillatory discharge of current through capacitor C2 and inductor L2 so that the voltage at the junction of L2 and C2 rises above that of capacitor C1 and gap G1 fires to discharge capacitor C1 via load P. The generator may be synchronized by employing a triggered gap G2 which is fired under the control of an external pulse train. The charging circuit for capacitor C1 may be as described in Specification 644,347, [Group XXVII].
