Abstract: 1,089,797. Pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 8, 1964 [July 9, 1963], No. 27173/63. Headings H3P and H3T. In a pulse generator of the type in which a pulse forming network PFN is charged through an inductor L and then discharged through a load R under control of a switching device S so as to generate a pulse, the pulse amplitude is stabilized by diverting energy from the charging inductor L into a resistive circuit (e.g. R3) under control of a switching device (e.g. thyratron V1) when the PFN is charged above a predetermined voltage. The thyratron S, V1 may be replaced by semi-conductor controlled rectifiers and the latter may be controlled by a trigger circuit TU coupled to it via a transformer. The resistor R3 may be of voltagedependent material and may be shunted by a capacitor or, as in Fig. 4 (not shown), a capacitor may be connected between the junction of R3 and the H.T. line so as to return the surplus energy to the supply.
