Abstract
1371411 Thyristor pulse circuits DRESSER INDUSTRIES Inc 28 July 1972 [28 July 1971] 35496/72 Heading H3T An S.C.R. pulse generator has a cathode impedance which is varied in response to the output pulse in such a manner as to ensure that the S.C.R. does not latch on. S.C.R. 57 is fired by each pulse from oscillator circuit 50 to produce a high voltage pulse in the secondary of an output-transformer. The pulse is fed back to a transistor 63 by a transformer 60, 62 and after a time the feedback is insufficient to maintain the transistor conducting and accordingly the S.C.R. extinguishes. If the input pulse is still present the S.C.R. will refire. Transistor 63 may be of F.E.T. type or may be replaced by an S.C.R. The output pulses may be fed to a voltage multiplier supplying pulses and a D.C. to an ion tube (Fig. 1, not shown).
