Abstract
1,113,302. Semi-conductor switching circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. 17 May, 1966 [18 May, 1965], No. 20885/65. Heading H3T. A circuit for switching a pulse of either polarity through a ferrite phase shifter comprises a pair of thyristors A, B and a pair of capacitors C A , C B . Firing thyristor A discharges capacitor C A and charges capacitor C B , both currents flowing through the load. The firing pulses may be derived from a transformer as shown, or from a transistor circuit, Fig. 4 (not shown). In this latter arrangement a transistor (T 4 ) is provided to prevent the two S.C.R.s from shorting the supply if both are accidentally fired together.
