Filed: 1974-11-22
Abstract: 1484286 Switching circuits COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 22 Nov 1974 [23 Nov 1973] 50686/74 Heading H3T In a circuit for gating a periodic signal to a transformer, the gating signal is delayed so as to occur about the middle of a half-cycle of the signal thereby preventing saturation of the transformer during the first half-cycle. Clock pulses in antiphase applied to terminals P1, P2 gated by transistors T3, T4 to outputs B1, B2 in response to a negative signal applied at EC. Once EC has gone negative, thyristor Th will turn on as soon as P1 is positive, drawing current through R4 and R5. When P2 goes positive capacitor Cd will start to charge and the circuit values are chosen so that about half way through the positive pulse on P2 reciprocally coupled transistor T1 and T2 turn on. This puts a positive signal on CA which opens gates T3, T4. The pulses on outputs B1, B2 are connected by transistors (TC1, TC2), Fig. 1 (not shown), to the primary windings of a transformer the secondary of which provides the circuit output.
