Abstract

1,203,955. Transistor switching circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 28 Oct., 1968 [22 Nov., 1967],No. 53221/67. Heading H3T. [Also in Division H2] A control circuit for triggering a plurality of electronic switches T1 . . . T4 comprises: a number of stages each comprising a pair of capacitors C 1 C 5 , C 2 C 6 , C 3 C 7 , C 4 C 8 , to isolate each stage from the next; a separate transformer TR1, TR2, TR3, TR4 for each stage; and a resistor R1 . . . R4 coupled between the primary and secondary of each transformer respectively. The transformers (P 1 , P 2 , P 3 ) may be connected in series as shown, or in parallel, Fig. 3 (not shown). Overload cutouts may be provided, Fig. 4 (not shown), and twin input windings may be used on the transformers to minimize surges.
