Abstract : The development of a transistorized electronic switch is reported. The switch is intended for converting several slow-varying d-c voltages into proportional-amplitude pulses and combining these pulses for a common load. It is assumed that all N d-c voltage sources are independent and have an internal impedance of up to 100 kohms. The voltage may vary within 0.005--5 v. The switch comprises voltage-to-pulse converters K sub 1, K sub 2, K sub N, a clock-pulse generator G, a distributor that sends clock pulse to individual converters, and a matching circuit which combines the resulting pulses. An inverse-connected n-p-n Si transistor (P103) is used in the converter. The clock-pulse generator has a conventional blocking-generator circuit; its frequency varies by plus or minus 20% with temperature within -10 + 50C. The ferrite-transistor distributor circuit is equipped with a noise filter. The matching circuit includes a common-base stage and an emitter follower; the circuit was tested with 50 converters at -10 + 50C. (Author)
