Abstract
1362153 Controlling inverters and D.C.-D.C. converters SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 27 Feb 1973 [16 May 1972] 9559/73 Heading H2F [Also in Division G3] In an inverter comprising a pair of electronic switches such as transistors T 7 , T 8 , driven by duration-modulated pulses (from M) via gates P 1 , P 2 , and in which the output is regulated by rectification at D 3 , D 4 and comparison at NC with a reference Vr, a pair of optical couplers OC 1 , OC 2 is included in the regulating loop to isolate the control circuit from the inverter. As described, capacitor C is charged via a constant current source G and repetitively discharged at the frequency of a clock source TM so as to generate a sawtooth signal. Comparator CM changes state at each transition of the sawtooth with the error voltage from comparator NC. The resulting pulses are duration-modulated in dependence on the error and passed by NAND gates P 1 , P 2 (alternately enabled by a bi-stable FF) to optical couplers OC 1 , OC 2 and transistors T 5 , T 6 to trigger the inverting transistors T 7 , T 8 . Rectified outputs are derived from RF 1 , RF 2 .
