Description
Выводы а, в, с трансформаторов 1 и 2 подключаютс к фазам трехфазной сети. Напр жени со вторичных обмоток 5 и 6 ограничиваютс двухсторонними амплитудными ограничител ми 7 и 8 и при помощи балластных резисторов 9 и 10 суммируютс на входе фильтра 11. При этом на входе фильтра получаетс напр жение квазитреугольной формы, амплитуда которого определ етс величиной напр жени ограничени двухсторонних амплитудных ограничителей 7 и 8. Фильтр 11 выдел ет первую гармонику выходного напр жени .Terminals a, b, from transformers 1 and 2 are connected to the phases of a three-phase network. The voltages from the secondary windings 5 and 6 are limited by two-way amplitude limiters 7 and 8 and summed at ballast resistors 9 and 10 at the input of the filter 11. At the same time, a quasi-triangular voltage is obtained at the input of the filter; amplitude limiters 7 and 8. Filter 11 selects the first harmonic of the output voltage.
Применение двух однофазных трансформаторов выгодно отличает предлагаемый источник эталонного синусоидального напр жени от известного, так как при этом упрощаетс источник, уменьшаютс его габариты и потребл ема мощность.The use of two single-phase transformers favorably distinguishes the proposed source of the reference sinusoidal voltage from the known one, since it simplifies the source, reduces its dimensions and consumes power.
