Description

Предметом насто щего изобретени   вл етс  устройство дл  усилени  электрических колебаний при помощи тиратрона, включенного и работающего по способу, описанному в основном авт. св. № 48583.The object of the present invention is a device for amplifying electrical oscillations with the help of a thyratron switched on and operating according to the method described mainly by the author. St. No. 48583.

St., active resistance is included, from which the increased voltage fluctuations are removed.

На фиг. 1 изображено устройство дл  получени  пилообразных напр жений на емкости С при помощи тиратрона Т, включенного последовательно с колебательным контуром LC; одновременно это же устройство может быть использовано дл  усилени  по току.FIG. 1 shows an apparatus for producing sawtooth voltages on capacitance C using a thyratron T connected in series with an oscillatory circuit LC; at the same time, the same device can be used for current amplification.

При изменении напр жени  на сетке тиратрона измен етс  средн   сила тока в анодной цепи тиратрона. Обозначив через К отнощение приращени  напр жени  на аноде тиратрона к приращению напр жени  на сетке в момент зажигани  АУ и полага  отношение частоты пилообразных колебаний к собственной частоте контура достаточно больщими , можно приближенно выразить приращение средней силы тока Д/о в зависимости от AVWhen the voltage on the grid of the thyratron changes, the average current in the anode circuit of the thyratron changes. By denoting the ratio of the voltage increment at the anode of the thyratron to the voltage increment on the grid at the time of ignition of the AC, and assuming that the frequency of the sawtooth oscillations to the natural frequency of the circuit is large enough, we can approximately express the increment of the average amperage D / o depending on AV

Д/а где R - омическое сопротивление контура.Where R is the ohmic resistance of the circuit.

На фиг. 2 изображено устройство дл  усилени  колебаний по напр жению , в котором по сравнению с фиг. 1 введено дополнительное сопротивление Ra, с которого снимаетс  усиленное напр жение.FIG. 2 shows a device for amplifying voltage oscillations, in which, as compared with FIG. 1, an additional resistance Ra has been introduced, from which the reinforced voltage is removed.
