Дослідження стійкості та чутливості елементів автоматики на базі L-, C-негатронів

Abstract

The thesis deals with the stability and sensitivity of elements of automatics on the basis of L-, C-negatrons. The energy properties of L-, C-negatrons are investigated in the work, that has allowed to define interrelation between a kind of fluxcurrent, charge-voltage characteristics and the equivalent circuits of L-, C-negatrons. Conditions of stability and possible modes of operation of loaded L-, C-negatrons Nand S-types are determined. Sensitivity of electronic circuits with L-, C-negatrons is determined. It is shown, that L-, C-negatrons are multipurpose elements which use allows to improve characteristics of elements of automatics. The dynamic negatrons on the basis of bipolar and field transistors in circuits with common emitter and common source are investigated. Oscillatory contours with L-, C-negatrons are investigated. A number of elements of automatics on the basis of L-, C-negatrons (inductive and capacitor sensors which have the sensitivity at 20-40 time more in comparison to prototypes; broadband high-frequency analog keys on C-negatrons) are developed and investigated.
