SU22745A1 - Stabilized Cathode Generator - Google Patents

Description

The present invention relates to a device for a stabilized cathode generator and consists in a special form of its implementation.

The drawing shows a skeme generator.

The self-induction coil of the circuit B of the contact lamp B is inductively coupled to the oscillatory circuit of the driving oscillator A. A constant negative bias voltage is applied to the grid of this lamp through the resistance r, which is under the resulting voltage of the two contact detectors a, b. Detectors a and b are included in the Ci and Cz circuits, with the Cz circuit being tuned to a frequency lower than the generated frequency, and the Q circuit tuned symmetrically to a frequency greater than the frequency of the driving oscillator A. With a small range of the distance between circuits Q and 62 - the connection between circuit C and circuit A is weak; with a larger range, the coupling increases. Changing the frequency in the circuit A. in the direction of reduced "will cause an increase in negative voltage on the grid of the lamp Si and a decrease in the magnetic field of circuit A, which will cause the restoration of the initial setting. Changing the generator frequency upwards will reduce the negative potential of the grid of the lamp, increase the magnetic field of the generator circuit, and again bring the tuning back to its original position. Frequency stabilization will be accompanied by oscillations of the power of the master oscillator (an increase in frequency will increase power, a decrease will decrease it), therefore it is necessary to compensate for these oscillations, which can be achieved by connecting a powerful constant small impedance amplifier G connected to the circuit of a BI lamp through a potentiometer R, Providing the ability to balance power pulsations. The stabilizer can be easily attached to any generator with independent excitation.

Subject invented.

A stabilized cathode generator, characterized by the use of two contact detectors, one of which is included in circuit C, associated with the oscillatory circuit of master oscillator A and tuned to a frequency greater than that generated, and the other in circuit Co, also associated with the oscillatory circuit of generator L but tuned to a frequency lower than the generated one, the midpoint of which circuits C, C- is connected to the middle plate of the three-lining capacitor, the other two plates of which are connected to the detectors, the midpoint of which is connected to the grid circuit of the cathode lamp, circuit B, which is also connected by a magnetic flux with the oscillatory circuit of generator A, with the goal that, as the generated frequency changes,

the bias voltage across the grid of the lamp shunting circuit B, and thereby changing the mode of operation of generator A so that changes in the generated frequency are reduced.
