SU35903A1 - Magnetron generator - Google Patents

Description

The proposed magnetron generator is shown in FIG. 1 and 2. In FIG. 1 M - magnetrons, the magnetization of which is carried out due to the magnetic field of the current of the heat, Ce-blocking capacitances, / -reactive coils in the anode circuit, D, -reactive coils in the magnetron heat chain (they can not be replaced by customized Lecher systems).

As can be seen from FIG. 2, the magnetrons are turned on in such a way that the glow of each subsequent pair is included in the previous current antinode, i.e., the glow of magnetrons, denoted by the letter Жз, turns on in the current antinode: the circuits of the magnetrons, marked by the letter MI and the glow of the magnetrons, denoted by the letter MI appears to be included in the antinode of the current contours; magnetrons, denoted by the letter MZ.

Thus, the slightest change in current /, in the circuits of magnetrons, marked with the letter Afi, will cause a change in current / 2 in the circuits, indicated by the letter MZ by the value of / i 5 (S-slope), which in turn will change the current in the circuits of the magnetrons, designated by the letter MI , by the value of / i S, etc., until fully exhausted. After this, the process is repeated in the opposite direction. From this reasoning it is clear that in the presented scheme

an oscillatory process is established, the period of which will be determined by the self-induction of the wires L connecting the magnetrons, denoted by the letter MI or MZ and the capacitance, both distributed along these wires and concentrated at their ends.

The feedback is carried out not only due to the difference in the vibrational potentials between the electrodes of the magnetrons, but also (mainly) due to the magnetic flux.

As can be seen from the diagram, the magnetic flux varies with the frequency of the circuit. In the circuit shown in FIG. 2 magnetrons, denoted by a single digit with letters, work in relation to each other with a phase shift of 180 °; phasing difference is achieved by changing the direction of the channel current.

The subject matter of the invention.

A magnetron generator with four magnetrons, characterized in that, in order to obtain feedback by automatically changing the magnetic flux with the natural frequency of the generator, two pairs of magnetrons are connected in such a way that the magnitude of the magnetrons M is included in the antinode current of the circuits of the magnetrons MI, and the magnitude of the magnetrons MI is included in the antinode current of the circuits of the magnetrons.
