MICROWAVE UNIT Russian patent published in 2020 - IPC H05B6/64 

FIELD: electrical engineering.

SUBSTANCE: invention is related to the field of electric engineering and is used in super-high frequency (SHF) heating units. SHF apparatus comprises N (even number) of magnetrons with series-connected diodes to anode circuits, high-voltage and filament supply transformers. Magnetrons are connected to each other by common points of cathodes and filaments, magnetrons are divided into pairs and in each pair second filament caps are connected to different leads of one winding of filament supply transformer, anodes of magnetrons are isolated from the housing of the plant and through the above diodes are connected to outputs of N secondary windings of the high-voltage transformer, and second outputs of these windings are combined with common point of cathodes and filaments. In the second version, magnetrons are connected to each other by common points of cathodes and filaments, second filament caps are connected to one terminal of filament supply transformer winding, anodes of magnetrons are isolated from the housing of the plant and through the above diodes are connected to outputs of N secondary windings of the high-voltage transformer, and second outputs of these windings are combined with common point of cathodes and filaments.

EFFECT: disclosed is microwave installation.
