Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a traveling wave tube integrated power supply. Background technique [0002] Microwave power modules with high power density are widely used in modern electronic countermeasures, satellite communications and active phased arrays. Among them, the traveling wave tube is the core device of the microwave power module. The traveling wave tube needs multiple power supplies to cooperate with the power supply to work normally. This multiple power supply is collectively called the traveling wave tube power supply. The traveling wave tube power supply generally includes a filament power supply, a cathode power supply, an anode power supply, a grid power supply, and collector power supplies. [0003] Traditional TWT power supply design schemes include independent power supply parallel power supply scheme and series power supply scheme. Since independent power supply is used to suppl...

AI Technical Summary

Problems solved by technology

However, the use of multiple independent power supplies makes the isolation design between power supplies complex and bulky, which cannot meet the miniaturization application requirements in the fields of vehicle transmitters and airborne decoy bombs.

[0004] Usually, in order to reduce the size of the traveling wave tube power supply, the method of sharing a converter is adopted. Due to the extremely high driving voltage required by the traveling wave tube, the lack of heat dissipation and high-voltage insulation technology limits the further miniaturization of the traveling wave tube power supply, resulting in The traveling wave tube power supply occupies about three-quarters of the volume of the microwave power module, which still cannot meet the development needs of modern electronic warfare electronic decoys and active phased arrays.
