Description

(1) Technical field:

[0001] The invention relates to an intermediate frequency generator, in particular to a medium and high power integral salient pole type intermediate frequency brushless excitation synchronous generator. (2) Background technology:

[0002] At present, there is an increasing demand for intermediate frequency generators in the market. For example, national defense facilities and related fields of the national economy require intermediate frequency power supplies, airports need mobile intermediate frequency power supplies for maintenance and repair of warehouse equipment and equipment, and industrial smelting needs. Intermediate frequency power supply of 400Hz and higher, etc.

[0003] Existing intermediate frequency power sources are often obtained by frequency conversion of industrial frequency power sources. The frequency of power frequency power, that is, ordinary generators, is generally 50HZ or 60HZ. In order to obtain intermediate frequency power, variable ...
