output filters for frequency converters

Purpose and application

Ouput filters are intended for suppression of high-frequency harmonics of carrier frequency of three-phase output voltage of switchboards with frequency control.

Output filter is connected up between switchboard's output and step-up transformer. Filter's rated curent circuit should be corresponding with rated output curent of the switchboard.

Functional capabilities

Output filters for frequency converters for rated current 160...1200А. Coefficient of current and voltage harmonicity curve distortion:

   No filter:

      K_Uoutp= 46%
      К_Ioutp= 19%

   Filter:

      K_Uoutp, К_Ioutp= not more than 5%
