C-core chokes

BV 29031002a and BV 3116002 and BV 2983043a


Fields of application


Line reactor, commutation reactor, smoothing reactor, PFC-choke, armature-circuit choke, intermediate circuit choke (direct link inductor), boost converter


Description


The size is determined by the energy E = 0,5 x L x I². All given values are calculated for low warming and low humming. With forced cooling smaller dimensions are possible. If there is only a bit of over temperature allowed, the dimensions will increase.

Chokes for one-phase consumers and electronic devices with the following advantages:

Use as a smoothing reactor or commutation reactor in DC circuits

  • low ripple factor
  • attenuation of current harmonics
  • bridging of line failures
  • limitation of current peaks

Use as line reactor

  • attenuation of current harmonics
  • limitation of start-up current
  • guarantee of short-circuit voltage of 4% to line

Use as PFC-reactor

  • reduction of harmonics

Use as an armature circuit reactor

  • reduction of harmonics in the motor and thus an increase of the motor efficiency at one-phase application
  • reduction of current noises in the motor
  • increase of the total inductance of the motor circuit for DC motors with low inductance

Use as intermediate circuit choke or boost converter with harmonics

  • Harmonics with high current stress can be absorbed very well,  because of the low-loss cut cores
