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
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
