Title

Swinging Smoothing Choke for 3 Phase Rectifier Bridge

Input

·         Set two LI-points: 2 inductance at 2 peak currents. Note that the induction corresponds to the first current

·         Select the differential inductance : L-Type = 4

·         Select Cu flat wire: Wire = 4

·         The frequency of the first harmonic is 300Hz

·         Set the harmonics of the thermal current: the rms-values of the first harmonic and of the DC-current

·         Set the temperature rise

·         Select cheap steel. Note that the induction will be optimized by program in order to get 2 prescribed inductance at 2 prescribed currents

·         Set Gap = 1 and Core Assembly = 2

·         Select  suitable core family

Output

·         Press Ctrl+L in order see the diagram Inductance vs. Current

Test

·         Round the number of turns

·         Change the peak value of the second LI-point in order to increase the current range of the diagram Inductance vs. Current

Note

·         In order to calibrate the choke, connect it on the calculated calibration AC-voltage (rms value) with the calibration frequency (normally 50Hz or 60Hz) and then vary the gap until you get the calculated calibration AC-current (rms value).

Title

Smoothing Choke for 1 Phase Rectifier Bridge
