 Title Three-Phase Commutation Choke, connected before rectifier bridge with smoothing choke Input Set inductance at peak current (View the peak value on the current diagram) Select the AC inductance : L-Type = 2 Select Cu round wire: Wire = 0 The frequency of the first harmonic is 50Hz Set the rms values of harmonics of the thermal current: typical values In=I1/n, without 3rd and 9th harmonic Set the temperature rise Select grain oriented steel. Note that the induction will be optimized by program in order to get optimal relationship between core losses and winding losses Set Gap = 1 and Core Assembly = 2 or better Select suitable 3 phase core family
 Output Control the value of induction, gap and connected wires in parallel Test Round the number of turns Note In order to calibrate the choke, connect it on the calculated calibration 3 phase AC-voltages (rms value) with the calibration frequency (normally 50Hz or 60Hz) and then vary the gap until you get the calculated calibration 3 phase AC-currents (rms value).
 Title One-Phase Commutation Choke, connected before rectifier bridge with smoothing choke Input Set inductance at peak current (View the peak value on the current diagram) Select the AC inductance : L-Type = 2 Select Cu round wire: Wire = 0 The frequency of the first harmonic is 60Hz Set the rms values of harmonics of the thermal current: typical values In=I1/n Set the temperature rise Select grain oriented steel. Note that the induction will be optimized by program in order to get optimal relationship between core losses and winding losses Set Gap = 1 and Core Assembly = 2 or better Select suitable one phase core family
 Output Control the value of induction, gap and connected wires in parallel Test Round the number of turns 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).
