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).
