Title

One-Step Power Factor Correction Choke, connected before rectifier bridge with switching transistor, diode and RC-Load

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:
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 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).
