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).
