In the TIDM-1000 schematic, the inductance value of PFC inductor (53PR116-292) L2/L4/L5 is 2mH, with a peak current of approximately 15A. According to the inductance energy storage formula L * I * I=450mH.A.A。 If using iron silicon aluminum magnetic rings, the 77102 grade should be used, and the outer diameter of the 77102 magnetic ring is 103mm. If using ferrite magnetic cores, the volume will be even larger. But your actual PFC inductance is not that large(only 53mm), why is that?
Also, could you please let me know how many turns there are in the coil?
