proximity effect in flyback
Can anyone explain me what does the proximity effect depends on ? (in flyback transformer) As far as i know it has the influence on Rac/Rdc ratio in the windings. I made 50W flyback SMPS; it works very well, windings temperature is about 57 C. It is acceptable value, although i'd like to calculate copper losses more precisely than using only RMS currents and known windings resistance (skin effect is neglible in my case). I suppose that proximity effect has a great influence on copper losses
