最近和一个美国的工程师讨论了一下 趋肤效应, 他告诉我不用考虑趋肤效应对温升的影响,他们做过实验的, 请问有人做过此实验吗,结果怎样??
我贴上他的E-email供参考:
An experiment was performed to determine if skin effect is an issue. The result was that skin effect is not an issue so the multi-strand wire will not help.( Note: the experiment was to measure temperature rise during actual operation with the actual high frequency waveforms and compare that to the temperature rise of the inductors with the same RMS value of DC current pumped through them with a DC power supply. There was no significant difference in temperature rise that couldn’t be accounted for.)
