最近和一個(gè)美國(guó)的工程師討論了一下 趨膚效應(yīng), 他告訴我不用考慮趨膚效應(yīng)對(duì)溫升的影響,他們做過實(shí)驗(yàn)的, 請(qǐng)問有人做過此實(shí)驗(yàn)嗎,結(jié)果怎樣??

我貼上他的E-email供參考:
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.)
