<p><span style="font-size: 14px;">从目前国内的<a href="http://www.chenfeipower.com/"><strong>高频变压?/strong></a>产品来看，没有用扁铜带做的。如果使用扁铜带，需要做的很扁很扁，这个在制造工艺上来说是非常难的，否则在高频状态下，导体的涡流损耗将会非常大。目前高频基本都是采用利兹线，从而避免高频下的涡流损耗?br />
<br />
<br />
<br />
看磁芯大小与电流大小的对比关系确定使用利兹线还是铜带。电流不大用利兹线，大电流用铜带?br />
<br />
利兹线的优点是，相对铜带，工艺简?缺点是如果电流太大，需要的利兹线股数太多，工艺成本可能比铜带还高?br />
<br />
设计铜带和设计利兹线类似，先确定是多大的电流，根据温升要求，确定电流密度，电流除以电流密度得出需要的截面积，再按截面积计算需要的线材。区别是，利兹线的截面积是多个圆之和，铜带是矩形?br />
<br />
<br />
铜带相对利兹?br />
<br />
优点:非常适合用在一两圈的绕组上,空间利用率高,漏感?耐大电流<br />
<br />
缺点:成本?不适合多圈?通用性不?工艺难度?br />
<br />
计算: 长乘高就是面?等价于所有利兹线截面积之?br />
<br />
<br />
扁铜带不能用在高频，因为频率太高，趋肤效应会更加明显，且绕线十分不便。有点是适用于大电流。而利兹线则相反。高频有优势，且绕线方便。但是大电流时容易出现过载?br />
<br />
