功率电感绕组高频损耗计算的一种方法

A method for calculating the high frequency loss of power inductors

在Dowell驿高频功率电感绕组损耗理论分析与验证的基础上，讨论了高频功率电感在电流为三角波时绕组损耗的一种计算方法；以连续工作模式的BUCK转换器中使用的高频功率电感为例进行说明。本计算方法仅考虑由趋附效应与邻近效应引起的电感绕组高频损耗，未考虑由漏磁通引起的涡流损耗。

Dowell of high-frequency power inductor winding loss theory analysis and verification based on, discuss the high frequency power inductor in current for triangular wave winding losses of a calculation method; used in continuous mode of Buck Converter in high frequency power inductor as an example is described. This method only considers the caused by the skin effect and proximity effect of inductance winding loss at high frequency, the eddy current loss caused by the leakage magnetic flux is not considered.
