A correction method for the frequency dependence of eddy current loss power of converter transformer

A correction method for the frequency dependence of eddy current loss power of converter transformer

At present, the eddy current loss of the converter transformer is estimated based on an extrapolation method recommended by the IEC-61378-2 standard and GB/T 18494.2 standard. However, practical measurements already show the recommended method has a poor accuracy for evaluating eddy current loss at...
