Abstract
Abstract It is pointed out that some mistakes in research article (Chang, Liang, et al., 2018). There were existing mistakes in the conception, theoretical analysis method and conclusion of loss separation. I have shown that authors to obtained conflict between the experimental data and theoretical analysis conclusion. There were existing serious mistakes in the experimental data measurement in the article. Loss per cycle versus frequency curves for effective permeability μe = 60 of Fe-Si powder core are plotted as a correction. The rate of hysteresis loss power in power loss (Ph/Pt) at different magnetic flux densities and frequencies for effective permeability μe = 60 of Fe-Si powder core is demonstrated.
