Webis not common, and an extra method is needed to calculate the power consumption. In this article, a mathematic method is applied to estimate the power consumption. Power … WebHysteresis loss is therefore constant, regardless of changes in VIN or load cur-rent. Core eddy current loss, on the other hand, is really I2R loss in the core material. If VIN doubles, Peak I2R loss quadruples, but since D is halved, aver-age I2R loss doubles. Thus core eddy current loss is proportional to VIN. Worst case is at high VIN.
