WebFormula as, Hysteresis loss, (Ph)= [ (ηh)* (B max1.6 )* (F)* (V)] (Unit- Watt) Where, (ηh)- Constant of hysteresis loss. 4. Calculation of Total Core or Iron Loss: Total core/iron loss is the combination of the eddy current loss (Pe) and hysteresis loss (Ph) in transformer. Total Core Loss, (Pi)= (Pe + Ph) (Unit- Watt)

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.
