WebUsing KVL and assuming zero loss in MOSFET Q1, we arrive at the following expression: i V IN L 1 t I L1,valley (eq. 11) Equation (9) attains its maximum when t = DTsw thus: I L1,peak V IN L 1 DTsw I L1,valley (eq. 12) Now the peak−to−peak current can be calculated as V D L 1fsw (eq. 13) I L1,p2p I L1,peak I L1,valley Where fsw is the ... 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. how does an ira affect taxes
