Lorandt explains how easy it is to calculate the inductor for a DCDC buck converter and also the total losses for this inductor by using REDEXPERT. He enters all the parameters for his converter, and select a WE-MAPI, where the DC losses, AC losses, total losses and expected temperature rise is determined. Further he explains the Würth Elektronik AC loss model, which is based on measurements of the real components. The simulation is also verified in the lab.
