Abstract :
Three design methods, widely used for high frequency inductors and transformers, are critically compared using, as a basis, the example of low profile, small footprint, low loss 500 kHz devices. In comparison to the results obtained from more detailed finite element models, it is shown that the standard methods provide surprisingly good estimates of the copper and core losses
