Here we’ll show how Spice can be used to provide proximity loss results for magnetics windings. Proximity loss equations are solved for a set of frequencies, and a simulation circuit is generated which predicts the proper AC losses regardless of the current waveform. Inductor winding AC resistance calcul

In the last part of this series, we saw that only one of the modulator gains found in the literature can be confirmed with measurements. Furthermore, it is shown that the discrepancies in all the models are easily resolved by proper sampling of the system. Different current-mode modulator models In the
