Thermal Modeling of Coil Parts
Details
High-frequency inductors are one of the most significant loss contributors in a switch mode power supply (SMPSX However, in making a thermal flow simulation model, it is not realistic to model the detailed structure of a high-frequency inductor due to the high calculation cost. Therefore, to find a compact modeling method for an inductor component in SMPS, we investigated the effect of proximity losses that occurs near the air gap, and the effect of anisotropie effective thermal conductivity in an inductor winding on the winding surface temperature.
