High-performance high-frequency po er magnetic design power
Select winding configuration configuration. Approximate analytical models for winding loss, core loss,, and thermal resistance. Co-optimize magnetics design with circuit design:
Switching frequency Inductance value Magnetic component geometric parameters
Goal: efficiency vs vs. size tradeoff (thermal constraint)
Fine tune design with finite-element analysis.
