Abstract :
A complete coupled inductor characterization method, including leakage flux, is described, and its SPICE model is presented. Another SPICE model is developed for p-p ripple current determination in the windings of the coupled inductor in a switching converter and its use is extended to AC stability and audiosusceptibility analyses.<>
