Modeling pulse transformer
This document summarizes the device modeling of a pulse transformer in three sentences: 1) It uses a frequency characteristic model that can model frequencies from 100Hz to 100MHz. 2) It provides the equivalent circuit diagram and models the leakage inductance, inductance between terminals, and inductance at 1kHz transient analysis. 3) All content is copyrighted by Bee Technologies Inc.
