Abstract :
For high-frequency transformers with any number of windings, an equivalent circuit is presented that accurately predicts the effects of AC winding resistance and leakage inductance over a wide range of frequencies. This model is suitable for circuit simulation with nonsinusoidal excitation and nonlinear loads. With the addition of circuit elements to account for magnetizing inductance, core loss, and winding capacitance, the model has the potential to bring about significant improvement in the accuracy of simulation results, which could ultimately eliminate some of the costly trial and error in power converter design
