Transformer at Villard Circuit


 RJ45 Connector

In this example we show a FEM analysis of a transformer that is coupled with a 1D Villard circuit containing diodes and capacitors. The resulting voltage is influenced by loss effects (nonlinear saturation and leakage inductance). Read full article.
