This application note covers the following topics explaining the use of inductor coupling symbols in a capture pspice project. This transformer wont work properly because ltspice does not know this is a transformer. The Effects Of Mutual Coupling And Transformer Connection Aaronscher Com Resonant Coupling Networks Figure 6 From High Efficiency Magnetic Coupling Resonant Barrere exality corporation a transformer with individual winding inductances l1 and l2 has mutual inductance m between the windings. Transformer coupling model . In practice some flux traverses paths that take it outside the windings. Such flux is termed leakage flux and results in leakage inductance in series with the mutually coupled transformer windings. The last number is called mutual coupling coefficient and can be between 0 and 1. However if you are only interested in a
