2.10.2 Ideal Transformer Model Parameters and Defaults
If n > 1, it is a step-down transformer; if n < 1, it is a step-up transformer.
2.11 Nonlinear Transformer
This component is based on a general model that can be customized for different applications.
It is implemented using a conceptual magnetic core and coreless coil building blocks, together
with resistors and inductors. Using this transformer, you can model physical effects such as
nonlinear magnetic saturation, primary and secondary winding losses, primary and secondary
leakage inductances, and core geometric size.
See the “Magnetic Core” description for characteristic equations of the magnetic core.
