1.1.1 Transformer linearity, impedance matrix and equivalent circuit

Transformer non-linearities are mainly due to the magnetic circuit. Unlike their LF counterparts, whose magnetic circuit uses ferromagnetic materials, HF transformers use ferrites, or operate without a magnetic circuit. As a result, their behavior is virtually linear as long as the magnetic material is not too close to saturation. With very few exceptions, it can be said that during...
