How are transformers represented in TPC schematics?

Transformers are commonly represented in TPC schematics by two inductors with a coupling line between them. This representation effectively conveys the essential functionality of a transformer, which involves two coils of wire (the primary and secondary windings) and their magnetic coupling.

The two inductors symbolize the primary and secondary sides of the transformer, with each inductor representing one of the windings. The coupling line indicates the magnetic relationship between these two windings, which is crucial for understanding how energy is transferred from one coil to another through electromagnetic induction.

This representation not only allows for a clear understanding of the transformer’s operation in terms of its inductive characteristics but also provides insight into how voltage levels will change depending on the turns ratio of the two inductors. It emphasizes the critical aspect of magnetic coupling, which is the defining feature of transformer function.

Other representations might overly simplify the element's complexity or fail to convey the concept of magnetic coupling, which is fundamental in transformer operation.
