Ideal linear electrical Transformer
Information
The transformer is a two port. The left port voltage v1, left port current i1, right port voltage v2 and right port current i2 are connected by the following relation:
| Vp | | Lp M | | Ip' |
| | = | | | |
| Vs | | M Ls | | Is' |Lp, Ls, and M are the primary, secondary, and coupling inductances respectively.
Parameters
| Name | Default | Description |
|---|---|---|
| Lp | 1 | Primary inductance [H] |
| Ls | 1 | Secondary inductance [H] |
| M | 1 | Coupling inductance [H] |
