Linear non-ideal transformer winding

Description

The Primary Winding block models linear non-ideal winding of a transformer with linear winding leakage and linear core magnetization effects. Although magnetization effects occur in the magnetic core, it is common practice to place mathematically equivalent electrical components on the electrical winding and parameterize them using electrical parameters. The figure shows the equivalent circuit diagram for the primary winding.

  • Rl is the leakage resistance.

  • Ll is the leakage inductance.

  • Rm is the magnetization resistance.

  • Lm is the magnetization inductance.
