- Level 0 models an ideal lossless transformer with linear magnetizing inductance.
- Level 1 models an ideal lossless transformer with piecewise linear magnetizing inductance. No leakage.
- Level 2 models an ideal transformer with piecewise linear magnetizing inductance. Includes leakage inductance referred to the first primary winding and DC winding resistance for each winding.
- Level 3 models the transformer using a full reluctance (magnetic circuit) model. MDM is required for generating and modifying a Level 3 model.
As with all multi-level models, it allows the changing of model complexity without modifying the schematic.
