Transformer SPICE Model - FMTT

Transformer SPICE Model Edward Herbert February 14, 2008 I have been frustrated with currently available SPICE models for transformers , particularly SPICE models that included the core losses and saturation for power when applied to power converter applications. This paper presents new SPICE models that I hope are useful. The manufacturers' data for core loss parameters, both for real Transformer designs and for SPICE models, is woefully inadequate. This paper includes suggestions for more useful data as well as hints to mine more information from present data. This presentation includes an appendix "Core losses in SPICE models from core manufacturers' data". The reader may wish to look over this section before studying the SPICE models, as the relationships developed in the appendix are the basis for some of the SPICE models.

Basic ideal transformer: The SPICE model above shows a basic ideal transformer model using a behavioral current source and a behavioral voltage source.
