This document describes a simplified SPICE behavioral model for saturable transformers. The model focuses on modeling the hysteresis loop behavior of transformer cores within their operating area by allowing users to shape the B-H curve. Key parameters include the saturation flux density, remanent flux density, coercive field, and saturation field, which define the hysteresis loop. Examples are provided on how to model 1:1, 2:1, and 1:2 transformer configurations using the saturable core subcircuit in LTspice.
The document discusses five types of transformer models: 1) 1:1 ideal transformer, 2) 1:1 phase reverse ideal transformer, 3) 2:1 ideal transformer, 4) 1:2 ideal transformer, and 5) 1:2 center tap ideal transformer. It provides the parameter settings for each transformer type, including inductance, turns ratio, and series resistances for each winding. The parameters have default values for demonstration in the listed figures.

This document describes a simplified SPICE behavioral model for a saturable transformer. It provides an overview of the model concepts and parameters that characterize the saturable core and ideal transformer components of the model. These include BSAT, RLOSS, LM, and BEXP for the core, and N, RP, RS, and LP for the transformer. The document also provides examples of simulations using the model to demonstrate its hysteresis behavior under different excitation conditions.
