Enhanced cross-coupled-secondaries model for multiwinding transformers

The cross coupled secondaries model, which models the leakage inductances and resistances between windings of multiwinding transformers, is enhanced to account for magnetic energy stored and power lost in the core and electric energy stored in the winding space. This is accomplished by adding inductive, resistive and capacitive elements to each winding circuit, greatly extending the frequency range for accurate modeling of high frequency transformers
