A Distributed-Parameter Approach to the High-Frequency Network Representation of Wide-Band Transformers.

An approach to the high-frequency representation is developed from the point of view of distributed-parameter networks. This viewpoint may be directly employed to compute insertion or transmission functions. Alternatively, it provides a method for determining the element values for lumped-parameter equivalent circuits. This method is most easily applied to transformers having two winding layers with turns ratios which are either very nearly unity or which depart very greatly from unity, and the paper largely confines itself to these cases. Distributed-parameter insertion-voltage ratios for a number of common two-winding transformer connections are presented and compared with experimental results.
