Computer aided high frequency transformer design using an optimized methodology

A new methodology for designing transformers has previously been developed. This model takes account of switching type waveforms encountered in switching mode power supplies, inclusive of high frequency skin and proximity effects. The selection of the transformer core has been optimized to minimize the core and winding losses. This paper will demonstrate a computer aided design package written for Windows to implement the optimized methodology for the first time. The package also incorporates formulas to find the optimum foil or layer thickness in a multilayer winding. These formulas apply to any arbitrary periodic current waveform. An overview of the adaptation of the underlying theory for use in computer aided design will be presented, along with a number of screenshots of the software in action.
