Computer aided design and modeling of high frequency magnetic components

A new computer-aided design program is presented suitable for design, optimization and modeling of high frequency multiwinding transformers and inductors in any power electronics applications (converters and inverters). Depending on the arrangement of the windings and the ambient temperature on one hand the winding losses and the core losses can be calculated if the voltage and current waveforms at the terminals are known in principle. On the other hand state space models or equivalent circuits of different accuracy can be determined and implemented easily into simulators like SABER. An optimization routine allows the interactive optimization of high frequency magnetic components regarding losses, weight or height
