Abstract: For high frequency switch-mode power converters and supplies, planar
transformers allow good performances to be reached. They suit very well to
embedded power electronics applications, where size and weight matter. This
paper presents a modeling, simulation, and sizing tool based on a 1D analytical
model. This tool aims at helping designers describe, simulate, and know
frequency behavior of planar wound components. As soon as all measurable
impedances given as the tool outputs, device behavior becomes predictable. Due
to its analytical nature, this tool is very fast and it can be driven by
optimization software to reduce transformer losses and, finally, reduce cooling
system weight.
