High power density DC/DC-converter using coupled inductors

This paper presents a high power density coupled tape-wound inductor consisting of nano-crystalline material used in a DC/DC converter. In a first step the comparison of the 2-phase coupled inductor (CI) with the 2-phase interleaved converter (SII) is presented. Second step is designing the CI ρ/η-pareto analysis. To test the device a high power density SiC-converter is designed. The experimentally tested prototype is operating at V
_h
= 400V, i = 100A, f
_s
= 90kHz, aimed at an overall power density of ρ = 40kw/1.
