Integrated technology and performance for multi-kilowatt power electronic converters-an evaluation

Abstract

This paper presents an overview of the current state of the technology for electromagnetic integration of high power electronic converters. Some of the materials technologies needed for manufacture are described. As an example a completely integrated experimental multi-kilowatt resonant DC-DC power converter is discussed, together with some problems encountered and their solution. Experimental results are also given. A possible extension of the technology to hard switched, but snubbed and clamped power converters is discussed. Some of the thermal problems together with a thermal analysis are addressed. Conclusions about the technology are drawn and possible future developments investigated.<>
