Some limits of integrated L-C-T modules for resonant converters at 1 MHz

Integrated inductor-capacitor-transformer L-C-T technology has been the subject of research over the last few years. Research into producing optimum design equations has been conducted. To determine some of the physical and technological limitations of the integrated L-C-T technology, a 1-kW 1-MHz resonant DC-DC power converter was designed and built. The design was limited only by in-house material, construction and technological restrictions. Through this process, it is hoped that some of the current technological limitations can be quantified. The design and construction process is given, while some of the limits of this technology are derived from experimental results.
