| Abstract |
This paper presents a family of prototypes of DC-DC converters, based on the zero-voltage-switching multiresonant converter (ZVS-MRC) topologies developed by F.C.Lee. These 150 W converters, operating in the MHz range, are designed to work on a common DC bus (385V) fed by a power factor controller. Four different output voltages (5 to 48V) are available. The aim of this study is to evaluate the complexity level of the implementation of such converters. Special attention is given to the magnetic components, mainly the resonant inductor, with the perspective to use, as far as possible, technological solutions which are currently applied in the 100-200 KHz range. The paper shows the different options which have been evaluated, with practical results. |
