Full-wave rectifier with center-tapped transformer is a popular and competitive topology for power supply with high power density. Main transformer and output inductor are two large size components and have great roles on the power supply's form factor. From the view of volume and height in a real product, a new integrated magnetic structure is proposed in this paper. The proposed structure has four...
In order to overcome the disadvantages in traditional “EE” shape coupled inductors that the distributions of the air gaps are too concentrated, the distributions of the magnetic pressure and flux are not uniform, the air gaps are too nearly to the windings, this paper proposes a new structure of coupled inductors. It is proved with simulation and experiment that in the new structure, a parallel connection...
The aim of the paper is to compare the design of direct-drive permanent-magnet (PM) generators associated with horizontal axis tidal turbines. The turbine/generator couplings are examined. These turbine/generator couplings consist of a POD and Rim-driven assembly. In a Rim-Driven association the electrical generator active parts are inserted in a duct surrounding the blades. For POD generator insertion,...
The stirling convertor is a high efficient power generator, many kinds of heat source can be used in this technology with good suitability, high efficiency, simple structure and long life. As the important component of the stirling convertor, linear generator can adapt well with the stirling engine. The structure of the generator is cylinder type of moving permanent magnet, which is single-phase and...
The trend in Intermediate Bus Converter (IBC) is increasing output power demands and higher operating frequencies, while the appearance of GaN devices will improve the power density of the converter possibly. This paper analyzed the high frequency characteristics of GaN devices and its advantages at high frequency applications. Owing to difficulties in designing driver circuit and layout, the paper...
