Abstract

This letter presents a novel and compact structure that integrates silicon-carbide (SiC) Schottky diodes within a high-frequency transformer (HFT). The proposed structure would reduce the volume of a power converter and, in turn, the system to which it is applied. It would also greatly reduce the leakage inductances of an HFT as well as the inductive electromagnetic interference to surrounding components and devices. A prototype HFT shaped much like a torus is designed for integration with SiC Schottky diodes. The three-dimensional finite-element method simulation technique is used to design and analyze the magnetic structure of the HFT including the space reserved for the SiC Schottky diodes. Experimental results are presented for both the HFT as a separate component and as a system integrated with SiC Schottky diodes.

新型高频变压器与碳化硅肖特基二极管的集成

这封信提出了一种新颖紧凑的结构，将碳化硅（SiC）肖特基二极管集成在高频变压器（HFT）中。所提出的结构将减少功率转换器的体积，进而减少其所应用的系统的体积。它还将大大降低HFT的泄漏电感以及对周围组件和设备的感应电磁干扰。设计了一个形状非常像环面的HFT原型，用于与SiC肖特基二极管集成。采用三维有限元模拟技术，设计和分析了HFT的磁结构，包括为SiC肖特基二极管预留的空间。给出了HFT作为单独部件和与SiC肖特基二极管集成的系统的实验结果。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
