摘要

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。

Integration of Novel High-Frequency Transformer With Silicon-Carbide Schottky Diodes

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.
