中文摘要

未来航空器对电力电子变换器的功率密度和效率要求日益提高。碳化硅(SiC)器件虽能显著降低损耗,但其高开关速度会导致换流过程中的电压过冲与EMI问题。本文研究了一种集成电容的低电感SiC功率模块,旨在优化开关性能,抑制过冲,提升变换器整体效率与电磁兼容性。

English Abstract

Future aircrafts will be composed of high number of power converters having always higher power density and efficiency. In order to increase performance of such converters, a good option is the use of silicon carbide (SiC) transistors. Although these components reduce losses when compared to their silicon-based counterpart, they increase switching speed and overshoot during commutation, which can ...
