摘要

近年来，SiC在牵引逆变器开关器件中的应用备受关注。通过应用SiC器件，电机能够增加再生能量，并通过缩短供电时间来降低功耗，因为与Si-IGBT逆变器相比，驱动电机的电流更大，从而提高了电机的转矩性能。本研究以1.5 kV直流轨道车辆牵引逆变器采用SiC器件为例，通过数值模拟定量研究了增加逆变器损耗与节能效果之间的权衡关系。

Analysis of Energy-Saving Effect for Applying a SiC Switching Device to Inverters for Railway Vehicles Drives

In recent years, applying SiC to switching devices of traction inverters has been attracting attention. By applying SiC devices, motors are able to increase the regenerative energy and reduce the power consumption by shortening powering time due to improved motor torque performance by driving motors with the larger current than the case of an Si-IGBT inverter. In this study, the trade-off relationships between increasing the loss of inverters and the effect of saving-energy are quantitatively studied by numerical simulations, assuming that SiC devices are applied for 1.5 kV DC railway vehicle traction inverters.

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.
