Abstract

In order for full utilization of the switching devices and safe continued operation of the power converter at the same time, the junction temperature of the switching devices needs to be accurately monitored without shutting down the motor drive. This paper derives an analytical junction temperature calculation method by using Laplace transformation and thermal network theory. Based on an actual motor drive, a simulation model is established using platform for power electronic systems (PLECS). Through comparison, the derived method is proven to be able to calculate junction temperature accurately.

基于热网络理论和拉普拉斯变换的 SiC MOSFET 结温分析计算方法

为了在充分利用开关设备的同时保证功率转换器的持续安全运行，需要在不关闭电机驱动器的情况下准确监测开关设备的结温。本文利用拉普拉斯变换和热网络理论推导出一种结温分析计算方法。基于实际的电机驱动器，使用电力电子系统平台 (PLECS) 建立了仿真模型。通过比较，证明推导出的方法能够准确计算结温。

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.
