Review of IGBT junction temperature acquisition method
摘要
Abstract
Life prediction and reliability analysis of IGBT modules has a close relationship with junction temperature,so the acquisition method of IGBT junction temperature is the basis to enhance the reliability of IGBT modules.In this paper,the IGBT junction temperature acquisition method is divided into simulation method and detection method.Junction temperature simulation method is setting up IGBT models firstly and then computing the junction temperature,and the detection method is measuring the junction temperature of IGBT in real time.This paper analyzes the two categories of junction temperature acquisition method,classifies all the measurement methods by their characteristics and expounds respectively,and then,describes their advantages and disadvantages,as well as the range of application.At last,this paper points out the trend of measurement and the key issues to be solved,so as to promote the further development of the field.关键词
