Study Temperature and Humidity Influence on High-Power IGBT

Abstract:

This paper has made a statistic survey on the failure rate of the appliance of high-power IGBT on the Harmonious locomotive. According to the analysis ,environmental temperature and humidity have a crucial influence on failure rate, thus a set of temperature and humidity monitoring system has been designed to investigate the environment temperature and humidity of high failure rate Four-quadrant IGBT modules, analyzing factors such as temperature and humidity and the working conditions accordingly, exploring the relationship of rising temperature of IGBT ,locomotive speed ,pressure of the air cylinder, setting a foundation for later analysis on the mechanism of troubles.
