Study and analysis of the switching characteristics of high power IGBT devices

Since IGBT devices emerges, the switching characteristics of IGBT devices were studied, in order to predict and improve the device accurate switching transient characteristics. In practical application, the switching characteristics of IGBT devices not only its physical structure, fabrication process and working principle are closely related, also and related to the working environment closely. When IGBT devices work, it is often influenced by the driving voltage and resistance and working voltage, the collector current. So the research work environment influence on IGBT switching characteristics, to optimize the performance and improve its design continuously, become the focus of the study.
