| Abstract |
The emergence of high power IGBT modules leads to high power switched. In this condition, designer must find means of protecting these devices against explosion of the case when a
fault occurs such as a short circuit. A fuse in series with the component can prevent such an explosion. This paper will discuss on the mechanism of the explosion of an IGBT under short circuit condition. This explosion can be attributed to two phenomena : electromagnetic forces due to high current inside the device and local overpressure due to the high energy developed. Experimentation have
been performed to test the influence of those phenomena and their contribution in the explosion of the case. With this study, the ideal fuse's rating can be selected in order to protect the IGBT case. |
