Research of IGBT failure energy transmission and energy shock
As a power switching device, IGBT has many advantages, such as high current density and low saturation voltage and it is widely used in various power engineering fields. However, IGBT is the most important failure part of power converter system. When the IGBT module is short-circuited, the short-circuit current increases sharply, causing the IGBT chip to generate heat violently. When the short-circuit energy is high enough, the chip will fail and a large amount of high-temperature and high-pressure explosive gas will be generated. After initial expansion, the explosive gas will act on the shell in the form of shock wave energy and gas. When the module shell cannot bind the failure energy, the module shell will explode. Five methods were proposed in the paper to evaluate the failure energy shock, including the shell damage assessment method, high-speed photography method, shock sensor measurement method, electrical parameter testing method, and capacitive energy release method. Through the test verification, it was found that the shell damage degree assessment method was more effective, which can make the impact of short-circuit energy on the shell become a quantitative calculation problem, so as to guide the optimization of the shell structure, evaluate the strength of the shell material, and limit the secondary damage of the failure energy to other subsystems.
