摘要: Considering typical conditions of railway traction applications, this paper presents an experimental and simulative analysis over-current turn-off failure in IGBT devices packaged parallel within multichip modules. Extensive is carried out by means a dedicated test-circuit. Thus, for greater insight, electro-thermal simulations at device level have been out. The results show that mismatches the properties during transient operation can lead to uneven power dissipation, significantly enhancing risk failure.
