WebFeb 21, 2024 · From the early beginning of IGBT development in the 1980s up to now, IGBTs found their way continuously into novel application areas (e.g. [1-3]). There are two main reasons for this: firstly, the constant decrease of static and switching power losses, and, secondly, the excellent ruggedness of IGBTs regarding overcurrent or short-circuit failures. WebWhen an IGBT is turned off, it exhibits a "tail current" because holes are left in the drift region.
