In an igbt during the turn-on time
WebIn this condition, when IGBT1 get turned on from off-state, FWD on its opposite arm, that is, reverse recovery of FWD2 is occurred. At same time, voltage of IGBT2 and FWD2 with off-state is raised. This causes the dV/dt according to switching time of IGBT1. Because IGBT1 and 2 have the mirror capacitance C GC WebWhen the power is controlled by an IGBT, the switching behaviour can be softened at both turn-on and turn-off so that the inductor is no longer required. The switching losses …

The corresponding test circuit is depicted in all of our discrete IGBT data sheets (e.g. IKQ75N120CH3, p. 14, fig. E): The picture below shows the principle current and voltage waveforms of the low side (LS) IGBT "DUT (IGBT)" during the double pulse test.
WebMar 5, 2024 · There are three types of open-circuit faults: an upper bridge arm IGBT fault (type I fault), a lower bridge arm IGBT fault (type II fault), and two IGBT faults that occur at the same time (type III fault). It is only in mode 2 and mode 3 that the operating state is affected by an IGBT open-circuit fault and that it changes the current flow.
