WebMar 18, 2024 · Hi TechGirl, the switching losses of an IGBT are measured using so-called double-pulse tests. 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.
