The delay time is the time during which gate voltage fall forms VGE to threshold VGET. As VGE falls to VGET during tdf, the collector current falls from Ic to 0.9 Ic . At the end of tdf, the collector-emitter voltage begins to rise. The first fall time tf1 is defined as the time during which collector current fall from 90 ...

Webthe dead time (see Fig.7-5) needs to be set longer than the IGBT switching time (toff max.). For example, if R G is increased, switching time also becomes longer, so it would be necessary to lengthen dead time as well. Also, it is necessary to consider other drive conditions and the temperature characteristics. Een insulated-gate bipolar transistor (IGBT) is een transistor die veel vermogen kan schakelen. De benodigde gate stuurspanning ligt wat hoger dan bij een MOSFET, in de orde van 15 volt.
