The internal bootstrap driver gives great advan. R5 controls the gate current and possibly prevents damaging current from flowing back to the driving circuit if there is some source inductance. The L is an high-voltage device, manufac. The diode connected in series to the DMOS has. The updated every day, always provide the best quality and speed. V drop has to be taken into account when the volt. Sign up using Facebook. It has to be: Spehro Pefhany k 4 The bootstrap driver introduces a voltage drop.

It slows the turn-on, and the diode shunts it so the IGBT turns off quickly. At low frequency this drop can be ne. Without that, you could get shoot-through under that condition which would destroy the IGBTs- since they’re in series across the supply voltage. According to me they are used as potential divider, but can any one tell why it is needed over there?


CBOOT selection datasheeet charging: It is more likely that it is there to limit the inrush current to the insulated gate of the IGBT. Arrow Electronics Mouser Electronics.
