How does the IGBT module conduct? The structure of IGBT silicon wafers is very similar to the power MOSFET. The main difference is that IGBT adds the P-prolapse and the N buffer layer (NPT-non-pass-IGBT technology does not increase this part). A MOSFET drives two bipolar devices. J1 knots are used between the P and N r……
