WebIGBT, the current begins to increase slowly when it is turned ON and the dI/dt increases until the diode turns-off. The amount of time it takes to turn the diode OFF also increases the additional losses in the IGBT. Reﬂ ex technology, by keeping the dI/dt constant during the turn-on of the IGBT, compensates for the WebWhen the IGBT is turned off, the positive carriers injected from the p+ layer remain in the body of the device. The additional n+ layer in the punch-through configuration allows for faster evacuation of the stored positive carriers in the body. This reduces the current fall time, turn-off time and switching loss of the IGBT. portsmouth va adult education
