If u
reaches the value of the threshold voltage U
of the IGBT, it starts becoming
conductive. The greater u
is, themore the IGBTwill be turned on in what is known as
parasitic turn-on of the IGBT. This turning on usually lasts only a short time,
approximately a few 10ns to 100ns, but causes higher losses in the IGBT and may
cause faults in theadjacent electronics (chapte
