Igbt protection
WebAs described previously, in the event of a short-circuit, the IGBT must be protected as soon as possible. Therefore, the time from overcurrent detection to the complete turn-off in each circuit must work effectively as fast as possible. WebInsulated Gate Bipolar Transistor. S. Abedinpour Ph.D., K. Shenai Ph.D., in Power Electronics Handbook (Third Edition), 2011 Publisher Summary. The insulated gate bipolar transistor (IGBT), which was introduced in early 1980s, is becoming a successful device because of its superior characteristics. IGBT is a three-terminal power semiconductor …

IGBT protection from overcurrent conditions is a critical part of system reliability, both in terms of asset destruction and indeed safety. IGBTs are not regarded as a fail-safe component and their failure can result in a dc bus capacitor explosion and complete drive failure.5Overcurrent protection is typically … Meer weergeven Industrial motor drives can operate in a relatively harsh environment in which high temperature, ac line transients, mechanical overload, miswiring, and other contingencies can occur. Some of these events can … Meer weergeven The short-circuit withstand time of an IGBT is related to its transconductance or gain and the thermal capacity of the IGBT die. Higher gain leads to higher short-circuit current levels within the IGBT, so clearly lower gain … Meer weergeven Overcurrent and short-circuit detection and turn-off in a very short time period are becoming ever more important as the short-circuit … Meer weergeven The experimental setup utilizes a 3-phase inverter powered from the ac mains through a half wave rectifier.
