Typical Application Circuit s 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 result in large overcurrent levels flowing in the motor drive power circuits. Three typical … 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 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 … 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 withstand time of IGBT decreases down to 1 μs levels. Industrial motor drive … Meer weergeven The experimental setup utilizes a 3-phase inverter powered from the ac mains through a half wave rectifier.
