WebGate Driver Reference Design for Parallel IGBTs With Short-Circuit Protection and Current Buffer. Design files. TIDA-00917 ... This reference design uses reinforced isolated IGBT … IGBT overcurrent and short-circuit protection are implemented using a range of methods in the experimental hardware. These are: DC bus current sensing (inverter shoot-through fault) Motor phase current sensing (motor winding faults) Gate driver desaturation detection (all faults) 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 … Meer weergeven The experimental setup utilizes a 3-phase inverter powered from the ac mains through a half wave rectifier. In this case this results in a dc bus voltage at 320 V, although the system can be also used up to dc bus … Meer weergeven IGBT protection from overcurrent conditions is a critical part of system reliability, both in terms of asset destruction and indeed safety.
