Influence of Auxiliary Gate and Emitter Connections on Short Circuit Behaviour of Multichip IGBT Modules
This paper investigates the influence of the auxiliary emitter and the gate connections on short circuit current behaviour of multichip IGBT power module. It reveals that the position of the auxiliary emitter connection has significant impact on the short circuit current of the power module. Experimental results validate the analysis of the short circuit current. The conclusion of this paper helps DBC layout design in terms of short circuit performance.
Impact of I2t Capability of RC-IGBT and Leadframe Combined Structure in xEV Active Short Circuit Survival
This presentation describes the new investigate results of s I2t capability for automotive IGBT power module used for xEV powertrain application. Experimental done with combination matrix of :(RC-IGBT or the conventional FWD ) x (leadframe interconnection or bondwires), These results gives giant impact on vehicle safety in terms of much higher capability in active short-circuit failure mode, in which the inverter must open all-low side switches to protect batteries from abnormally high motor surge.
New Developed 3.3kV/1500A IGBT Module
One set of new internal design and assembly process have been utilised into high power IGBT module with 140mmX190mm footprint. There are several key improvements for the module: (a) 3D busbar-substrate assembly has shown 40% less inductance than the traditional 2D structural busbars; (b) 12.5% reduction of IGBT?s thermal resistance and 25% reduction of FRD?s thermal resistance, (c) FRD performance has been enhanced, (d) ohmic losses from both metal busbars and metal layer of substrates are much lower for the new design.
Newly Developed 7th Generation 1,700V IGBT Module Product Family for Industrial Application
This paper describes newly developed 7th Generation 1,700V IGBT module. The 7th Generation 1,700V IGBT modules have been developed based on concepts of higher power density and higher reliability. To realize the concepts, many advanced technologies are applied such as power dissipation improvement by newly developed 7th generation IGBT and FWD Si dies, lower thermal resistance by high thermal conductive thinner AlN ceramics and upgrade the operation temperature up to 175deg.C.
Analytical Modelling of Dynamic Power Losses Inside Power Modules for 2-Level Inverters
Simplified power loss calculation models are commonly based on linear scaling of losses from datasheets, which reduces their accuracy, and do not allow dynamic load profile investigations in most cases, but stop at steady state considerations of losses and temperature.This paper proposes a modelling approach considering time discrete modelling of load profiles and obtaining electrical input data of chips from more accurately scaled algorithms.
Failure Protection in Power Modules with Auxiliary-Emitter Bond-Wires
In this study we show how including an auxiliary-emitter resistor in the design of the power module prevents loss of gate control after device failure, and provides a large warning signal that allows a fault control strategy to be implemented immediately and save the module from explosion.
An Efficient Active Mains Rectifier Bridge Based on Bipolar Technology
The combination of bipolar technology and an innovative driving method enables the implementation of a cost-effective active mains rectifier bridge. With the new rectifier bridge the power dissipation in the rectification stage of a power converter can be reduced by 70% and the overall system efficiency is increased by up to 1%. In power converters that operate 24/7, the active bridge pays for itself within one year.
