In high power converter design, IGBT modules are often operated in parallel to reach high output currents. Evaluating the electrical and thermal behaviour of the paralleling IGBTs is crucial for the design and reliable operation of converter systems. This paper investigates the static and dynamic characterization of paralleling IGBTs and the influence of the electrical parameters on the IGBT behaviour...
Power circuit design has a strong impact on switching characteristics of power semiconductors and current sharing of paralleled devices. Optimum circuit design, which means minimum parasitic inductance, allows improving power semiconductors towards lower losses. For paralleled devices it ensures symmetric losses and minimum deterioration of drive signals. Effective rules for circuit design lead to...
Parasitic inductances are a major problem with power modules, in particular in fast switching applications. The parasitic inductance of the component interconnections causes an overvoltage condition and increases the switchoff losses in the semiconductor. Many initiatives have been investigated to reduce the parasitic inductance in power modules utilizing a complex mechanical construction of overlapping...
