大型逆变器系统的特点是在同一直流链路上运行大量并联 IGBT。 IGBT 相通过其互杂散电感交叉耦合。本文研究了多个 IGBT 几乎同时开关所产生的特殊效应。此操作可能会导致 IGBT 和续流二极管上的应力显着增加。讨论应对这些问题的对策
Large inverter-systems are characterized by a significant number of parallel IGBTs operating on the same dc-link. The IGBT-phases are cross coupled by their mutual stray inductance. This paper investigates the special effects occurring due to nearly simultaneous switching of multiple IGBTs. This operation can cause a significant increase in stress on the IGBT and on the free wheel diode. Countermeasures to cope with these problems are discussed
