Abstract
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 turn on of multiple IGBTs. This operation can cause a significant increase in stress on the IGBT and especially on the free wheeling diode. Countermeasures to cope with these problems will be discussed
