| 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 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 will be discussed. |
