摘要: Large inverter-systems are characterized by a significant number of parallel IGBTs operating on the same DC-link. The IGBT-phases cross coupled their mutual stray inductance. This paper investigates special effects occurring due to nearly simultaneous turn multiple IGBTs. operation can cause increase in stress IGBT and especially free wheeling diode. Countermeasures cope with these problems will be discussed
