This paper presents a junction temperature controller which increases the reliability of IGBT power modules in power electronic applications without affecting the demanded output power. Power electronic applications have to deal with varying load conditions. These varying load conditions lead to temperature swings which lead to mechanical stress of common(More)
By producing chromosome substitutions with ‘Imperial rye’ chromosomes 4R (C) and 7R (D) in the wheat cultivar ‘Chinese Spring’ two spontaneous translocation lines were obtained. One involves segments of wheat chromosome 4A and rye chromosome 7R, the other involves portions of wheat chromosome 7B and rye chromosome 4R
