Abstract :
Properties and performance of different device structures for symmetric blocking IGBTs are described and compared to series connections of PT-IGBTs with Si-diodes and SiC Schottky diodes. Based on device simulations, optimized device structures for symmetric blocking NPT-IGBTs with planar and trench gate are performed. By using dielectric charge traps as new structure elements, even the good performance of Trench-IGBTs could be exceeded.
