A 72 kVA very fast four-quadrant converter based on hybrid Si-SiC IGBTs

In this paper, the design and experimental results of a prototype of a 72 kVA very fast converter for physics research are presented. Hybrid Si-SiC IGBT power modules and an advanced fast control scheme were used to achieve very small response latency (<;50 μs) and high current control bandwidth (3 kHz).
