A Study of 200kVA IGBT SIV development and production for electric coache

전기철도용 200kVA IGBT SIV 개발 및 제작에 관한 연구

The SIV(Static InVerter) of the electric coach mainly consists of GTO type inverter. But, it is the drawback that GTO type inverter must have the complicated driving circuits. Recently, appearing the IGBT of high speed switching frequency, simple driving circuits, relative large capacity, GTO type inverter is changed IGBT type inverter. In this paper, IGBT type SIV substituting for the existing GTO type SIV is designed and producted. The experimental results are presented to verify the performance of the designed IGBT type SIV.
