High insulation Power supply for high-power IGBT gate drivers in a multilevel converter

Résumé

Actually in ALSTOM’s locomotives, the power train is supplied by a heavy 25kV/3kV transformer. To reduce the weigh and volume of the system, a multilevel converter directly linked to the catenary, is intended to be developed. So, each component of the power electronic system has to be insulated for the maximal voltage (60kV). To respond to this constraint, for driving power supply of converters, the “Double Galvanic Insulation Transformer” (DGIT) was developed.
