Abstract

Railways in many countries are supplied by 3 kV DC voltage. An electrical insulation between the high voltage and the consumer side at the basis of a medium frequency transformer using 6.5 kV IGBT modules is a recurring theme of a number publications. An auxiliary power converter (APC) for locomotives with output power of 100 kW surviving external actions and interior faults, having improved energy characteristics is proposed in this paper. A theoretical analysis has been endorsed by modeling and experiments.
