This paper presents a development of the auxiliary power supply simulator for a electric rolling stock. An auxiliary power supplies are required for operating air conditioning units, ventilation fans, lighting and battery charging. Traditionally this function has been fulfilled by Motor-Alternator sets. In recent years, high performance of semiconductor and micro processor, availability and price have made three phase voltage source inverters as an attractive alternative to MA Sets. From the baseline model of the SIV(Static InVerter) for electric rolling stock, we designed the scale down model of the auxiliary power supply simulator consisting of an IGBT three phase voltage source inverter. The auxiliary power supply simulator can be used educatory purpose for training efficiently about operating principles of SIV.

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.
