Development of auxiliary power supply simulator for electric rolling stock

This paper describes the development of the auxiliary power supply simulator for electric rolling stock. Auxiliary power supplies are required for operating air conditioning units, ventilation fans, lighting and battery charging. 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 IGBT voltage source inverter. Auxiliary power supply simulator can be used educatory purpose to teach efficiently about operating principles of SIV
