Control method of propulsion control device for AC railway vehicle

Railway vehicle is classified into the AC and DC railway vehicle according to the distribution of the local environment. DC railway vehicle is directly supplied to the DC power from the power line to drive the inverter but AC railway vehicle is complicated to control and drive sequence as compared to DC vehicle because of the structure for controlling the inverter and converter at the same time. In this paper we describe the sequence and method for controlling a railway driving vehicle on AC power line and confirm the analysis and control performance through computer simulation.
