PROBLEM TO BE SOLVED: To make it possible to supply DC voltage to a traction system from various kinds of AC or DC voltage by using a common converter. ;SOLUTION: A first power supply element 8A and second power supply element 8B connected to a power line 9 supply power to the power supply device for a traction system C. The first power supply element 8A is connected to the primary windings 6 of a power transformer 5 with a first connecting element 11A. A second connecting element 11B connects the second power supply element 8B to either the power terminal 7 of the traction system C or the midpoint 10 of series converters 1, 2.;COPYRIGHT: (C)1998,JPO
