A converter device is provided with: a converter circuit unit 11 for converting an AC voltage to a DC voltage, said AC voltage being supplied from two systems, that is, a Y-connection and a delta-connection of a 12-phase rectifier transformer 2; a current detection unit 12 for detecting the current flowing through a DC bus line connected to the converter circuit unit 11; an open-phase detection unit 13 connected to the delta-connection side or the Y-connection side and detecting whether or not an open-phase occurs in the connected connection; and an output unit 15 for, when it is detected from a detection signal detected by the open-phase detection unit 13 and the value of the current flowing through the DC bus line and detected by the current detection unit 12 that an open-phase occurs in the delta-connection or the Y-connection, outputting the information indicating that the open-phase occurs in the delta-connection or the Y-connection. When an open-phase has occurred, it is possible to output whether the o
