Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power converter in which an electric motor accommodates and utilizes regenerated power.SOLUTION: A power converter 1 comprises plural power conversion units 14-1, 14-2 which are respectively connected to different feeding wires 2, a direct current accommodation unit 17 wich is connected to respective power conversion units 14-1, 14-2 and also connected to a secondary battery 16, and a power control unit 11. The power control unit 11 sends commands to the regeneration side power conversion unit 14 which is connected to the regeneration side feeding wire 2 and to the consumption side power conversion unit 14 which is connected to the consumption side feeding wire 2 so as to output electric power from the regeneration side feeding wire 2 to the consumption side feeding wire 2 via the direct current accommodation unit 17, and determines a voltage at the direct current accommodation unit 17 in such a manner that energy according to the sum of the regeneration power and the consumption power is inputted to and outputted from the secondary battery 16.
