A power converting apparatus for electric motor vehicle propulsion is provided that is suitable for a use in which power regeneration from an inverter unit 30 to a power storing unit 50 or power supply from the power storing unit 50 to the inverter unit 30 is frequently used. The power converting apparatus for electric motor vehicle propulsion includes a converter unit 10 that receives input of a power supply voltage from the outside, converts the power supply voltage into a direct current of a predetermined value, and outputs the direct current, the inverter unit 30 that is connected to an output side of the converter unit 10 and drives an electric motor 40, and the power storing unit 50 that is connected to the output side of the converter unit 10. A converter control unit 14 included in the converter unit 10 generates a current command for the converter unit 10 and controls charging and discharge currents to and from the power storing unit 50 based on this current command.
