    Abstract: A power conversion device according to an embodiment includes a converter unit, and an inverter unit disposed to be adjacent to the converter unit in a railroad car running direction, the inverter unit being configured to convert the DC power outputted from the converter unit to AC power. First radiation fins are attached to a surface of a first heat receiving plate opposite to a surface on which the semiconductor switching devices are attached, and second radiation fins are attached to a surface of a second heat receiving plate opposite to a surface on which the semiconductor switching devices are attached. The first radiation fins and the second radiation fins facing one another are attached to the first heat receiving plate and the second heat receiving plate so that recessed portions of the first radiation fins and recessed portions the second radiation fins are aligned with one another.

    Abstract: A power converter for an electric locomotive includes an insulating transformer, an AC/DC converter, an inverter, a PWM controller, and a voltage controller. The insulating transformer is supplied with high-voltage AC power from an AC overhead wire to convert a high voltage to a low voltage and output low-voltage AC power. The AC/DC converter receives the low-voltage AC power and performs AC/DC conversion. The inverter receives an output from the AC/DC converter and performs DC/AC conversion for supply to a load. The PWM controller outputs a PWM control signal having a predetermined pattern, the pattern for removing specific harmonic components from an output of the inverter or attenuating the specific harmonic components to at most a predetermined level. The voltage controller controls a DC output voltage of the AC/DC converter to control an output voltage of the inverter.
