An electric-vehicle propulsion control apparatus includes a filter device and a power converter. The filter device is configured such that a first inductance element, a third inductance element, and a capacitor element are connected in series to constitute a series circuit, one end of the series circuit is electrically connected to low-potential-side power supply wiring connecting a rail and the power converter; the other end thereof is electrically connected to high-potential-side power supply wiring connecting an overhead line and the power converter; a second inductance element, provided between an electrical connection point of the other end of the series circuit and the overhead line, and the first inductance element are magnetically coupled; and the magnetic coupling generates mutual inductance having a positive value between the electrical connection point of the one end of the series circuit and the power converter.
