The invention provides a power converter system for a railway vehicle that is adapted both for a track circuit using the commercial power supply and a track circuit using a high-frequency alternating-current power supply without increasing the number of filter circuits and the weight of the filter circuit. In a power converter system 1 for a railway vehicle including: an LC filter circuit composed of a filter reactor 11 and a filter capacitor 12 and connected to a current collector 21 that receives a direct-current voltage; and an inverter device 13 that receives the received direct-current voltage via the LC filter circuit and converts the direct-current voltage into an alternating-current voltage for driving an alternating-current motor 22, an impedance-increasing filter circuit 14 that is composed of a resistor 141, a reactor 142 and a capacitor 143 connected in series to each other and increases the input impedance of the power converter system at a power-supply frequency of an alternating-current power supply, which is a source of the direct-current voltage, is connected in parallel with the LC filter circuit, and the resonant frequency of a resonant circuit composed of the filter circuit 14 and the LC filter circuit matches with the frequency of the alternating-current power supply.
