FILTER DEVICE AND ELECTRIC ROLLING STOCK DRIVE CONTROLLER

A filter device 5 that removes a noise current generated by an inverter 6 includes a first filter capacitor 52a that is provided in parallel to a direct-current unit of the inverter 6, a first filter reactor 51a that is provided between a high-potential side of the first filter capacitor 52a and an overhead line 1 that is a power supply source of direct-current power, and a series circuit unit 56 in which a fuse 53 serving as a circuit disconnecting unit that is disconnected when a current larger than a rated current flows therein, a second filter reactor 51b serving as an inductance element, and a second filter capacitor 52b serving as a capacitance element are connected in series, where one end of the series circuit unit 56 is connected to a low-potential side of the first filter capacitor 52a and one end of the first filter reactor 51a is connected to the series circuit unit 56.
