To aim for downsizing a whole device mounted on a railway vehicle while restraining a noise component of a return wire current.SOLUTION: An active filter device is provided that comprises a pantagraph 002 for collecting a voltage from an overhead power line 001, a first lowpass filter configured by connecting an inductor 003 for restricting AC component of an output voltage of the pantagraph and a first capacitor 005, a first invertor 006 for converting an output voltage of the first lowpass filter into AC and an induction motor 007 controlled by the first invertor. The active filter device is mounted on a railway vehicle driven by the induction motor. This device comprises a voltage detector 008 for detecting voltage between terminals of the first capacitor, an active filter controller 009 for generating a control signal using the output signal of the voltage detector, a second inverter 010 performing an inverter operation based on the control signal, and a second capacitor 004 connected to an output terminal of the second inverter and a high potential terminal of the first capacitor.SELECTED DRAWING: Figure 2

    【課題】帰線電流のノイズ成分を抑圧しつつ鉄道車両に搭載する装置全体の小型化を図る。【解決手段】架線001から電圧を集電するパンタグラフ002と,パンタグラフの出力電圧の交流成分を抑圧するインダクタ003と第1のキャパシタ005を接続して構成した第1のローパスフィルタと,第1のローパスフィルタの出力電圧を交流に変換する第1のインバータ006と,第1のインバータにより制御される誘導電動機007とを備え,誘導電動機により駆動される鉄道車両に搭載する,アクティブフィルタ装置である。この装置は、第1のキャパシタの端子間電圧を検出する電圧検出器008と,電圧検出器の出力信号を用いて制御信号を生成するアクティブフィルタ制御部009と,制御信号に基づきインバータ動作する第2のインバータ010と,第2のインバータの出力端子と第1のキャパシタの高電位端子に接続された第2のキャパシタ004を備える。【選択図】図2
