Title
(JA) フィルタ装置および電気車駆動制御装置
Abstract
(JA)

インバータ6が発生するノイズ電流を除去するフィルタ装置5は、インバータ6の直流部と並列に設けられた第1のフィルタコンデンサ52aと、第1のフィルタコンデンサ52aの高電位側と直流電力の電力供給源である架線1との間に設けられた第1のフィルタリアクトル51aと、電流定格より大きい電流が流れると切になる回路切断部としてのヒューズ53、インダクタンス要素である第2のフィルタリアクトル51bおよびキャパシタンス要素である第2のフィルタコンデンサ52bとを直列に接続した直列回路部であって、その一端が第1のフィルタコンデンサ52aの低電位側に接続され、第1のフィルタリアクトル51aの一端が接続される直列回路部56と、を備える。
