Zusammenfassung:	To provide a noise filter capable of attenuating a transition component from a common mode component into a differential mode component, and to provide a power conversion device comprising the noise filter.SOLUTION: In a power conversion device, a noise filter 18B has: a common mode choke coil Lc, a plurality of input capacitors Cx1-1 to CX1-3 star-connected to an input side of the common mode choke coil; a plurality of output capacitors CX2-1 to CX2-3 star-connected to an output side of the common mode choke coil; and a ground capacitor CY connected between a neutral point of the plurality of output capacitors and the ground. The power conversion device has the noise filter, and an inverter connected with the noise filter.SELECTED DRAWING: Figure 3 【課題】コモンモード成分からディファレンシャルモード成分への転化成分を減衰可能なノイズフィルタ及び当該ノイズフィルタを備える電力変換装置を提供する。【解決手段】電力変換装置において、ノイズフィルタ１８Ｂは、コモンモードチョークコイルＬｃと、コモンモードチョークコイルの入力側にスター結線される複数の入力コンデンサとＣｘ１−１〜ＣＸ１−３と、コモンモードチョークコイルの出力側にスター結線される複数の出力コンデンサＣＸ２−１〜ＣＸ２−２と、複数の出力コンデンサの中性点とグランドとの間に接続される接地コンデンサＣＹと、を備える。当該ノイズフィルタと、前記ノイズフィルタに接続されるインバータと備える。【選択図】図３
