To provide a harmonic reduction device that secures bearing force against an inrush current in a power module of an active filter circuit.SOLUTION: A power conversion device 10 is connected in parallel between an AC power source 100 and a rectifier circuit 20, and includes an active filter circuit 60 that suppresses harmonic currents. The active filter circuit 60 includes an active filter module 50 in which a plurality of switching elements for generating compensation currents for suppressing the harmonic currents and a control circuit for controlling the switching elements are built in one package. The control voltage of the active filter module 50 is 16.0 V or higher.SELECTED DRAWING: Figure 4 【課題】本開示が解決しようとする課題は、アクティブフィルタ回路のパワーモジュールにおける突入電流に対する耐力の確保である。【解決手段】電力変換装置１０は、交流電源１００と整流回路２０との間に並列接続され、高調波電流を抑制するアクティブフィルタ回路６０を備えている。アクティブフィルタ回路６０は、高調波電流を抑制するための補償電流を生成する複数のスイッチング素子およびスイッチング素子を制御する制御回路が１つのパッケージに内蔵されているアクティブフィルタモジュール５０を有している。アクティブフィルタモジュール５０の制御電圧は１６．０Ｖ以上である、【選択図】図４
