The proposed method adopts a low-pass filter to prevent ringing. Generally, reactive current cannot be detected using a DC filter; however the proposed method permits detection via voltage injection. High responsiveness and a simple construction have been achieved using the method. Simulation results indicate that active and reactive currents can be reconstructed using a single shunt current; the experimental results indicate that the proposed method can be applied to a motor drive without lowering the performance, unlike when using a current sensor.本誌: IEEJ Journal of Industry Applications Vol.12 No.4 （2023） Special Issue on “IPEC-Himeji 2022”本誌掲載ページ: 676-681 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/12/4/12_22007800/_article/-char/ja/
