Traction inverters and inverters for auxiliary power units in battery-powered railway vehicles, have a switching frequency of 1-5kHz owing to a high-power range. The sampling frequency of the microcontroller is selected based on its switching frequency. As the sampling frequency of a microcontroller is considered feasible if it is several tens of times the switching frequency, this paper proposes a feasible power control method with a low sampling frequency. The proposed control method is a feedback control of the average DC power per operating cycle, which eliminates the influence of single-phase power fluctuations. The controller gain is designed using a Bode diagram. 100-W-class experiments verified its inductance independence and high responsiveness, and full-scale 300-kW-class simulations demonstrated the effectiveness of the proposed power control.本誌: IEEJ Journal of Industry Applications Vol.12 No.6 （2023）本誌掲載ページ: 1078-1087 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/12/6/12_23001645/_article/-char/ja/
