要約(英語): This paper proposes a method to detect the DC voltage in order to restore the three-phase voltage of a current source inverter (CSI). The proposed method obtains the three-phase voltage by using the DC voltage and the switching pattern of the CSI. This study improves the restore waveform by considering the delay of the filter. The proposed method can reduce the distortion at the output voltage crosses. This paper shows the characteristics of the proposed method with the conditions of the CSI, such as the modulation ratio, switching frequency, output frequency, and filter capacitance. The experimental results confirm that the proposed method effectively obtains the three-phase voltage. Furthermore, it clarifies the operation condition to obtain a good restoration waveform through the analysis results.
