In this paper, we propose the LCR filter design method and the carrier frequency decision method in the series voltage compensator. In this proposed design method, the filter $L_f$ is calculated from the peak value of the ripple current, and the filter $C_f$ is calculated from the ripple voltage component. The damping resistance is calculated from the percentage of the elimination of the carrier frequency component and the settling time. We verify a model equipment in the experiment, and the experimental results agree well with the calculated design values.
