**5. Conclusions**

In this paper, a novel current-source inverter was proposed. Through the principle analysis and experimental research, the following conclusions were drawn. (1) The high-frequency variation of the common-mode voltage of the conventional current-source inverter cannot effectively suppress the leakage current. (2) The topology proposed in this paper can effectively eliminate the high-frequency common-mode voltage of the system, thus effectively suppressing the system leakage current and satisfying the VDE-0126-1-1 standard.
