  "textContent": "The present application discloses a filter circuit of a direct-current power supply, a filter, an electric drive controller, and an automobile. The filter circuit of the direct-current power supply comprises a positive direct-current bus, a negative direct-current bus, a charging cable, and a filter circuit having at least three stages. The positive direct-current bus comprises a positive direct-current bus input end and a positive direct-current bus output end. The negative direct-current bus comprises a negative direct-current bus input end and a negative direct-current bus output end. The charging cable comprises a charging cable input end and a charging cable output end. The filter circuit is separately connected between the positive direct-current bus input end and the direct-current bus output end, between the negative direct-current bus input end and the negative direct-current bus output end, and between the charging cable input end and the charging cable output end.",
