The present invention discloses a converter provided with high-temperature superconduction direct-current bus-bars and used for a wind power generator. The converter includes a rectifier, an inverter and superconduction cables; the alternating-current end of the rectifier is connected with the output end of the wind power generator; the direct-current end of the rectifier is connected with the direct-current end of the inverter through the superconduction cables; the superconduction cables are used as direct-current bus-bars to realize energy transmission; the alternating-current end of the inverter is connected with a transformer; electric energy is outputted through the transformer; and the converter can be of a multi-rectifier structure or a multi-inverter structure or a multi-rectifier and multi-inverter-combined structure. According to the converter of the invention, the high-temperature superconduction cables are adopted as the direct-current bus-bars, and therefore, low-loss long-distance energy transmission is realized. The converter is applicable to large-scale wind power generator sets.
