Zusammenfassung:	The invention discloses a three-level 1140V wind power double-fed converter, and solves the problems of low power generation efficiency and high power generation cost of a doubly-fed unit in the priorart. The converter comprises a transformer, a grid-connected cabinet module, a control cabinet module, a power cabinet module and a generator. The output end of the transformer is connected with theinput end of the grid-connected cabinet module; the output end of the grid-connected cabinet module is connected with the input end of the generator, the control end of the grid-connected cabinet module is connected with the input end of the power cabinet module, the power cabinet module is further connected with the control cabinet module, the output end of the generator is connected with the power cabinet module, and the rated output voltage of a generator stator of the generator is 1140V. According to the invention, the 1140V three-level electrical transmission technology is adopted, so that the output switch state
