Abstract: A wind power converter structure and a wind power generation system including the converter structure are provided. The converter structure includes a plurality of generator-side converters arranged in a nacelle located on a top part of the tower; a plurality of grid-side converters arranged on a bottom part of the tower or outside the tower, wherein a DC input side of the grid-side converter is coupled to a DC output side of the generator-side converter; at least one DC bus connected between the generator-side converter and the grid-side converter; and an isolation transformer of which a primary side is coupled to the AC output side of the grid-side converter, wherein a secondary side of the isolation transformer is coupled to a power grid.
