According to some aspects of the present disclosure, transformers having a screen layer and corresponding methods of winding transformers and are disclosed. Example transformers include at least one transformer core, at least one primary winding layer wound about the transformer core, and at least one secondary winding layer wound about the transformer core. The secondary winding layer includes a secondary winding wire having a width and a number of turns per layer. The transformer also includes at least one screen layer wound about the transformer core and disposed between the primary winding layer and the secondary winding layer. The screen layer includes a screen wire having substantially the same width as the secondary winding wire and substantially the same number of turns per layer as the secondary winding wire, to reduce common mode noise in the secondary winding layer.
