A transformer apparatus provides a primary winding and a secondary winding. The primary winding is divided into multiple primary winding layers. Each primary winding layer includes a number of primary layer turns. The secondary winding includes several secondary winding layers. In some embodiments, the transformer includes alternating primary and secondary winding layers wound around a bobbin structure. At least one secondary winding layer is positioned adjacent a primary winding layer. In some embodiments, the number of primary layer turns in each primary winding layer is equal to the total number of primary winding turns divided by the number of primary winding layers. A method of winding a transformer is also provided.
