Abstract: A transformer includes a magnetic core, a first winding and at least one second winding. The magnetic core has a window through which the first winding passes through without contacting the magnetic core. The second winding passes through the window of the magnetic core and is wound on the magnetic core. The second winding has a distance from the first winding, and the second winding has a first insulating part disposed on an outer surface of the second winding facing the first winding.
