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 a semi-conductive part is disposed between the second winding and the magnetic core. The present disclosure can effectively lower the risk of partial discharge between the second winding and the magnetic core, and thus the transformer of the present disclosure has high reliability.
