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.

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.

Abstract: A magnetic assembly includes a magnetic core and a winding. The magnetic core comprises an upper cover, a lower cover and at least one core column provided between the upper cover and the lower cover, the core column presents a prismatic shape and has at least two lateral surfaces, the lateral surfaces intersect with each other to form at least two longitudinal ridges, and the longitudinal ridge extends along the longitudinal direction of the core column. The winding, winding around the core column, a first semi-conductive component is provided between the core column and the winding at the position corresponding to the longitudinal ridge.
