Abstract: A magnetic element includes at least one first air gap. A first portion of the first air gap is arranged between the first projection line and the second projection line. A second portion of the first air gap is beyond the region between the third projection line and the fourth projection line. Due to the air gap, the dielectric constant between the first end part of the winding and the magnetic leg and the dielectric constant between the second end part of the winding and the magnetic leg are reduced. Moreover, the electric field distribution of the first end part and the second end part will be more uniform, and the partial discharge extinction voltage will be increased. The volume and the cost of the magnetic element are both reduced. In addition, the equalizing rings are not required. Consequently, the fabricating process of the magnetic element is simplified.
