Abstract: An adjustable leakage inductance transformer includes a magnetic core, a primary side coil and a secondary side coil. The magnetic core includes a magnetic core column structure, which has a central column, a first outer column and a second outer column. The primary side coil is wound on the first outer column and the second outer column by a first primary side coil loop number and a second primary side coil loop number, respectively. The secondary side coil is wound on the first outer column and the second outer column by a first secondary side coil loop number and a second secondary side coil loop number, respectively, the first primary side coil loop number is not equal to the first secondary side coil loop number, and the second primary side coil loop number is not equal to the second secondary side coil loop number.

Abstract: A transformer includes a magnetic core, a primary side winding and a plurality of secondary side windings. The magnetic core includes a first outer column, a second outer column, an upper cover and a lower cover. The first outer column and the second outer column are disposed between the upper cover and the lower cover. The primary side winding is disposed on the first outer column and the second outer column, and the plurality of secondary side windings are disposed on the first outer column and the second outer column. Each of the secondary windings has one end passing through a region between the first outer column and the second outer column.
