COMPACT MULTIPLE TRANSFORMERS

摘要

A compact multiple transformer is provided to implement a compact layout by arranging a first transformer and a second transformer adjacently. A first transformer(101) includes a first primary winding(111) and a first secondary winding(112). The first primary winding is inductively coupled with the first secondary winding. The first transformer has a first rotation current flow direction in the first primary winding. A second transformer(102) includes a second primary winding(113) and a second secondary winding(114). The second primary winding is inductively coupled with the second secondary winding. The second transformer has a second rotation current flow direction opposite to the first rotation current flow direction in the second primary winding. The first region of the first primary winding is arranged adjacently to the second region of the second primary winding. The first region and the second region have the substantially same first linear current flow direction.
