Abstract: A power conversion module is disclosed. The power conversion module includes a circuit board, an adapter board, a first component and a second component. The second surface of the circuit board includes a concave region. The circuit board has four sidewalls. The first surface of the adapter board is attached to the second surface of the circuit board. The first surface of the adapter board includes a component disposing region, and the component disposing region is corresponding to the concave region. The first component is disposed in the concave region. A height of the first component is less than or equal to a depth of the concave region. The second component is disposed in the component disposing region and accommodated in the corresponding one of the concave region. A height of the second component is less than or equal to the depth of the concave region.

Abstract: A magnetic device includes two common magnetic legs, a plurality of coupled magnetic legs, and two windings. The first winding includes a first input part, a first intermediate part and a first output part. The second winding includes a second input part, a second intermediate part and a second output part. The first input part is disposed between the first common magnetic leg and the first coupled magnetic leg. The second input part is disposed between the second common magnetic leg and the first coupled magnetic leg. The first intermediate part and the second intermediate part are disposed between every two adjacent coupled magnetic legs. The first output part is disposed between the first common magnetic leg and the last coupled magnetic leg. The second output part is disposed between the second common magnetic leg and the last coupled magnetic leg.
