Abstract
A magnetic dev ice includes a core structure, at least one inductor winding and at least two transformer windings. The core structure includes at least one inductor column and at least two transformer columns. The at least one inductor winding respectively winds around the at least one inductor column. The at least two transformer windings, wind around the at least two transformer columns respectively, and the transformer winding includes primary winding and secondary winding. Wherein the magnetic flax directions on adjacent transformer columns are opposite to each other when providing a current in the corresponding primary windings simultaneously.
