A composite magnetic core assembly includes an inner magnetic core and an outer magnetic core. The inner magnetic core is made of a high saturation flux density and low permeability material. The outer magnetic core is made of a low saturation flux density and high permeability material. The outer magnetic core includes a ring-shaped wall and a receptacle. The inner magnetic core is accommodated within the receptacle.

Composite magnetic core assembly, magnetic element and fabricating method thereof

A bobbin used in a transformer is disclosed. The bobbin includes a main body, two side walls, two wire collecting bases and at least one extension wire collecting base. The main body has a tunnel. The two side walls are disposed on the two ends of the main body, respectively. The tunnel passes through the two ends of the main body and the two side walls. The two wire collecting bases are disposed on the two side walls respectively or on one of the two side walls. Each wire collecting base has at least one wire collecting part. The extension wire collecting base has at least one extension wire collecting part. The extension wire collecting base can couple with the wire collecting base.

Bobbin and transformer comprising the same

Transformers are provided. A transformer comprises a ferromagnetic core unit; a bobbin coupled with the ferromagnetic core unit; at least a winding unit as a primary winding and at least a plate as a secondary winding. Also, some of the winding units can act as a secondary winding. At least a winding unit and at least a plate are alternatively stacked in a staggered manner. A conductive wire is wound around the winding unit.
