Abstract: A magnetic element includes a first magnetic core, a coil and a second magnetic core. The first magnetic core is made of a ferrite material, and a magnetic permeability of the first magnetic core is higher than 700. The coil is installed on the first magnetic core. The second magnetic core is formed by molding an alloy composition. In addition, the coil and at least a portion of the first magnetic core are covered by the second magnetic core.

Abstract: A transformer includes a magnetic core assembly, a bobbin, two first windings, a second winding and at least one circuit board. The bobbin includes a bobbin main body, a bobbin channel and a winding portion. The winding portion is formed on an outer periphery surface of the bobbin main body. The two first windings are disposed around the winding portion. One of the two first windings is disposed between the other one of the two first windings and the outer periphery surface of the bobbin main body. The second winding is disposed around the winding portion and disposed between the two first windings. The at least one circuit board includes a circuit board hole. The circuit board hole and the bobbin channel are communicated with each other. The magnetic core assembly partially penetrates through the circuit board hole and the bobbin channel.

Abstract: A transformer includes a magnetic core assembly, a bobbin, two first windings, a second winding and a second circuit board. A bobbin channel runs through two opposite sides of the bobbin main body. The winding portion is formed on an outer periphery surface of the bobbin main body. The two first windings are disposed around the winding portion. One of the two first windings is disposed between the other one of the two first windings and the outer periphery surface of the bobbin main body. The second winding is disposed around the winding portion and disposed between the two first windings. The second circuit board hole and the bobbin channel are in communication with each other. The magnetic core assembly partially penetrates through the bobbin channel and the second circuit board hole. The second winding and the second circuit board are connected with each other in parallel.

Abstract: A transformer includes a bobbin having a winding base and a first extending portion, a honeycomb winding wound on the winding base, a first spiral winding coil disposed on the first extending portion, a first lateral plate disposed between the first spiral winding coil and the bobbin, and a magnetic core assembly including two magnetic cores. The first lateral plate has a first ring-shaped protruding portion sleeved on the first extending portion. A channel is defined by the first ring-shaped protruding portion and the first extending portion. Each magnetic core has a first lateral post and a second lateral post. The first lateral posts are disposed opposite to each other. The second lateral posts are disposed opposite to each other. Each of the first lateral posts is penetrated through the channel. By the air insulation and isolation, the heat dissipation and safety are enhanced, and the automatic manufacture is implemented.
