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.
