ABSTRACT:
A transformer includes a first electrical conductor, a second electrical conductor and a core. The second electrical conductor is electromagnetically coupled with the first electrical conductor. The second electrical conductor includes at least one multilayer spiral coil, which is formed by winding a conductive wire and has a through hole at its central portion. Both ends of the conductive wire extend outward from a periphery of the multilayer spiral coil. The core penetrates through the through hole and covers at least one portion of the first electrical conductor and the second electrical conductor.
