Abstract: A coil device including bobbins, a continuous first wire wound around the bobbins, and a continuous second wire wound around the bobbins. The bobbins include a first bobbin, a second bobbin, and a third bobbin. The first wire is wound around the first bobbin to form a first coil. The second wire is wound around the second bobbin to form a second coil. The first wire is wound around the third bobbin to form a third primary coil and the second wire is wound around the third bobbin to form a third secondary coil.
