Patent ID: 8203412

Claim:
A double active parts structure of a reactor comprising a reactor active part, wherein: the reactor active part comprises two separate active parts, which are coupled together through inner coils, the coils in the two active parts can be coupled together in series or in parallel; and the manner of coupling the coils in the two active parts together in series can be that one end of the coil in the first active part, i.e., the first coil, is a leading-in end, the other end of the first coil is connected to one end of the coil in the second active part, i.e., the second coil, and the other end of the second coil is a leading-out end, so that a serial connection is formed; the serial connection also can be that the first coil is connected to the second coil in series by using leading-in wires in the middle of the coils, i.e., the first coil employs a leading-in wire in the middle of the first coil and leading-out wires in both ends of the first coil, and the leading-out wires of the first coil are connected in parallel to be a leading-in wire of the second coil, the second coil employs the leading-in wire in the middle of the second coil and leading-out wires in both ends of the second coil, the leading-out wires in both ends of the second coil are connected in parallel, and the parallel connection between the leading-out wires in both ends of the first coil is connected to the leading-in wire of the second coil in series.
