High frequency, high voltage compound helical inductor coil
A compound helical inductor coil has been patented, consisting of a primary coil, a secondary coil, and a dielectric insulator all configured as helices. The primary coil and secondary coil are parallel, with the dielectric insulator separating them. The primary coil has an elongate cut-out for the outer protrusion of the insulator, while the secondary coil has a cut-out for the inner protrusion. A center conductor runs through the central axis of both coils, connecting them at each end. The coils are made of copper, and the insulator is polytetrafluoroethylene (PTFE). The turns ratio between the primary and secondary coils can be either unity or non-unity.
The patent also covers a T-coil assembly and a plasma processing system incorporating the compound helical inductor coil. The T-coil assembly includes shunt variable capacitors coupling the coils to electric ground. The plasma processing system includes an RF generator, an impedance matching network, and the T-coil assembly. The primary and secondary coils in both the T-coil assembly and the plasma processing system are made of copper, with the insulator being PTFE. The turns ratio between the coils can be either unity or non-unity, providing flexibility in the system's design and performance. Overall, the patented technology offers a novel approach to inductor coil design for various applications, particularly in plasma processing systems requiring efficient power transfer and impedance matching.
