Latest Patents

One of Jie Li's latest patents is titled "Self-resonant coil with series LC resonance and electric field cancelation." This invention features a coil structure designed for near-field wireless power transfer. It integrates a traditional inductor and an external capacitor into a single coil, achieving series resonance through a terminal connection and layering method. The design includes a distributed turn-to-turn interleaving structure that cancels the electric field, reducing interference with neighboring components, such as touch screens. This innovation not only saves costs and space by eliminating the need for a separate resonant capacitor but also offers low-profile and fabrication convenience based on RGB technology. It has potential applications in both consumer electronics and electric vehicle wireless charging.

Another notable patent is the "Series self-resonant coil structure for conducting wireless power transfer." This patent discloses a series self-resonant coil structure that includes a top coil element and a bottom coil element, both configured in a spiral and planar arrangement. These elements are positioned in a stacked arrangement, with a dielectric layer element placed between them. This alignment produces series resonance in the coil structure, enhancing its efficiency for wireless power transfer.
