  • Patent number: 10573455
    Abstract: Novel and advantageous insulator discs with embedded resonator coils are provided. By linking the insulator discs in a series using an appropriate mechanical mechanism, the insulator discs form an insulator or insulator string for a high power transmission line system. The resonator coils embedded inside the insulator discs therefore form a series of relay resonators that can be used for wireless power transfer through the principle of near-field magnetic coupling and resonance. The insulator string can provide the simultaneous functions of voltage insulation and wireless power transfer over the length of the string. Applications include, but not limited to, wireless power transfer in a high-voltage environment such as that encountered in high-voltage power transmission line systems.

  • Patent number: 10541558
    Abstract: Wireless power transmission (WPT) systems are provided. According to an embodiment, the WPT system uses one or more power transmitting coils and a receiver for electromagnetically coupled wireless power transfer. The electrodynamic receiver can be in the form of an electrodynamic transducer where a magnet is allowed to oscillate near a receiving coil to induce a voltage in the receiving coil, a piezoelectric transducer where the magnet causes a vibrating structure with a piezoelectric layer to move, an electrostatic transducer where movement of the magnet causes a capacitor plate to move, or a combination thereof. An alternating magnetic field from the transmitting coil(s) excites the magnet in the receiver into mechanical resonance. The vibrating magnet then functions similar to an energy harvester to induce voltage/current on an internal coil, piezoelectric material, or variable capacitor.
