  • Patent number: 11476713
    Abstract: A wireless power transmission apparatus including a power transmission coil that transmits electric power; a power transmission-side resonant capacitor that is connected to the power transmission coil and that, with the power transmission coil, forms a power transmission-side resonance circuit; and a self-oscillation circuit that converts a DC voltage to an AC voltage, and that supplies the AC voltage to the power transmission coil. The wireless power transmission apparatus has a state, during power transmission, in which multiple resonance points exist in a combined resonance circuit formed by magnetic coupling of the power transmission-side resonance circuit with a power reception-side resonance circuit formed from a power reception coil and a power reception-side resonant capacitor. In the state, the self-oscillation circuit operates at the lowest frequency among the multiple resonance points.

  • Patent number: 11469616
    Abstract: In a wireless power transfer arrangement (1) power is wirelessly transferred from a primary side (2) to a secondary side (3) across an airgap (8) by means of a primary resonator (6) that generates a magnetic field (9) and a secondary resonator (10) that receives the power by picking up the magnetic field (9). The secondary side (3) includes an output stage (11) that receives the AC power provided by the secondary resonator (10) and generates a DC output (13) to be provided to a load. A current sensing arrangement (18) senses the AC current flowing from the secondary resonator (10) to the output stage (11) and provides a current sense signal (16) to a power transfer controller (15) that controls the power transfer of the wireless power transfer arrangement (1) based on the current sense signal (16).
