Abstract
Official abstract text for this publication.
A wireless energy transmission system includes a wireless energy transmitting device and a wireless energy receiving device configured to receive power from the wireless energy transmitting device through a magnetic field. The wireless energy transmitting device includes a signal generator configured to include a resonator including at least one inductor and at least one capacitor and to generate at least two signals having a 90-degree phase difference from each other. The wireless energy receiving device includes a frequency adjustor configured to match a frequency between the wireless energy transmitting device and the wireless energy receiving device.
First claim
Opening claim text (preview).
What is claimed is: 1. In a wireless energy transmission system including a wireless energy receiving device and a wireless energy transmitting device, at least one of the wireless energy receiving device and the wireless energy transmitting device comprising: a first oscillator configured to output an in-phase (I) signal; a second oscillator configured to output a quadrature-phase (Q) signal having a 90-degree phase difference from the I signal, wherein each of the first and se…
