Abstract
Official abstract text for this publication.
A wireless power transmitter according to some embodiments can include a transmitter circuit configured to be coupled across a series coupled capacitor and transmit coil; and a controller coupled to a node between the capacitor and the transmit coil, the controller configured to adjust a reactive energy in the series coupled capacitor and transmit coil in response to a change in operating frequency.
First claim
Opening claim text (preview).
What is claimed is: 1 . A wireless power transmitter, comprising: a transmitter circuit configured to be coupled across a series coupled capacitor and transmit coil; and a controller coupled to a node between the capacitor and the transmit coil, the controller configured to adjust a reactive energy in the series coupled capacitor and transmit coil in response to a change in operating frequency. 2 . The transmitter of claim 1 , wherein the reactive energy can be adjusted within a cycle. 3 . The transmitter of claim 1 , wherein frequency shift keying data transmission can be used. 4 . The transmitter of claim 1 , wherein the reactive energy is adjusted to be appropriate for a new operating frequency. 5 . The transmitter of claim 1 , wherein the reactive energy is adjusted by adjusting a voltage at the node. 6 . The transmitter of claim 1 , wherein the reactive energy is adjusted by adjusting a charge on the capacitor. 7 . The transmitter of claim 1 , wherein the reactive energy is adjusted by adjusting a magnetic flux of the transmit coil.
