Abstract
Embodiments of magnetic field transfer circuits and methods for wirelessly charging electrical load herein. In one example, a magnetic field transfer circuit (MFCT) includes a first coil and a second coil. The first coil is configured to receive a first magnetic flux transmitted from a transmitter and convert the received magnetic flux to a current. The second coil is configured to transmit a second magnetic flux to a receiver based on the current.
Claims20
A magnetic field transfer circuit (MFTC), comprising:
- a first coil configured to receive a first magnetic flux transmitted from a transmitter and convert the received magnetic flux to a current;
- and
- a second coil configured to transmit a second magnetic flux to a receiver based on the current.
A method for wireless charging, comprising:
- receiving a first magnetic flux transmitted from a transmitter using a first coil;
- converting the received magnetic flux to a current;
- and
- transmitting a second magnetic flux to a receiver based on the current using a second coil.
