Abstract
A wireless power transmission apparatus includes a resonator configured to transmit power through a resonance with another resonator, a switch configured to connect the resonator to a power source, a setting unit configured to set a target amount of current to flow in the resonator, and a control unit configured to control the switch based on the target amount of current.
Claims24
A wireless power transmission apparatus comprising:
- a resonator configured to transmit power through a resonance with another resonator;
- a switch configured to connect the resonator to a power source;
- a setting unit configured to dynamically set a target amount of current to flow in the resonator based on at least one of data to be transmitted to the another resonator, an actual amount of current flowing in the resonator and a resonance waveform of the resonator;
- and
- a control unit configured to control the switch based on the target amount of current.
An energy charging apparatus comprising:
- an inductor configured to store energy;
- a switch configured to connect the inductor to a power source;
- a setting unit configured to dynamically set a target amount of energy to be stored in the inductor based on at least one of data to be transmitted to the resonator, an actual amount of current flowing in the resonator and a resonance waveform of the resonator;
- and
- a control unit configured to control the switch based on the target amount of energy.
A method of controlling a wireless power transmission apparatus comprising a resonator configured to transmit power through a resonance with another resonator, the method comprising:
- dynamically setting a target amount of current into flow into the resonator based on any one or any combination of a resonance waveform of the resonator, an actual amount of current flowing in the resonator, and data to be transmitted to the other resonator;
- and
- determining whether current is allowed to flow in the resonator based on a charging and discharging cycle of the resonator.
