1Length of stationary object
If the distance between source resonator and target resonator increases, then the transmission distance is extended, but the power transmission efficiency degrades
Solution Approach 1:
A wireless power transceiver is introduced as an intermediary device positioned between the source resonator and target resonator. The transceiver includes a receiving resonator that captures power from the source resonator and a transmitting resonator that forwards power to the target resonator, effectively dividing the long transmission path into two shorter segments to maintain efficiency
Solution Approach 2:
The power transmission path is segmented into multiple stages: source resonator → receiving resonator (inbound power) → transmitting resonator → target resonator (outbound power). This segmentation allows each resonator pair to operate at optimal coupling conditions, preventing efficiency degradation over long distances
2Loss of energy
If coupling frequency is optimized to minimize reflected wave, then power transmission efficiency improves, but system complexity increases due to additional control mechanisms
Solution Approach 1:
A coupling controller implements feedback control by detecting the reflected wave characteristics and adjusting the coupling frequency accordingly. The controller minimizes reflected wave amplitude, power, or phase by dynamically tuning the coupling frequency, ensuring optimal power transfer while maintaining system stability
Solution Approach 2:
The coupling frequency is dynamically adjusted as a controllable parameter to optimize power transmission. By changing the coupling frequency based on reflected wave conditions, the system achieves maximum transmission efficiency without requiring complex structural modifications
