説明

<p>To achieve the wireless power feeding through the metal barrier without penetration of the wall by the wire feed through, it is necessary to avoid the eddy current generated on the metal surface. This paper presents a proposal for a pseudo-resonator method based on magnetic resonance coupling that uses the metallic structure to resemble the power relay resonator. To demonstrate the principle of the pseudo-resonator method, the four coils wireless power transfer system via magnetic resonance coupling was used in the 0.1 and 5.0-mm-thick stainless steel hollow tube. Results show that the efficiency of power transfer for the pseudo-resonator method was constant at 83% and 64% with the axial distance between the TX and RX resonator. Results revealed that the pseudo-resonator method has an advantage in wireless power transfer through the metal structure.</p>
