“…A long with the continuous development of electronic technology, wireless power transfer technology has gradually become a popular research focus. Wireless power transfer (WPT) system is widely applied in various fields such as the powering of implantable devices, electronic equipment, and smart homes [1][2][3][4][5][6][7]. When powering small electronic devices, the gap between the receiving coil and transmitting coil of the WPT system leads to magnetic field leaking out of the working area, adversely causing negative effect on the system's transmission efficiency and electromagnetic environment.…”

A reactive power shielding structure working under 150 kHz for small electronic equipment was proposed to reduce the electromagnetic leakage of WPT system. First, the model of LCC-LCC compensation circuit was established. By ensuring transmission efficiency, a comprehensive analysis of nine sets of computational data results was conducted to select the scheme with the best shielding effect. The experimental results showed that the magnetic flux density attenuation was 27.82% at 41 mm transmission distance from the center under the optimal structure of 3 rings and 7 turns, inner diameter of 23 mm, and outer diameter of 35 mm. The transmission efficiency can reach 76.73%, which is only 1.32% lower than the situation without shielding. The proposed reactive power shielding structure can significantly reduce the magnetic flux density in the external area of the WPT system without affecting the transmission efficiency of the system.
