| Abstract | In the Impedance Matching (IM) condition of Wireless Power Transfer (WPT), series resonant and strong coupling structures have been widely studied which operate at an optimal parameter, a resistive load, and the high resonant frequency of greater than 1 MHz. However, i) The optimal parameter (particular value) limits the design, ii) the common loads are complex, iii) The high frequency RF sources are usually inefficient. This paper presents a modified parallel resonant structure that can operate at a low frequency of 15 kHz without an optimal parameter under the IM condition with a complex load, and the calculated efficiency is equal to 71.2 % at 5-cm transfer distance. |
