Considering to apply the wireless power transfer with MRC into the battery chargers for electrical
vehicles (EVs), the coils for the transmitting side and receiving side are planted on the ground in
parking areas, and underneath of EVs, respectively. This technology brings convenience to users
because users are not required to charge the battery with electrical cables [9].
In the wireless power transfer system with the MRC, the size of the transmitting coils depends on
the transmitting frequency [10]. Thus, the wireless power transfer systems are expected to operate in
high-frequency in order to achieve a high power density. Moreover, MRC should be operated in
industrial scientific medical (ISM) band such as 13.56 MHz and 27.12 MHz because noise from the
wireless power transfer systems is prohibited to influence the operation of neither the electronic
devices nor the radio communication equipment.
