The measurement method for deriving figure-of-merit(FoM) that is necessary to derive maximum power transfer efficiency in a short-range wireless power transfer system using magnetic field is presented. The FoM of the system is determined by coupling coefficient between transmitting and receiving coils and quality(Q)-factor of the transmitting and receiving coils. Therefore, measurement method of coupling coefficient and Q-factor is explained and the measured FoM is obtained using the results.
In the technical report, only two types of wireless power transfer systems using two coils and four coils are considered. |
