A simple design method for the resonator-coupled wireless power transfer system is proposed on the basis of the BPF theory. Three parameters of the constituting resonators are obtained in advance to design a BPF, which include the resonant frequency, coupling coefficient between adjacent resonators, and the external Q of the outermost resonators. The design is carried out adjusting those parameters to cope with a 2-stage BPF made of two direct coupled resonators. Since the present design theory can be applied for any resonators as long as their resonant frequency is chosen the same, it has a wide range of practical application. The adopted design example is a magnetically coupled 2-stage resonator system proposed by MIT group, since it is most popular, but any usable design theory has not been presented so far.
