Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we focused on the load independence of the wireless power transfer circuit and examined the circuit design that can easily CV/CC charging. The analyzed circuit is a multi-resonant circuit in which the primary side and the secondary side are both series resonant. We examined a design method in which the operating frequency range of CV/CC charging is 79 -90 kHz and clarified that it cannot be realized unless the coupling coefficient is 0.298 or less. Also, the load-independent mechanism is examined, and we found that the change in the input effective power contributes and that the input power factor is always 1 for CC charging.
