Abstract (in Japanese) (See Japanese page) 
(in English) Wireless power transfer technology has some problem for stable high-efficiency transmission. For resonance-coupled wireless power transfer, the efficiency might be frequently degraded by impedance mismatch. To solve this problem, impedance matching circuits separated from coupling elements are introduced for power transmitting and receiving units. By readjusting the impedance matching, the efficiency degradation is suppressed, even if the positions of power transmitting and receiving units are varied. The purpose of this study is to develop a dynamic impedance matching system for mobile wireless power transmission. Formulas for calculating the element values of the matching circuit were derived. An experimental dynamic matching circuit was designed and fabricated. The measurement results showed the validity of the dynamic matching system.
