Abstract

Quality factor is the most essential parameter in the concept of the mid-range wireless power transmission. The theoretical formula of the transmission efficiency was redefined as a function of coupling coefficient and quality factor. This redefinition enables simple comparison between the conventional close-range electromagnetic induction transmission and the mid-range transmission. The realizable quality factor was precisely analyzed by the additional calculations of the wire cover loss and the capacitor loss. And the actual transmission system was developed. It verified the redefined efficiency formula and the new calculation method of quality factor.
