Abstract
According to one embodiment, a wireless power transmission system includes: a power transmission device and a power reception device. The power transmission device includes an AC power generation circuit; first circuits connected to the AC power generation circuit; and power transmission resonators. The power reception device includes: power reception resonators, second circuits each connected to different one of the plurality of power reception resonators and a rectifier circuit. An absolute value of an open-circuit output reverse voltage gain in an F matrix of each of the plurality of first circuits is less than 1, and an absolute value of a short-circuit output reverse current gain in an F matrix of each of the plurality of second circuits is less than 1.
