摘要： There is provided a control device that estimates power transmission efficiency between a power transmitting unit and a power receiving unit. The power transmitting unit includes a first coil and a first capacitor connected to the first coil in parallel or in series. The power receiving unit includes a second coil and a second capacitor connected to the second coil in parallel or in series and receives electric power from the power transmitting unit through a coupling between the first coil and the second coil. The control device includes an estimator. The estimator compares a detected value of a first voltage or a first current at a first location in the power transmitting unit with a detected value of second voltage or second current at a second location in the power receiving unit and estimates the power transmission efficiency from the power transmitting unit to the power receiving unit.

摘要： According to one embodiment, a wireless electric power transmission device supplies electric power, transmitted wirelessly from a first device, to a load circuit. The device includes a power receiving resonance unit, a detecting unit which detects electric power information corresponding to the electric power supplied to the load circuit, and a control unit. The control unit determines whether to adjust at least one of a resonant frequency of the power receiving resonance unit, an output frequency of an alternating current power supply of the first device, and a resonant frequency of a power transmitting resonance unit of the first device, on the basis of a relationship in terms of magnitude between first electric power information when the impedance is a first impedance and second electric power information when the impedance is a second impedance.
