Vehicle, ground power supplying apparatus, and noncontact power supplying system

A control apparatus for a power receiver which wirelessly receives electric power from a power transmitter. The control apparatus being configured to execute a restriction process that restricts received power by PWM control depending on an amount of the received power. The restriction process comprises calculating an increase gap which is a difference between an initial received power and a local maximum value of the received power with respect to a change in a duty in the PWM control, starting the PWM control when a first value which is a value obtained by adding the increase gap to a current received power exceeds a second value which is a value obtained by subtracting a predetermined margin from an upper limit of the received power, and increasing the duty until the received power becomes lower than the initial received power when starting the PWM control.

Control apparatus, control method, and non-transitory computer readable recording medium

An elevating operation apparatus includes: an obtaining device configured to obtain a first information and a second information, wherein the first information indicates whether or not one vehicle, which has a power receiving unit for wireless electric power supply, includes an elevating mechanism for moving the power receiving unit in a height direction of the one vehicle, and the second information indicates whether or not a power supply apparatus, which is installed outside the one vehicle and which has a power transmitting unit for wireless electric power supply, includes an elevating mechanism for moving the power transmitting unit in the height direction; and a determining device configured to determine to move at least one of the power receiving unit and the power transmitting unit in the height direction on the basis of the first information and the second information.
