Power transmission control device, power transmitting device, non-contact power transmitting system, and electronic instrument
First Claim
1. A power transmission control device provided in a power transmitting device of a non-contact power transmission system, the non-contact power transmission system performing non-contact power transmission from the power transmitting device to a power receiving device via a primary coil and a secondary coil that are electromagnetically coupled, the power transmission control device comprising:
- an operation mode switch terminal that receives an operation mode switch control signal, the operation mode switch control signal switching an automatic mode to a switch mode, the power transmitting device starting normal power transmission in the automatic mode after installation of a power-receiving-side instrument that includes the power receiving device, in an area in which power transmitted via non-contact power transmission can be received, has been automatically detected, the power transmitting device supplying power to a load of the power-receiving-side instrument at the normal power transmission, and the power transmitting device starting the normal power transmission in the switch mode after an operation trigger switch has been turned ON;
an operation trigger terminal that receives an operation trigger signal, the operation trigger signal occurring due to an operation of the operation trigger switch; and
a power-transmitting-side control circuit that controls power transmission to the power receiving device and changes an operation mode of the power transmitting device based on the operation mode switch control signal.

Abstract
A power transmission control device used for a non-contact power transmission system includes an operation mode switching terminal that receives an operation mode switch control signal that switches a mode between an automatic mode and a switch mode, a power transmitting device starting normal power transmission in the automatic mode after installation of a power-receiving-side instrument that includes a power receiving device in an area in which power transmitted via non-contact power transmission can be received has been automatically detected, the normal power transmission supplying power to a load of the power-receiving-side instrument, and the power transmitting device starting the normal power transmission in the switch mode after an operation trigger switch has been turned ON, an operation trigger terminal that receives an operation trigger signal that occurs due to an operation of the operation trigger switch, and a power-transmitting-side control circuit that controls power transmission to the power receiving device and changes an operation mode of the power transmitting device based on the operation mode switch control signal.

16. A non-contact power transmission system performing non-contact power transmission, the system comprising:
-
a power transmitting device; and a power receiving device, the power transmitting device including a power-transmitting-side control device that controls power transmission to the power receiving device based on an induced voltage in a primary coil, the primary coil being electromagnetically coupled to a secondary coil, the power-transmitting-side control device including; an operation mode switch terminal that receives an operation mode switch control signal, the operation mode switch control signal switching an automatic mode to a switch mode, the power transmitting device set in the automatic mode automatically detecting installation of a power-receiving-side instrument that includes the power receiving device, performing an ID authentication process, and starting normal power transmission, and the power transmitting device set in the switch mode starting power transmission when an operation trigger switch has been turned ON, performing the ID authentication process, and starting the normal power transmission; an operation trigger terminal that receives an operation trigger signal, the operation trigger signal occurring due to an operation of the operation trigger switch; and a power-transmitting-side control circuit that controls power transmission to the power receiving device and changes an operation mode of the power transmitting device based on the operation mode switch control signal, the power receiving device including a power supply control section that controls power supply to a load, and a power reception control device that controls the power receiving device, the power-transmitting-side control circuit of the power transmitting device causing the power transmitting device to perform intermittent temporary power transmission when the automatic mode has been selected based on the operation mode switch control signal, and detecting installation of a power-receiving-side instrument that includes the power receiving device depending on whether or not ID authentication information has been received from the power receiving device that has received the intermittent temporary power transmission within a given period of time from a start time of the intermittent temporary power transmission, causing the power transmitting device to perform the normal power transmission to the power receiving device when the installation of the power-receiving-side instrument has been detected on condition that the ID authentication process has been completed successfully, causing the power transmitting device to perform the intermittent temporary power transmission when the ID authentication information has not been received from the power receiving device within the given period of time from the start time of the intermittent temporary power transmission or the ID authentication process has not been completed successfully; and the power-transmitting-side control circuit causing the power transmitting device to perform the intermittent temporary power transmission that enables the ID authentication process to the power receiving device when a switch provided in a power-transmitting-side instrument has been turned ON when the switch mode has been selected based on the operation mode switch control signal, performing the ID authentication process based on the ID authentication information when the ID authentication information has been received from the power receiving device that has received the intermittent temporary power transmission within a given period of time from a start time of the intermittent temporary power transmission, causing the power transmitting device to perform the normal power transmission to the power receiving device after the ID authentication process has been completed successfully, and causing the power transmitting device to return to an initial state when the ID authentication information has not been received from the power receiving device within the given period of time from the start time of the intermittent temporary power transmission or the ID authentication process has not been completed successfully, the power transmitting device waiting for the switch to be turned ON in the initial state without performing the intermittent temporary power transmission. - View Dependent Claims (17)
