Non-contact power transmitting device
First Claim
1. A non-contact power transmitting device, comprising:
- a power receiving device including a rectification circuit, a voltage converting circuit, a storage circuit in which an authentication pattern is stored, and a switching circuit, the switching circuit being configured to connect or disconnect the voltage converting circuit to or from a load circuit according to the authentication pattern stored in the storage circuit; and
a power transmitting device including a power transmitting circuit, a detection circuit configured to detect a current that is supplied to the power transmitting circuit, and a determination circuit configured to compare the detected current value with a threshold current to determine whether the load circuit of the power receiving device is connected or disconnected, the power transmitting device being configured to transmit power to the power receiving device in a non-contact manner.

Abstract
A non-contact power transmitting device includes a power receiving device that includes a rectification circuit, a voltage converting circuit, and a switching circuit for connecting or disconnecting the voltage converting circuit to or from a load circuit, and a power transmitting device that includes a power transmitting circuit, a detection circuit that detects a current that is supplied to the power transmitting circuit, and a determination circuit that compares the detected current value with a threshold current set in advance, and determines whether the load circuit of the power receiving device is in contact with the power transmitting device, where the power transmitting device transmits power to the power receiving device in a non-contact manner.

9. A non-contact power transmitting device, comprising:
-
a power receiving device including a rectification circuit, a voltage converting circuit, a switching circuit for connecting or disconnecting the voltage converting circuit to or from a load circuit according to a first pattern, and a storage circuit configured to store the first pattern; and a power transmitting device including a power transmitting circuit, a detection circuit configured to detect a current that is supplied to the power transmitting circuit, and a determination circuit configured to compare the detected current value with a threshold current to determine whether the load circuit of the power receiving device is connected or disconnected and to compare a second pattern of changes in the detected current value with the first pattern to determine whether or not the power receiving device is correctly mounted on the power transmitting device, the power transmitting device being configured to transmit power to the power receiving device in a non-contact manner. - View Dependent Claims (10, 11, 12, 13, 14)
