- the non-contact power transmission device does not require a circuit like the input connection circuit of Patent Document 1. Therefore, it is possible to appropriately protect the communication circuit during power transmission and to avoid a decrease in signal level during communication.
- the non-contact power transmission device is a power receiving device, and performs non-contact power transmission and communication with a power transmission device as a counterpart device.
- the non-contact power transmission apparatus 10 includes a power transmission antenna (non-contact power transmission unit) 20 and a power receiving circuit (power transmission circuit) 30 connected to the power transmission antenna 20.

- the communication antenna 40 is a loop antenna, but may be a coil antenna.
- the communication antenna 40 according to the present embodiment is surrounded by the power transmission antenna 20.

That is, the control circuit 70 controls the cutoff circuit 50 so as to cut off the communication antenna 40 and the communication circuit 60 when the level of the transmitted power exceeds the first threshold. On the other hand, the control circuit 70 controls the cutoff circuit 50 so as to release the cutoff when the level of transmitted power falls below a second threshold that is lower than the first threshold.

Specifically, the control circuit 70 shuts off the communication antenna 40 and the communication circuit 60 when the output of the rectifier circuit 32 (the voltage value of the rectified power) exceeds the first threshold. The circuit 50 is controlled. On the other hand, the control circuit 70 controls the cutoff circuit 50 so as to release the cutoff when the output of the rectifier circuit 32 falls below the second threshold.
- the first threshold value is determined based on the withstand voltage value of the communication circuit 60
- the second threshold value is a voltage supplied to the load unit 34 when the impedance of the load unit 34 is minimum. It is determined based on the value.
- the output of the rectifier circuit 32 is also below the second threshold value, so that the cutoff by the cutoff circuit 50 is released and the communication circuit 60 is connected to the communication antenna 40. Communication takes place.

Further, in the present embodiment, the control circuit 70 determines that the power transmission has started when the power level to be transmitted exceeds a predetermined level, and the cutoff circuit 50 is connected between the communication antenna 40 and the communication circuit 60.
- the shut-off circuit 50 is controlled to shut off, the present invention is not limited to this.
