POWER FEED DEVICE AND METHOD FOR ACQUISITION OF FREQUENCY CHARACTERISTICS |
| 摘要 |
Inverter supplies an alternating current (AC) power of a constant voltage or a constant current to power supply coil while varying a drive frequency. Frequency characteristic acquisition unit acquires frequency characteristics of a current value associated with a current flowing through power supply coil that receives the supplied AC power, or a voltage value associated with a voltage applied to power supply coil. |

1. A power feed device comprising:
a power supply coil for supplying power to an external power reception coil by electromagnetic action; a power supply unit for supplying an alternating current (AC) power to the power supply coil, while varying a drive frequency; and an acquisition unit for acquiring frequency characteristics of a current value associated with a current flowing through the power supply coil, or a voltage value associated with a voltage applied to the power supply coil at a time when receiving the supplied AC power. |
