Wireless Power Supply Device and Wireless Power Supply System |
| 摘要 |
A wireless power supply device includes a resonance circuit including a coil and a capacitor, a power supply portion that supplies AC power to the resonance circuit based on a drive signal having a prescribed drive frequency, and a controller that substantially matches the phase of the drive signal and the phase of oscillation of the resonance circuit by switching the direction of a current that flows into the coil. |
