NON-CONTACT POWER SUPPLY DEVICE |
| 摘要 |
A non-contact power supply device, which supplies electric power to a power reception coil from a power transmission coil in a non-contact manner, includes a power transmission coil, a power transmission circuit switchably coupling a voltage source to the power transmission coil, the power transmission circuit configured to resonate at a fundamental frequency, and a serial LC resonant circuit in parallel with the power transmission coil, and configured to resonate at a frequency of a harmonic wave of the fundamental frequency. The non-contact power supply device suppresses a harmonic wave noise by providing a resonant circuit that resonates at a specific harmonic wave. |
