WIRELESS POWER TRANSFER SYSTEM |
| 摘要 |
A wireless power transmission system according to an exemplary embodiment of the present invention includes: a source coil at a primary side; a load coil at a secondary side; and at least two intermediate coils coupled with each other in an insulated manner with a predetermined turn ratio with respect to the source coil. An effective inductance of the source coil is increased by the at least two intermediate coils and thus a coupling coefficient between the source coil and the load coil is increased. |
