1. A wireless power transmission system comprising:
- 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, wherein an effective inductance of the source coil is increased by the two intermediate coils, and thus, a coupling coefficient between the source coil and the load coil is increased.
