<p><P>PROBLEM TO BE SOLVED: To provide a power supply system which can improve reliability compared with that of a conventional system, and can reduce costs. <P>SOLUTION: In the power supply system, a fixed body 10 comprises a power transmission coil 14 fed with AC power, a capacitor 15 connected to the power transmission coil 14 in series thereto, and an AC power supply 11 which feeds power to the power transmission coil 14 and the capacitor 15. A movable body 20 comprises a power receiving coil 21 which receives power form the power transmission coil 14 by mutual induction operation by being arranged at the power transmission coil 14 in an opposing state with a decorative plate 3 sandwiched therebetween and in a non-contact manner, and a magnetic body 22 which changes the inductance of the power transmission coil 14 by being arranged in the vicinity of the power transmission coil 14. In a state that series resonance conditions of the power transmission coil 14 and the capacitor 15 are satisfied by changing the inductance of the power transmission coil 14 by making the magnetic body 22 approximate the power transmission coil 14, power from the AC power supply 11 is fed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
