<p>PROBLEM TO BE SOLVED: To provide a non-contact power supply device which is economical and efficient, has high reliability, and can supply a prescribed voltage to a load. SOLUTION: A feeder 200 comprises mainly a feeder laid along a moving route of a mobile unit 300. A high frequency power supply 100 applies an AC voltage to the feeder. A pickup 310 is attached to the mobile unit 300. The pickup 310 has a secondary winding 312 which is magnetically coupled with the feeder and comprises a transformer. The secondary winding 312, a load R on the mobile unit of a feeding object, and a capacitor C4 are connected in series to each other and comprise a series resonance circuit which is tuned with a fundamental wave frequency of an inverter 110 in the high frequency power supply 100 to resonate.</p> |
