NON-CONTACT POWER FEEDING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power feeding system enabling continuous power feeding to a mobile body while protecting a voltage conversion part when abnormality occurs.SOLUTION: High-frequency current is fed to a power feeder cable 200 from a high-frequency power source 300. A pick-up part 20 includes a power receiving coil 21 where voltage is generated by electromagnetic induction due to interlinkage of magnetic flux generated around the power feeder cable 200. A current rectification part 30 rectifies output of the pick-up part 20. A voltage conversion part 40 convers a voltage value by switching output voltage at the current rectification part 30 by a transistor 43, and feeds direct current voltage after conversion to a load 101 on a mobile body 100. A control part 60 controls an operation of the voltage conversion part 40. The control part 60 is structured so as to stop the switching operation of the transistor 43 and feed the output voltage of the current rectification part 30 to the load 101 when abnormality occurs in at least either one of the mobile body 100 and a power feeding device 10.
