<p>PROBLEM TO BE SOLVED: To provide a non-contact feeding device which can reduce the voltage drop caused by a reactance, having its origin in the inductance of the primary- side conductor of the non-contact feeding device. SOLUTION: A non-contact feeding device is constituted for supplying electric power to a carrier side from its primary-side conductor 2, connected to a power source 1 in a non-contacting state by means of a secondary-side pickup coil 3 installed to the carrier by utilizing the electromagnetic conduction phenomenon. In order to compensate a reactance L2 of the coil 3, a capacitor 4 is connected in series with the coil 3, and both terminals of the capacitor 4 are connected to a load 5. Then, the reactance L2 of the coil 3 and the capacitance C2 of the capacitor 4 are set so as to satisfy a relation,ωL2 1>1/(ωC2 ), whereωrepresents the angular frequency of the power source 1.</p> |
