Abstract
A power supply device comprises a capacitance (Ca) consisting of an overhead power line () and an electrode () extending in the longitudinal direction of the overhead power line () via an insulator (), an inductance (La) connected in parallel with the capacitance (Ca), and an output portion () led out from both ends of a parallel circuit including the capacitance (Ca) and the inductance (La). The parallel circuit is operated as a parallel resonant circuit and power is supplied from the output portion (), thereby obtaining a compact and simple structure and improving power supply efficiency to a load as compared with a conventional power supply device.
