Abstract

A power supply device is embedded in the longitudinal direction of a road and used for supplying a power to an on-line electric vehicle using magnetic induction. The power supply device includes a pair of split return cables, each split return cable being arranged in parallel at a distance from a power supply line in the horizontal direction of the power supply line, one ends of the split return cables being electrically connected to the other end of the power supply line, and the other ends of the split return cables being electrically connected to the power supply unit. Accordingly, the current from a power supply unit passes through the power supply line, branches off to the split return cables, and then flows to the power supply unit again, to thereby reduce EMF by canceling the EMF occurring at both sides of the power supply device.
