<p>Provided is a contactless power supply system which supplies electric power contactlessly to a transfer carriage through a pair of power supply lines (21) provided along the rail of the transfer carriage. The system comprises: an EI core (31b) which is secured to and placed partway on the power supply lines (21); a coil (314) wound around the EI core (31b); and a capacitor (31a) connected at both ends of the coil (314). The coil (314) is coupled with the power supply line (21) via electromagnetic induction with the axial direction of the coil (314) intersecting with the extending direction of the power supply line (21). Viewed from the power supply point, the impedance of an inductance minimizing unit (31) indicates capacitative reactance.</p> |
