1. An electric power supply apparatus for external devices of an overhead hoist transport system using a high frequency track cable, the electric power supply apparatus supplying power to an external device in an overhead hoist transport system that includes a transport track installed along a preset path on a ceiling at a work site, a carriage installed to be movable along the transport track, high frequency track cables being a wire through which a high frequency current flows and disposed adjacently in parallel in the longitudinal direction of the transport tracks, a cable holder extending from a side of the transport track and gripping the high frequency track cables using a side, and at least one external device installed on the other side of the transport track, comprising:
a wireless power generation module installed at least at a side of the cable holder adjacent to the external device and supplied with inductive power transmitted by magnetic induction through a magnetic field generated from the high frequency track cable; and
a power conversion module converting inductive power supplied to the wireless power generation module to a preset voltage for operating the external device and then supplying the inductive power to the external device.
