1. A system for controlling the wireless charging power of electric vehicles and industrial equipment (hereinafter, collectively referred to as ‘electric vehicles’) in operation equipped with a pick-up, comprising:
a power supply segment including a power supply cable through which an alternating current flows and a power supply core composed of a ferromagnetic material for effectively transferring the power generated from the power supply cable to the pick-up system; an inverter having a wired connection to each of a plurality of the power supply segments and controlling the supply of AC current flowing through the power supply cables of the respective power supply segments; and a capacitor connected within the power supply cable and configured to cancel an inductance generated in the power supply cable, thereby reducing a withstand voltage requirement, wherein two or more inverters adjacent to each other share a power factor correction of 3-phase AC power.
