Wireless power transfer device for automatic logistics systems

Abstract

This invention relates to a wireless power transmission device that transmits power non-contactly to one or more transfer vehicles moving along a track via magnetic induction. The novel wireless power transmission device is characterized by placing the inverter on the side of the track, eliminating the need for extension cables and reducing costs. Furthermore, the input and output terminals of the inverter can be connected and disconnected via a connection unit. Thus, when an inverter malfunctions, the AS transfer vehicle to remove the faulty inverter and move it to a storage unit, then transfers a new inverter to the location of the faulty inverter, thereby achieving automatic maintenance.
