WIRELESS POWER TRANSMISSION SYSTEM FOR TRAM VEHICLE

摘要

The present invention relates to a wireless power transmission system for a tram vehicle, which is configured to comprise: an inverter used for electricity feeding as a power supply source which supplies power that is required for driving the tram vehicle; an electricity feeding line, wherein an electromagnetic induction energy is generated by a high frequency alternating current supplied from the inverter used for electricity feeding; a current collecting module (Pick-up) where the electromagnetic induction energy of the electricity feeding line is collected to be converted into electric energy, and which is provided on the tram vehicle; and a voltage regulator to supply the electrical energy delivered from the current collecting module, whereby the voltage is adjusted, to vehicle driving means. According to the present invention, the wireless power transmission system is applied to the urban type wireless tram vehicle, thereby the maintenance cost is incurred in the contact electricity feeding method of the contact power supply system used in existing high sky rail or a third rail, whereas the electric vehicle wire is connected like a spider′s web downtown so that the risk of an electric shock accident caused by the electric vehicle wire or the third rail may be eliminated, and the weather such as heavy rain, strong winds, etc. may not affect the driving of the tram vehicle, and large capacity power can be actively supplied, thereby the durability of the battery for the tram vehicle may be extended.
