ACTIVE TYPE WIRELESS POWER TRANSMISION SYSTEM

摘要

The present invention relates to an active wireless power transmission method, and more specifically, to an active wireless power transmission method which can prevent devices of an on-board unit installed in a rolling stock from burning when a load suddenly reduces, by adjusting electric power supplied by a wayside units according to the load of the rolling stock. To achieve above purpose, provided is the active wireless power transmission system comprising a wayside unit including a substation, an inverter, and a feeder line; and an on-board unit including a pick-up module receiving power from the feeder line, and a regulator. The active wireless power transmission system is characterized in that an output of the inverter is controlled according to strength of an output current of the regulator, and the inverter includes an operation device which calculates an inverter output command value in order to control the output of the inverter to correspond to the strength of the output current of the regulator.
