POWER SUPPLY APPARATUS, POWER COLLECTION APPARATUS AND POWER TRANSMISSION APPARATUS FOR MAXIMIZE POWER TRANSMISSION EFFICIENCY

摘要

PURPOSE: A power supply apparatus, a power collection apparatus and a power transmission apparatus are provided to maximize power transmission efficiency. CONSTITUTION: A current collecting unit(210) is magnetically coupled with a feeder(300). A current sensor(220) senses the current generated from the current collecting unit. An information transfer part(230) sends current information to the feeder. A current supply unit(310) includes a feeding core(312), and a feeding cable(314). An information receiving part(320) receives a first and second current information from the information transfer part. A control unit(340) adjusts a driver(330) according to the current information.
