CONTACTLESS CHARGING APPARATUS FOR MAXIMALLY PROVIDING CHARGING EFFICIENCY TO A CHARGED DEVICE, A CONTACTLESS CHARGING SYSTEM, AND A CONTACTLESS CHARGING METHOD

摘要

PURPOSE: A contactless charging apparatus, a contactless charging system, and a contactless charging method are provided to charge terminals having various specifications with maximally efficient transmission efficiency by controlling the location and area of a primary coil.;CONSTITUTION: An AC-DC transformation unit(102) receives an external AC power source and outputs a direct current voltage. A DC-AC transformation unit(104) receives the direct current voltage and outputs an alternating current to the primary coil(120). A location driving unit(112) transfers the location of the primary coil according to the command of the first controller(110). An area control unit(114) controls the on-off of a switch and changes the area of the primary coil. A first communications unit(118) transmits and receives information to/from a second communication unit(220).;COPYRIGHT KIPO 2012
