NON-CONTACT CHARGING SYSTEM

摘要

PURPOSE: A contactless charging system is provided to efficiently control power by executing power transmission and data communications only when a contactless power receiver is installed on a contactless power transmitter. CONSTITUTION: A first side core part(110) includes a first and a power transmitting core. An ID confirmation part(120) senses the load change of the first side core part. A wireless power transmission control part(130) controls a driving driver(150) according to the determination result of the ID confirmation part. A switching control part(140) controls the switching operation of a first and a second switch. A driving driver controls the operation of a serial resonant converter according to the intensity of a radio power signal. A feedback circuit part extracts the code data of an AC signal from a DC signal which is applied to a first side core part.
