WIRELESS POWER COMMUNICATION SYSTEM CAPABLE OF REDUCING A MAGNETIC FIELD LEAKAGE, A WIRELESS POWER RECEIVER, AND A WIRELESS POWER SUPPLY DEVICE USED IN THE SAME

摘要

PURPOSE: A wireless power communication system, a wireless power receiver, and a wireless power supply device used in the same are provided to minimize a leakage of magnetic fields which are extended to a second core from a first core by properly arranging the first core and the second core.;CONSTITUTION: A first core(120) and a second core(220) are arranged by facing each other. The first core is built in a power supply device. The first core comprises a central protrusion(121) and surrounding protrusions(122,123). The first core has a pot shape which includes the central protrusion and the surrounding protrusions which are consecutively projected along the circumferential direction of the core. The second core is installed inside of a power receiver. The second core comprises a central protrusion(221) and surrounding protrusions(222,223).;COPYRIGHT KIPO 2012
