Aiming at the problem of electricity conductor is increasing in the family,Sthe design ofSwireless power transmission systemSwith aSTesla coilSas the core.Tesla coil as wireless power transmission device, the receiving device is used to produce magnetic resonance (NMR) with a wireless power transmission.The experimental results show that,the power receivingSportion of theSsystemSnear theSpowerStransmission antennais about 10S~ 20cm position,SreceivingSmaximum power can reachStens of watts.In aSlocation away from theStransmitting antennaSis about 10S~ 15m,Sthe receivedpower of up toSa few tenths ofStile.So,Sin the 10cmS~ 10m rangeSto meet the smallSpower electric appliancesS basicelectricity requirement.
