一种基于磁耦合谐振式的高效率 双频无线能量传输系统
A dual-band wireless power transfer transmitting and receiving device with high efficiency
摘要
Abstract
In order to improve the efficiency of dual-band magnetic resonance wireless power transfer ( WPT) sys-tem,this paper presents a pair of dual-band transmitter and receiver at Industrial Scientific and Medical ( ISM) band.Firstly,the two different resonators of the transmitting end are fed by one feeding loop,which is the same as that of the receiving end.Power is transferred from the transmitter to the receiver at the operating frequency of the two resonators by magnetic resonance.Since the two resonators are both delivering power at their own resonant fre-quency,the efficiency of proposed WPT can reach impressive values at a relative long distance.A pair of prototype transmitter and receiver is implemented using printed circuit boards ( PCB) to validate the advance of the proposed scheme.Simulation and measurement results illustrate that the two operating frequencies of the WPT are 6. 78 MHz and 13. 56 MHz.The power transfer efficiencies reach their maximum value of 88. 5% and 56. 7% respectively when the distance is 60% of the overall dimensions.关键词
