摘要
随着时代的发展,科技的进步,人们的生活中被电器充满,许多能源被电能所替代,人们越来越离不开电力。日常生活中,人们做饭使用电磁炉,洗衣服用洗衣机,通讯设备用手机,就连购物也是用电脑网购,这些设备的使用都要用电来运转。2007年,麻省理工学院成功的用无线能量传输技术点亮了一个60W的灯泡。这就是世界上第一次现代意义上的无线供电。发射线圈(coil)和接收线圈之间的距离约2m,线圈谐振频率为10MHz。虽然这个距离很短,但在强电领域,以谐振电磁耦合技术向无线能量传输梦想迈出了坚实一步。
With the development of the times and the progress of science and technology,our life is full of electrical appliances,and many energy sources are replaced by electric energy.We can not do without one thing more and more,that is,electric power.In our daily life,we use electromagnetic ovens for cooking,washing machines for laundry,mobile phones for communication equipment,and even for shopping,we use computers to buy online.All these devices are operated by electricity.In 2007,MIT successfully lit a 60-watt light bulb with wireless energy transfer technology.The distance between the transmitting coil and the receiving coil is about 2 meters,and the resonance frequency of the coil is 10 MHz.Although this distance is very short,it is also considered that since Tesla,in the field of strong electricity,the resonant electromagnetic coupling technology has taken a solid step towards the dream of wireless energy transmission.
