射頻感應(yīng)充電評(píng)估套件切斷電線

　　自從特斯拉1901年底在大西洋輸電的不幸嘗試中，無(wú)線傳輸電力已經(jīng)走了很長(zhǎng)的路。今天你可以把手機(jī)扔到充電板上，然后用無(wú)線方式充電。特斯拉會(huì)感到失望，因?yàn)樗荒芄ぷ鲙桌迕?，而不是幾千英里。但是，與他的權(quán)力塔不同，它運(yùn)作良好。

　　乍看之下，感應(yīng)充電似乎是一種浪費(fèi)電線的方法。但是電感耦合諧振系統(tǒng)達(dá)到了90%以上的效率，感應(yīng)充電在商業(yè)、工業(yè)甚至汽車(chē)應(yīng)用中得到廣泛的認(rèn)可。Cymbet的CBC-EVAL-11射頻感應(yīng)充電評(píng)估套件（參見(jiàn)圖1）演示了如何輕松地你可以利用這個(gè)源于RFID、傳感器的能量，和無(wú)線網(wǎng)絡(luò)的應(yīng)用。本文將介紹試劑盒并對(duì)其操作進(jìn)行評(píng)估。

　　The Cymbet kit consists of an inductive wireless transmitter board operating at 13.56 MHz and an inductive wireless receiver module which charges a thin-film storage battery. Both boards include large printed planar inductors as well as variable capacitors that form resonant tank circuits. The transmitter board is USB powered， while the receiver board contains an EnerChip? CBC3150 3.3 V/50 μA thin-film battery with integrated power management.
