專業(yè)的設(shè)備處理高電壓能量收集

　　能量收集往往涉及權(quán)力清除涓涓細(xì)流從非常低的能量環(huán)境來源。對于這些應(yīng)用程序，設(shè)計人員專注于電路能夠轉(zhuǎn)換到最小的可用電壓電平的有用功率。與此相反，高能量的來源需要一類電路能夠有效地處理高電壓水平的能量傳感器，如太陽能電池板，熱電發(fā)電機(jī)，壓電設(shè)備。設(shè)計師可以使用從制造商包括線性技術(shù)中，半導(dǎo)體、羅姆半導(dǎo)體、意法半導(dǎo)體器件實現(xiàn)高效的高壓能量收集系統(tǒng)，德克薩斯文書，其中。

　　低能量的應(yīng)用，高效的能量收集芯片等先進(jìn)設(shè)備eh4205線性模塊，線性技術(shù)LTC3108、德克薩斯文書bq25570旨在清除功率從換能器產(chǎn)生有限的電壓水平低20 mV，最大值為6 V左右。在這些系統(tǒng)的核心，升壓轉(zhuǎn)換器帶來低電壓到有用的水平供電電路和充電超級電容器和電池。

　　High-energy sources and their respective transducers can produce output-voltage levels easily exceeding the maximum input range of these low-voltage devices. For example， solar panels such as the Phoenix Contact 2885456 module produce nearly 18 V output. Driven by high-amplitude vibrations in industrial applications and other high-energy environments， piezoelectric devices can achieve output levels in the tens of volts. Similarly， thermoelectric generators can produce similar voltage output levels when a sufficiently large temperature differential exists between the two sides of a TEG， although achieving that temperature differential can be a difficult task at best.
