通過脈沖能量收集供電電路

　　脈沖能量采集應(yīng)用程序?qū)⒛芰棵}沖轉(zhuǎn)換為足夠的功率，用于操作諸如無線開關(guān)、無線數(shù)據(jù)記錄器、遠(yuǎn)程控制等簡(jiǎn)單電路。建立這些設(shè)計(jì)，工程師可以利用各種可用的超低功耗集成電路和能源生產(chǎn)商包括EnOcean，線性技術(shù)，Linx技術(shù)，集成，測(cè)試專業(yè)，芯片技術(shù)，美迪科技、羅姆半導(dǎo)體、Schurter、Silicon Labs的換能器，德克薩斯文書，其中。

　　能量收集應(yīng)用程序通常依賴于清除流能量從身體發(fā)熱，振動(dòng)，或周圍的RF一方面或從能源如太陽能、風(fēng)能提取功率、等。在這種情況下，獲得持續(xù)的能源，無論是低或高能量，通常可以確保連續(xù)或接近連續(xù)運(yùn)行的電路。

　　Pulse harvesting， however， draws power from bursts of energy associated with a button push， sudden vibration， or other short-lived energy source. Outside of the pulse event itself， this approach leaves circuits with no additional power source beyond what excess energy they can store from pulse events. Despite these challenges， engineers have applied this approach to applications ranging from basic momentary pushbutton switches to complex wireless monitoring systems powered by the high-energy vibrations of railroad car wheels running across its tracks.
