style="text-indent:25px">逆變器是一種DCtoAC的變壓器，它其實(shí)與轉(zhuǎn)化器是一種電壓逆變的過(guò)程。轉(zhuǎn)換器是將電網(wǎng)的交流電壓轉(zhuǎn)變?yōu)榉€(wěn)定的12V直流輸出，而逆變器是將Adapter輸出的12V直流電壓轉(zhuǎn)變?yōu)楦哳l的高壓交流電；兩個(gè)部分同樣都采用了用得比較多的脈寬調(diào)制（PWM）技術(shù)。其中心部分都是一個(gè)PWM集成控制器，Adapter用的是UC3842，逆變器則采用TL5001芯片。TL5001的工作電壓范圍3.6～40V，其內(nèi)部設(shè)有一個(gè)誤差放大器，一個(gè)調(diào)節(jié)器、振蕩器、有死區(qū)控制的PWM發(fā)生器、低壓保護(hù)回路及短路保護(hù)回路等。</p><p style="text-indent:25px">逆變器作用：有了逆變器，就可利用直流電(蓄電池、開(kāi)關(guān)電源、燃料電池等)轉(zhuǎn)換成交流電為電器提供穩(wěn)定可靠得用電保障，如筆記本電腦、手機(jī)、手持PC、數(shù)碼相機(jī)以及各類儀器等;逆變器還可與發(fā)電機(jī)配套使用，能有效地節(jié)約燃料、減少噪音;在風(fēng)能、太陽(yáng)能領(lǐng)域，逆變器更是必不可少。小型逆變器還可利用汽車(chē)、輪船、便攜供電設(shè)備，在野外提供交流電源。逆變器有著普遍的用途，它可用于各類交通工具，如汽車(chē)、各類艦船以及飛行器，在太陽(yáng)能及風(fēng)能發(fā)電領(lǐng)域，逆變器有著不可替代的作用。隨著技術(shù)的發(fā)展，用戶在移動(dòng)中需要使用的電子設(shè)備越來(lái)越多，逆變器能夠隨時(shí)為這些設(shè)備提供充足的交流電源，為用戶提供一個(gè)較好的解決方案。內(nèi)置過(guò)載、短路、過(guò)壓、欠壓、過(guò)溫等保護(hù)功能，可靠性高。</p><div
