一、車載逆變器有什么用

車載逆變器是一種方便的車用電源轉換器，開車外出工作或外出旅游時，可以用車載逆變器連接汽車蓄電池，帶動電器及各種工具工作。車載逆變器的作用主要就是電源轉換，可以將將汽車內的12V直流電，通過智能芯片轉變為家用220V交流電，供一般電器使用，有了車載逆變器，車主可以在汽車上加裝許多用電設備，就相當于家用的插排一樣，車主可以在車內進行手機充電，使用筆記本和游戲機以及電動工具等，相比點煙器的小電源來說，使用更加方便，而且還不用擔心電壓過大從而導致點煙器電源失效。如果您有在車上使用各種電器的需求，可以買車載逆變器幫助實現，購買時，注意選一個靠譜的車載逆變器品牌廠家。

二、車載逆變器對車有傷害嗎

一(yi)般情況，正常(chang)使(shi)用車(che)(che)(che)載(zai)逆變器(qi)對(dui)汽(qi)(qi)車(che)(che)(che)是(shi)沒有(you)(you)損害(hai)的(de)，不(bu)過(guo)如果(guo)使(shi)用不(bu)當的(de)話，可能會對(dui)汽(qi)(qi)車(che)(che)(che)電(dian)(dian)(dian)瓶造(zao)(zao)(zao)成(cheng)一(yi)定(ding)的(de)傷(shang)(shang)害(hai)：1、比(bi)如在車(che)(che)(che)輛停車(che)(che)(che)之后使(shi)用車(che)(che)(che)載(zai)逆變器(qi)為(wei)車(che)(che)(che)載(zai)電(dian)(dian)(dian)器(qi)供電(dian)(dian)(dian)，如果(guo)沒有(you)(you)啟動發動機，會造(zao)(zao)(zao)成(cheng)汽(qi)(qi)車(che)(che)(che)蓄電(dian)(dian)(dian)池(chi)的(de)虧電(dian)(dian)(dian)，從而對(dui)汽(qi)(qi)車(che)(che)(che)蓄電(dian)(dian)(dian)池(chi)造(zao)(zao)(zao)成(cheng)損害(hai)。2、另外(wai)，市場上存在一(yi)些“小(xiao)作坊”式的(de)生產廠家，這些小(xiao)廠家為(wei)了(le)降低生產成(cheng)本，節約了(le)很多關(guan)鍵的(de)器(qi)件，如過(guo)載(zai)保(bao)護(hu)(hu)、欠壓保(bao)護(hu)(hu)、過(guo)流保(bao)護(hu)(hu)、高(gao)壓保(bao)護(hu)(hu)以及高(gao)溫(wen)保(bao)護(hu)(hu)等，這種(zhong)劣質車(che)(che)(che)載(zai)逆變器(qi)可能會對(dui)汽(qi)(qi)車(che)(che)(che)造(zao)(zao)(zao)成(cheng)傷(shang)(shang)害(hai)。3、還有(you)(you)就是(shi)，如果(guo)逆變器(qi)的(de)啟動電(dian)(dian)(dian)流大于電(dian)(dian)(dian)池(chi)的(de)CCA，那么(me)電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)壓就會“無(wu)法(fa)保(bao)持(chi)”，在啟動的(de)瞬間就會大幅度(du)下降。這個時刻對(dui)電(dian)(dian)(dian)池(chi)的(de)健康極為(wei)不(bu)利(li)，如果(guo)經常(chang)執(zhi)行此循環，則電(dian)(dian)(dian)池(chi)壽命將(jiang)受到顯著影響。

四、車載逆變器功率怎么選

車(che)載(zai)(zai)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)的(de)功(gong)(gong)(gong)(gong)(gong)率(lv)大(da)(da)小應(ying)該根據實際需要(yao)來選(xuan)(xuan)擇。通(tong)常情況(kuang)下(xia)，我們可以(yi)(yi)通(tong)過以(yi)(yi)下(xia)簡單的(de)公式計(ji)算：所需功(gong)(gong)(gong)(gong)(gong)率(lv)=使用(yong)設(she)備最大(da)(da)功(gong)(gong)(gong)(gong)(gong)率(lv)×系數(shu)，其(qi)中系數(shu)有兩個：1.5和2：系數(shu)1.5適用(yong)于阻性負(fu)(fu)載(zai)(zai)，如電(dian)(dian)熱(re)毯、電(dian)(dian)暖氣、電(dian)(dian)爐等；系數(shu)2適用(yong)于感性負(fu)(fu)載(zai)(zai)，如液(ye)晶電(dian)(dian)視機(ji)(ji)、電(dian)(dian)冰箱、電(dian)(dian)腦(nao)等。例如，如果(guo)你想用(yong)車(che)載(zai)(zai)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)驅動一臺功(gong)(gong)(gong)(gong)(gong)率(lv)為800W的(de)電(dian)(dian)視機(ji)(ji)，那(nei)么需要(yao)選(xuan)(xuan)擇的(de)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)功(gong)(gong)(gong)(gong)(gong)率(lv)應(ying)該為：所需功(gong)(gong)(gong)(gong)(gong)率(lv)=800W×2=1600W，因為還需要(yao)使用(yong)其(qi)他(ta)電(dian)(dian)器(qi)(qi)(qi)(qi)，以(yi)(yi)及考慮一些冗余(yu)，因此至(zhi)少要(yao)2000W的(de)車(che)載(zai)(zai)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)。在選(xuan)(xuan)擇逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)功(gong)(gong)(gong)(gong)(gong)率(lv)時，首先要(yao)考慮用(yong)途，如果(guo)只是為了充電(dian)(dian)或使用(yong)小功(gong)(gong)(gong)(gong)(gong)率(lv)設(she)備，那(nei)么功(gong)(gong)(gong)(gong)(gong)率(lv)較小的(de)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)就(jiu)可以(yi)(yi)滿足需求；如果(guo)想要(yao)使用(yong)電(dian)(dian)視機(ji)(ji)、空(kong)調等功(gong)(gong)(gong)(gong)(gong)率(lv)較大(da)(da)的(de)設(she)備，就(jiu)需要(yao)選(xuan)(xuan)擇功(gong)(gong)(gong)(gong)(gong)率(lv)大(da)(da)的(de)車(che)載(zai)(zai)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)。

五、車載逆變器的工作原理是什么

一般的車(che)載逆變器主要由逆變橋(qiao)、濾波電(dian)(dian)(dian)(dian)路、控制(zhi)電(dian)(dian)(dian)(dian)路、振(zhen)蕩器等構成，其(qi)工作原理是先通過高頻PWM（脈寬調制(zhi)）開關電(dian)(dian)(dian)(dian)源技術，將汽車(che)電(dian)(dian)(dian)(dian)瓶所提供的12V直流(liu)電(dian)(dian)(dian)(dian)轉(zhuan)換成30kHz-50kHz、220V左(zuo)右的交(jiao)流(liu)電(dian)(dian)(dian)(dian)。然(ran)后再利(li)用橋(qiao)式(shi)整流(liu)、濾波、脈寬調制(zhi)及(ji)開關功率(lv)輸出等技術，將30kHz-50kHz、220V左(zuo)右的交(jiao)流(liu)電(dian)(dian)(dian)(dian)轉(zhuan)換成50Hz、220V的交(jiao)流(liu)電(dian)(dian)(dian)(dian)。
