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(kuang)，正常使用(yong)車(che)(che)載(zai)逆(ni)變器(qi)(qi)對(dui)汽車(che)(che)是沒(mei)(mei)有(you)損(sun)害(hai)的(de)(de)，不(bu)(bu)過(guo)如(ru)果使用(yong)不(bu)(bu)當的(de)(de)話(hua)，可(ke)能會對(dui)汽車(che)(che)電(dian)(dian)(dian)(dian)(dian)(dian)瓶造(zao)成(cheng)(cheng)一(yi)定(ding)的(de)(de)傷害(hai)：1、比如(ru)在(zai)車(che)(che)輛(liang)停車(che)(che)之后使用(yong)車(che)(che)載(zai)逆(ni)變器(qi)(qi)為車(che)(che)載(zai)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)，如(ru)果沒(mei)(mei)有(you)啟動(dong)(dong)(dong)發動(dong)(dong)(dong)機，會造(zao)成(cheng)(cheng)汽車(che)(che)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)虧電(dian)(dian)(dian)(dian)(dian)(dian)，從而對(dui)汽車(che)(che)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)造(zao)成(cheng)(cheng)損(sun)害(hai)。2、另外，市場上(shang)存(cun)在(zai)一(yi)些(xie)“小作坊”式(shi)的(de)(de)生產廠家，這些(xie)小廠家為了降低生產成(cheng)(cheng)本，節約了很多(duo)關(guan)鍵(jian)的(de)(de)器(qi)(qi)件，如(ru)過(guo)載(zai)保(bao)護(hu)、欠(qian)壓(ya)保(bao)護(hu)、過(guo)流(liu)保(bao)護(hu)、高壓(ya)保(bao)護(hu)以(yi)及高溫保(bao)護(hu)等，這種劣質(zhi)車(che)(che)載(zai)逆(ni)變器(qi)(qi)可(ke)能會對(dui)汽車(che)(che)造(zao)成(cheng)(cheng)傷害(hai)。3、還有(you)就(jiu)是，如(ru)果逆(ni)變器(qi)(qi)的(de)(de)啟動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)大于電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)CCA，那么電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)就(jiu)會“無法保(bao)持(chi)”，在(zai)啟動(dong)(dong)(dong)的(de)(de)瞬間就(jiu)會大幅度下降。這個時刻對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)健(jian)康(kang)極為不(bu)(bu)利，如(ru)果經常執行此(ci)循環，則(ze)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)壽命將受到顯著(zhu)影響。

三、車載逆變器可以用多大功率的電器

車(che)(che)載逆(ni)(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)可以(yi)(yi)用多(duo)大(da)(da)(da)功率的(de)(de)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)，要(yao)看車(che)(che)載逆(ni)(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)功率多(duo)大(da)(da)(da)，小型電(dian)(dian)(dian)源車(che)(che)載逆(ni)(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)通常(chang)(chang)輸出20~150瓦(wa)左右的(de)(de)功率，通常(chang)(chang)足以(yi)(yi)為大(da)(da)(da)多(duo)數筆記本電(dian)(dian)(dian)腦、低功率游戲(xi)機、相機和無人機電(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)等(deng)充(chong)(chong)電(dian)(dian)(dian)。大(da)(da)(da)一(yi)點的(de)(de)車(che)(che)載逆(ni)(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)功率在300瓦(wa)~500瓦(wa)左右，可以(yi)(yi)為更(geng)大(da)(da)(da)、更(geng)強(qiang)大(da)(da)(da)的(de)(de)電(dian)(dian)(dian)子設(she)備充(chong)(chong)電(dian)(dian)(dian)，并且通常(chang)(chang)可以(yi)(yi)為您(nin)提(ti)(ti)供第二個(ge)(ge)交流(liu)電(dian)(dian)(dian)源插(cha)(cha)座，讓(rang)您(nin)同時插(cha)(cha)入兩個(ge)(ge)設(she)備。1000瓦(wa)的(de)(de)車(che)(che)載逆(ni)(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)足以(yi)(yi)運(yun)行咖啡機、攪拌機或小型微波(bo)爐。三(san)四千瓦(wa)的(de)(de)車(che)(che)載逆(ni)(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)通常(chang)(chang)提(ti)(ti)供兩到四個(ge)(ge)交流(liu)電(dian)(dian)(dian)源插(cha)(cha)座，足以(yi)(yi)運(yun)行多(duo)個(ge)(ge)小型電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)甚至(zhi)更(geng)大(da)(da)(da)的(de)(de)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)，例如烤箱、某些(xie)電(dian)(dian)(dian)動工具和鋸(ju)子或帶有多(duo)個(ge)(ge)顯示(shi)器(qi)(qi)(qi)(qi)(qi)的(de)(de)強(qiang)大(da)(da)(da)游戲(xi) PC，這種大(da)(da)(da)功率車(che)(che)載逆(ni)(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)非常(chang)(chang)適合在路上花費大(da)(da)(da)量時間的(de)(de)房車(che)(che)、卡車(che)(che)和拖車(che)(che)。

四、車載逆變器功率怎么選

車載逆變(bian)(bian)器(qi)的(de)(de)(de)功(gong)率(lv)(lv)大(da)(da)小應(ying)該根(gen)據(ju)實際需(xu)(xu)(xu)要來選擇。通(tong)常情況下，我們(men)可以(yi)通(tong)過(guo)以(yi)下簡單的(de)(de)(de)公式計算：所需(xu)(xu)(xu)功(gong)率(lv)(lv)=使(shi)用(yong)設(she)備最大(da)(da)功(gong)率(lv)(lv)×系數，其中系數有兩個：1.5和2：系數1.5適用(yong)于阻性(xing)負載，如(ru)電(dian)(dian)(dian)(dian)熱毯、電(dian)(dian)(dian)(dian)暖氣、電(dian)(dian)(dian)(dian)爐等；系數2適用(yong)于感性(xing)負載，如(ru)液(ye)晶電(dian)(dian)(dian)(dian)視機、電(dian)(dian)(dian)(dian)冰(bing)箱(xiang)、電(dian)(dian)(dian)(dian)腦(nao)等。例如(ru)，如(ru)果你想(xiang)用(yong)車載逆變(bian)(bian)器(qi)驅動一臺功(gong)率(lv)(lv)為800W的(de)(de)(de)電(dian)(dian)(dian)(dian)視機，那(nei)么需(xu)(xu)(xu)要選擇的(de)(de)(de)逆變(bian)(bian)器(qi)功(gong)率(lv)(lv)應(ying)該為：所需(xu)(xu)(xu)功(gong)率(lv)(lv)=800W×2=1600W，因為還需(xu)(xu)(xu)要使(shi)用(yong)其他電(dian)(dian)(dian)(dian)器(qi)，以(yi)及(ji)考慮(lv)一些(xie)冗余，因此至(zhi)少要2000W的(de)(de)(de)車載逆變(bian)(bian)器(qi)。在(zai)選擇逆變(bian)(bian)器(qi)功(gong)率(lv)(lv)時，首先要考慮(lv)用(yong)途，如(ru)果只是(shi)為了充(chong)電(dian)(dian)(dian)(dian)或使(shi)用(yong)小功(gong)率(lv)(lv)設(she)備，那(nei)么功(gong)率(lv)(lv)較小的(de)(de)(de)逆變(bian)(bian)器(qi)就(jiu)可以(yi)滿足(zu)需(xu)(xu)(xu)求；如(ru)果想(xiang)要使(shi)用(yong)電(dian)(dian)(dian)(dian)視機、空調等功(gong)率(lv)(lv)較大(da)(da)的(de)(de)(de)設(she)備，就(jiu)需(xu)(xu)(xu)要選擇功(gong)率(lv)(lv)大(da)(da)的(de)(de)(de)車載逆變(bian)(bian)器(qi)。

五、車載逆變器的工作原理是什么

一般的(de)車載逆變(bian)器主要由(you)逆變(bian)橋(qiao)、濾(lv)波電(dian)路(lu)(lu)、控制電(dian)路(lu)(lu)、振(zhen)蕩器等(deng)構成，其工作原理(li)是(shi)先通過高頻PWM（脈寬調(diao)制）開關(guan)電(dian)源(yuan)技術，將汽車電(dian)瓶(ping)所提供的(de)12V直流電(dian)轉(zhuan)換成30kHz-50kHz、220V左右(you)(you)的(de)交流電(dian)。然(ran)后再利用橋(qiao)式整流、濾(lv)波、脈寬調(diao)制及開關(guan)功率輸(shu)出等(deng)技術，將30kHz-50kHz、220V左右(you)(you)的(de)交流電(dian)轉(zhuan)換成50Hz、220V的(de)交流電(dian)。
