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

一般情(qing)況，正常(chang)使用(yong)車(che)(che)載(zai)逆(ni)變器(qi)(qi)對(dui)(dui)汽(qi)(qi)車(che)(che)是沒有損害(hai)(hai)的(de)，不(bu)過如果使用(yong)不(bu)當的(de)話，可能會對(dui)(dui)汽(qi)(qi)車(che)(che)電(dian)(dian)(dian)(dian)瓶造(zao)成(cheng)一定的(de)傷害(hai)(hai)：1、比如在車(che)(che)輛停車(che)(che)之后使用(yong)車(che)(che)載(zai)逆(ni)變器(qi)(qi)為(wei)車(che)(che)載(zai)電(dian)(dian)(dian)(dian)器(qi)(qi)供電(dian)(dian)(dian)(dian)，如果沒有啟動(dong)(dong)發動(dong)(dong)機，會造(zao)成(cheng)汽(qi)(qi)車(che)(che)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)虧(kui)電(dian)(dian)(dian)(dian)，從而對(dui)(dui)汽(qi)(qi)車(che)(che)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)造(zao)成(cheng)損害(hai)(hai)。2、另外(wai)，市(shi)場上存在一些(xie)“小作(zuo)坊”式(shi)的(de)生產廠家(jia)，這(zhe)些(xie)小廠家(jia)為(wei)了降(jiang)低(di)生產成(cheng)本，節約了很多關鍵的(de)器(qi)(qi)件，如過載(zai)保(bao)護(hu)、欠壓保(bao)護(hu)、過流保(bao)護(hu)、高(gao)壓保(bao)護(hu)以及高(gao)溫保(bao)護(hu)等，這(zhe)種劣質(zhi)車(che)(che)載(zai)逆(ni)變器(qi)(qi)可能會對(dui)(dui)汽(qi)(qi)車(che)(che)造(zao)成(cheng)傷害(hai)(hai)。3、還(huan)有就(jiu)是，如果逆(ni)變器(qi)(qi)的(de)啟動(dong)(dong)電(dian)(dian)(dian)(dian)流大于電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)CCA，那么電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)(dian)壓就(jiu)會“無法保(bao)持”，在啟動(dong)(dong)的(de)瞬間就(jiu)會大幅度下降(jiang)。這(zhe)個時刻對(dui)(dui)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)健康極為(wei)不(bu)利，如果經常(chang)執行此循環，則電(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)(che)載(zai)逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)可以(yi)(yi)用多大(da)功(gong)(gong)率(lv)的(de)電器(qi)(qi)(qi)，要看(kan)車(che)(che)(che)載(zai)逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)的(de)功(gong)(gong)率(lv)多大(da)，小(xiao)型電源(yuan)車(che)(che)(che)載(zai)逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)通(tong)常輸出20~150瓦(wa)(wa)(wa)左右的(de)功(gong)(gong)率(lv)，通(tong)常足以(yi)(yi)為大(da)多數筆記本電腦(nao)、低功(gong)(gong)率(lv)游(you)戲機、相機和(he)無人(ren)機電池充電器(qi)(qi)(qi)等充電。大(da)一點的(de)車(che)(che)(che)載(zai)逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)功(gong)(gong)率(lv)在(zai)300瓦(wa)(wa)(wa)~500瓦(wa)(wa)(wa)左右，可以(yi)(yi)為更大(da)、更強大(da)的(de)電子(zi)(zi)設(she)備(bei)充電，并且(qie)通(tong)常可以(yi)(yi)為您提(ti)供第二個(ge)交(jiao)(jiao)流(liu)電源(yuan)插座(zuo)，讓您同時插入兩(liang)個(ge)設(she)備(bei)。1000瓦(wa)(wa)(wa)的(de)車(che)(che)(che)載(zai)逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)足以(yi)(yi)運(yun)行咖啡(fei)機、攪(jiao)拌機或(huo)(huo)小(xiao)型微波爐。三四千瓦(wa)(wa)(wa)的(de)車(che)(che)(che)載(zai)逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)通(tong)常提(ti)供兩(liang)到四個(ge)交(jiao)(jiao)流(liu)電源(yuan)插座(zuo)，足以(yi)(yi)運(yun)行多個(ge)小(xiao)型電器(qi)(qi)(qi)甚至(zhi)更大(da)的(de)電器(qi)(qi)(qi)，例如烤箱、某些電動(dong)工具(ju)和(he)鋸子(zi)(zi)或(huo)(huo)帶(dai)有多個(ge)顯示器(qi)(qi)(qi)的(de)強大(da)游(you)戲 PC，這種大(da)功(gong)(gong)率(lv)車(che)(che)(che)載(zai)逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)非常適合在(zai)路上花費(fei)大(da)量時間的(de)房(fang)車(che)(che)(che)、卡車(che)(che)(che)和(he)拖車(che)(che)(che)。

四、車載逆變器功率怎么選

車載逆變(bian)(bian)(bian)(bian)器(qi)的(de)(de)(de)(de)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)大(da)小(xiao)應該根據實際需(xu)要(yao)來選擇。通常情(qing)況下，我(wo)們可以通過以下簡單的(de)(de)(de)(de)公式(shi)計(ji)算：所需(xu)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)=使(shi)用(yong)(yong)(yong)設(she)備最(zui)大(da)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)×系(xi)數(shu)，其(qi)(qi)中系(xi)數(shu)有兩(liang)個：1.5和2：系(xi)數(shu)1.5適用(yong)(yong)(yong)于(yu)阻性負載，如電(dian)(dian)(dian)熱(re)毯(tan)、電(dian)(dian)(dian)暖(nuan)氣(qi)、電(dian)(dian)(dian)爐等；系(xi)數(shu)2適用(yong)(yong)(yong)于(yu)感性負載，如液晶電(dian)(dian)(dian)視(shi)機、電(dian)(dian)(dian)冰箱、電(dian)(dian)(dian)腦等。例如，如果你(ni)想(xiang)用(yong)(yong)(yong)車載逆變(bian)(bian)(bian)(bian)器(qi)驅(qu)動一臺(tai)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)為800W的(de)(de)(de)(de)電(dian)(dian)(dian)視(shi)機，那么需(xu)要(yao)選擇的(de)(de)(de)(de)逆變(bian)(bian)(bian)(bian)器(qi)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)應該為：所需(xu)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)=800W×2=1600W，因為還需(xu)要(yao)使(shi)用(yong)(yong)(yong)其(qi)(qi)他電(dian)(dian)(dian)器(qi)，以及考(kao)(kao)慮一些冗余，因此至少要(yao)2000W的(de)(de)(de)(de)車載逆變(bian)(bian)(bian)(bian)器(qi)。在選擇逆變(bian)(bian)(bian)(bian)器(qi)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)時，首先(xian)要(yao)考(kao)(kao)慮用(yong)(yong)(yong)途(tu)，如果只(zhi)是為了充電(dian)(dian)(dian)或使(shi)用(yong)(yong)(yong)小(xiao)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)設(she)備，那么功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)較(jiao)小(xiao)的(de)(de)(de)(de)逆變(bian)(bian)(bian)(bian)器(qi)就可以滿(man)足需(xu)求；如果想(xiang)要(yao)使(shi)用(yong)(yong)(yong)電(dian)(dian)(dian)視(shi)機、空(kong)調等功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)較(jiao)大(da)的(de)(de)(de)(de)設(she)備，就需(xu)要(yao)選擇功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)大(da)的(de)(de)(de)(de)車載逆變(bian)(bian)(bian)(bian)器(qi)。

五、車載逆變器的工作原理是什么

一般的(de)車載逆變器主要由逆變橋、濾(lv)波電(dian)(dian)路、控制電(dian)(dian)路、振蕩(dang)器等構成(cheng)，其(qi)工作原理是先通過(guo)高頻PWM（脈(mo)寬(kuan)調制）開(kai)關(guan)電(dian)(dian)源技(ji)術(shu)，將(jiang)汽(qi)車電(dian)(dian)瓶所提(ti)供的(de)12V直流(liu)電(dian)(dian)轉換成(cheng)30kHz-50kHz、220V左(zuo)右(you)(you)的(de)交流(liu)電(dian)(dian)。然后再利用橋式整(zheng)流(liu)、濾(lv)波、脈(mo)寬(kuan)調制及開(kai)關(guan)功率輸(shu)出等技(ji)術(shu)，將(jiang)30kHz-50kHz、220V左(zuo)右(you)(you)的(de)交流(liu)電(dian)(dian)轉換成(cheng)50Hz、220V的(de)交流(liu)電(dian)(dian)。
