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(ban)情況,正(zheng)常使(shi)用車載逆(ni)變(bian)器(qi)(qi)對(dui)汽車是沒有(you)損害的(de),不(bu)(bu)過如(ru)果(guo)使(shi)用不(bu)(bu)當的(de)話,可能會(hui)對(dui)汽車電(dian)(dian)(dian)(dian)瓶造成一定的(de)傷害:1、比如(ru)在(zai)車輛停車之后使(shi)用車載逆(ni)變(bian)器(qi)(qi)為車載電(dian)(dian)(dian)(dian)器(qi)(qi)供(gong)電(dian)(dian)(dian)(dian),如(ru)果(guo)沒有(you)啟動(dong)(dong)發動(dong)(dong)機,會(hui)造成汽車蓄(xu)電(dian)(dian)(dian)(dian)池的(de)虧電(dian)(dian)(dian)(dian),從而(er)對(dui)汽車蓄(xu)電(dian)(dian)(dian)(dian)池造成損害。2、另外,市場上存(cun)在(zai)一些“小(xiao)作坊(fang)”式(shi)的(de)生產(chan)廠(chang)(chang)家,這些小(xiao)廠(chang)(chang)家為了降(jiang)低(di)生產(chan)成本,節約了很多關鍵的(de)器(qi)(qi)件,如(ru)過載保(bao)(bao)護(hu)、欠壓保(bao)(bao)護(hu)、過流保(bao)(bao)護(hu)、高(gao)(gao)壓保(bao)(bao)護(hu)以及高(gao)(gao)溫保(bao)(bao)護(hu)等,這種劣質(zhi)車載逆(ni)變(bian)器(qi)(qi)可能會(hui)對(dui)汽車造成傷害。3、還有(you)就(jiu)(jiu)是,如(ru)果(guo)逆(ni)變(bian)器(qi)(qi)的(de)啟動(dong)(dong)電(dian)(dian)(dian)(dian)流大于電(dian)(dian)(dian)(dian)池的(de)CCA,那么電(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)壓就(jiu)(jiu)會(hui)“無法保(bao)(bao)持”,在(zai)啟動(dong)(dong)的(de)瞬間就(jiu)(jiu)會(hui)大幅度下降(jiang)。這個時刻(ke)對(dui)電(dian)(dian)(dian)(dian)池的(de)健康極為不(bu)(bu)利,如(ru)果(guo)經常執行此(ci)循(xun)環,則電(dian)(dian)(dian)(dian)池壽命將受(shou)到顯著影響。
三、車載逆變器可以用多大功率的電器
車(che)(che)(che)(che)載(zai)(zai)逆(ni)變(bian)器可以(yi)(yi)(yi)(yi)用多(duo)大(da)(da)功(gong)(gong)率(lv)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)器,要看車(che)(che)(che)(che)載(zai)(zai)逆(ni)變(bian)器的(de)(de)(de)(de)(de)功(gong)(gong)率(lv)多(duo)大(da)(da),小(xiao)型電(dian)(dian)(dian)源車(che)(che)(che)(che)載(zai)(zai)逆(ni)變(bian)器通(tong)常(chang)(chang)輸出(chu)20~150瓦(wa)左右的(de)(de)(de)(de)(de)功(gong)(gong)率(lv),通(tong)常(chang)(chang)足(zu)以(yi)(yi)(yi)(yi)為大(da)(da)多(duo)數筆(bi)記本電(dian)(dian)(dian)腦、低(di)功(gong)(gong)率(lv)游戲(xi)機(ji)、相機(ji)和(he)(he)無人機(ji)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器等(deng)充(chong)電(dian)(dian)(dian)。大(da)(da)一點的(de)(de)(de)(de)(de)車(che)(che)(che)(che)載(zai)(zai)逆(ni)變(bian)器功(gong)(gong)率(lv)在300瓦(wa)~500瓦(wa)左右,可以(yi)(yi)(yi)(yi)為更大(da)(da)、更強大(da)(da)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)設備充(chong)電(dian)(dian)(dian),并(bing)且通(tong)常(chang)(chang)可以(yi)(yi)(yi)(yi)為您(nin)提供(gong)第(di)二(er)個交流電(dian)(dian)(dian)源插座,讓您(nin)同時插入兩個設備。1000瓦(wa)的(de)(de)(de)(de)(de)車(che)(che)(che)(che)載(zai)(zai)逆(ni)變(bian)器足(zu)以(yi)(yi)(yi)(yi)運行咖啡(fei)機(ji)、攪拌(ban)機(ji)或小(xiao)型微波爐。三(san)四千瓦(wa)的(de)(de)(de)(de)(de)車(che)(che)(che)(che)載(zai)(zai)逆(ni)變(bian)器通(tong)常(chang)(chang)提供(gong)兩到(dao)四個交流電(dian)(dian)(dian)源插座,足(zu)以(yi)(yi)(yi)(yi)運行多(duo)個小(xiao)型電(dian)(dian)(dian)器甚至更大(da)(da)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)器,例如烤(kao)箱、某(mou)些(xie)電(dian)(dian)(dian)動工具和(he)(he)鋸子(zi)或帶有多(duo)個顯示器的(de)(de)(de)(de)(de)強大(da)(da)游戲(xi) PC,這(zhe)種(zhong)大(da)(da)功(gong)(gong)率(lv)車(che)(che)(che)(che)載(zai)(zai)逆(ni)變(bian)器非常(chang)(chang)適合在路(lu)上(shang)花費大(da)(da)量時間(jian)的(de)(de)(de)(de)(de)房車(che)(che)(che)(che)、卡車(che)(che)(che)(che)和(he)(he)拖車(che)(che)(che)(che)。
四、車載逆變器功率怎么選
車載(zai)逆(ni)(ni)變(bian)器(qi)的(de)功(gong)(gong)(gong)率大小(xiao)應(ying)該(gai)根據實際需(xu)要(yao)來選擇(ze)。通常情況下,我們可以(yi)通過以(yi)下簡單的(de)公式計算(suan):所(suo)需(xu)功(gong)(gong)(gong)率=使(shi)用(yong)(yong)(yong)設備最大功(gong)(gong)(gong)率×系數(shu),其(qi)中(zhong)系數(shu)有(you)兩個:1.5和2:系數(shu)1.5適(shi)用(yong)(yong)(yong)于阻性負載(zai),如(ru)(ru)電(dian)熱(re)毯、電(dian)暖氣、電(dian)爐等(deng);系數(shu)2適(shi)用(yong)(yong)(yong)于感性負載(zai),如(ru)(ru)液晶(jing)電(dian)視機、電(dian)冰箱、電(dian)腦等(deng)。例如(ru)(ru),如(ru)(ru)果你想(xiang)用(yong)(yong)(yong)車載(zai)逆(ni)(ni)變(bian)器(qi)驅動一(yi)臺功(gong)(gong)(gong)率為800W的(de)電(dian)視機,那么(me)需(xu)要(yao)選擇(ze)的(de)逆(ni)(ni)變(bian)器(qi)功(gong)(gong)(gong)率應(ying)該(gai)為:所(suo)需(xu)功(gong)(gong)(gong)率=800W×2=1600W,因為還需(xu)要(yao)使(shi)用(yong)(yong)(yong)其(qi)他電(dian)器(qi),以(yi)及(ji)考(kao)慮(lv)一(yi)些冗余,因此至少(shao)要(yao)2000W的(de)車載(zai)逆(ni)(ni)變(bian)器(qi)。在選擇(ze)逆(ni)(ni)變(bian)器(qi)功(gong)(gong)(gong)率時,首先要(yao)考(kao)慮(lv)用(yong)(yong)(yong)途,如(ru)(ru)果只(zhi)是為了充電(dian)或使(shi)用(yong)(yong)(yong)小(xiao)功(gong)(gong)(gong)率設備,那么(me)功(gong)(gong)(gong)率較小(xiao)的(de)逆(ni)(ni)變(bian)器(qi)就可以(yi)滿足需(xu)求;如(ru)(ru)果想(xiang)要(yao)使(shi)用(yong)(yong)(yong)電(dian)視機、空(kong)調(diao)等(deng)功(gong)(gong)(gong)率較大的(de)設備,就需(xu)要(yao)選擇(ze)功(gong)(gong)(gong)率大的(de)車載(zai)逆(ni)(ni)變(bian)器(qi)。
五、車載逆變器的工作原理是什么
一般的車(che)載逆變(bian)器(qi)主要由逆變(bian)橋、濾波電路(lu)、控(kong)制(zhi)(zhi)電路(lu)、振蕩器(qi)等構成,其(qi)工(gong)作原(yuan)理(li)是先通過高頻(pin)PWM(脈寬調制(zhi)(zhi))開(kai)(kai)關電源(yuan)技術(shu),將汽車(che)電瓶所提供(gong)的12V直流電轉(zhuan)換成30kHz-50kHz、220V左(zuo)右(you)(you)的交流電。然后(hou)再利(li)用橋式整流、濾波、脈寬調制(zhi)(zhi)及(ji)開(kai)(kai)關功率輸出(chu)等技術(shu),將30kHz-50kHz、220V左(zuo)右(you)(you)的交流電轉(zhuan)換成50Hz、220V的交流電。
