逆變器(qi)總成逆變器(qi)作用就是把直流電(dian)變換為交(jiao)流電(dian)，逆變器(qi)主流有2種連接(jie)方式：
1、直接連在(zai)汽(qi)車電(dian)(dian)瓶上，功率較(jiao)高，可以為更多大功率用電(dian)(dian)器使(shi)用，缺點是風險(xian)比較(jiao)大；
2、通過點(dian)煙器電(dian)(dian)源(yuan)轉換，輸(shu)(shu)出(chu)功率(lv)比較小，但也(ye)足(zu)夠(gou)大多數小型電(dian)(dian)器使用(yong)。逆變(bian)(bian)器是把直流電(dian)(dian)能(neng)（電(dian)(dian)池、蓄電(dian)(dian)瓶）轉變(bian)(bian)成(cheng)交流電(dian)(dian)（一般為(wei)220V，50Hz正弦(xian)波），其由(you)逆變(bian)(bian)橋、控制邏(luo)輯(ji)和濾波電(dian)(dian)路組成(cheng)。逆變(bian)(bian)器在工作時(shi)其本(ben)身也(ye)要消耗一部分電(dian)(dian)力，因此(ci)輸(shu)(shu)入(ru)功率(lv)要大于其輸(shu)(shu)出(chu)功率(lv)。逆變(bian)(bian)器的效(xiao)率(lv)即是逆變(bian)(bian)器輸(shu)(shu)出(chu)功率(lv)與輸(shu)(shu)入(ru)功率(lv)之比，即逆變(bian)(bian)器效(xiao)率(lv)為(wei)輸(shu)(shu)出(chu)功率(lv)比上輸(shu)(shu)入(ru)功率(lv)。
