逆變器總成簡介

逆變(bian)器(qi)總(zong)成(cheng)逆變(bian)器(qi)作(zuo)用就是把直流電變(bian)換為交流電，逆變(bian)器(qi)主流有2種連接方式(shi)：

1、直(zhi)接連在汽車電瓶上(shang)，功(gong)率較(jiao)高，可以(yi)為(wei)更(geng)多(duo)大(da)功(gong)率用(yong)電器使用(yong)，缺點是風險比較(jiao)大(da)；

2、通過點煙器(qi)(qi)(qi)電(dian)源轉換，輸(shu)出(chu)功(gong)(gong)率(lv)比(bi)(bi)較小(xiao)，但也(ye)足(zu)夠大多數(shu)小(xiao)型電(dian)器(qi)(qi)(qi)使用(yong)。逆變(bian)(bian)器(qi)(qi)(qi)是把直流電(dian)能（電(dian)池(chi)、蓄電(dian)瓶）轉變(bian)(bian)成交流電(dian)（一(yi)般為220V，50Hz正弦波），其由逆變(bian)(bian)橋(qiao)、控制邏輯(ji)和濾波電(dian)路組成。逆變(bian)(bian)器(qi)(qi)(qi)在工(gong)作時其本身也(ye)要(yao)消(xiao)耗一(yi)部分(fen)電(dian)力，因(yin)此輸(shu)入(ru)功(gong)(gong)率(lv)要(yao)大于其輸(shu)出(chu)功(gong)(gong)率(lv)。逆變(bian)(bian)器(qi)(qi)(qi)的效率(lv)即(ji)是逆變(bian)(bian)器(qi)(qi)(qi)輸(shu)出(chu)功(gong)(gong)率(lv)與(yu)輸(shu)入(ru)功(gong)(gong)率(lv)之比(bi)(bi)，即(ji)逆變(bian)(bian)器(qi)(qi)(qi)效率(lv)為輸(shu)出(chu)功(gong)(gong)率(lv)比(bi)(bi)上輸(shu)入(ru)功(gong)(gong)率(lv)。
