電(dian)磁爐(lu)都有(you)三大電(dian)容，大概為 5UF，引線(xian)電(dian)容器(qi)，2UF，引線(xian)電(dian)容器(qi)無(wu)耳，0.27UF，這三個電(dian)容對(dui)電(dian)磁爐(lu)的(de)正常工作(zuo)起(qi)至關重要的(de)作(zuo)用

1:抗(kang)干擾(rao)(rao)電(dian)(dian)(dian)(dian)容(rong)。該電(dian)(dian)(dian)(dian)容(rong)的作用是防止電(dian)(dian)(dian)(dian)磁(ci)爐工作時(shi)產生的高頻干擾(rao)(rao)串入市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)網，影(ying)響其它(ta)電(dian)(dian)(dian)(dian)器。該電(dian)(dian)(dian)(dian)容(rong)一般為 2uf，是跨(kua)接在市電(dian)(dian)(dian)(dian)220V之間的，耐壓275V。

2:濾波電(dian)容，該電(dian)容的作用(yong)是把整流(liu)后的脈動直流(liu)電(dian)變成(cheng)平滑的直流(liu)電(dian)壓(ya)。它是直接(jie)接(jie)在(zai)全橋整流(liu)之后，一般(ban) 4uf--5uf。一般(ban)該電(dian)容選用(yong)MKPX2電(dian)容，規格為275V/AC，400V/DC

3:諧振電(dian)容，它(ta)的(de)(de)(de)作用是(shi)與并(bing)聯的(de)(de)(de)加熱(re)線圈(quan)諧振產(chan)生高頻(pin)的(de)(de)(de)交變(bian)電(dian)流(liu)，通常為 0.27---0.4uf，耐壓(ya)一般在800V到1200V之間該電(dian)容變(bian)小會使電(dian)磁(ci)爐(lu)功率變(bian)小，即加熱(re)很(hen)慢的(de)(de)(de)故(gu)障。

光伏儲(chu)能(neng)(neng)(neng)系(xi)統(tong)的(de)(de)功能(neng)(neng)(neng)是將(jiang)太陽能(neng)(neng)(neng)轉化為電能(neng)(neng)(neng)，并將(jiang)電能(neng)(neng)(neng)儲(chu)存起(qi)來(lai)，以(yi)(yi)便在需(xu)要時(shi)供(gong)電使用。光伏儲(chu)能(neng)(neng)(neng)系(xi)統(tong)一般由光伏電池組、逆變(bian)器電池組和電容等組成(cheng)。其中，電容作(zuo)為儲(chu)能(neng)(neng)(neng)系(xi)統(tong)的(de)(de)重要組件，具(ju)有以(yi)(yi)下(xia)幾個方(fang)面(mian)的(de)(de)作(zuo)用:

平(ping)滑電(dian)(dian)(dian)壓波(bo)動(dong):光伏(fu)儲能(neng)(neng)(neng)(neng)系(xi)統(tong)的(de)(de)(de)電(dian)(dian)(dian)容可以(yi)(yi)平(ping)滑電(dian)(dian)(dian)壓波(bo)動(dong)，使(shi)得系(xi)統(tong)能(neng)(neng)(neng)(neng)夠穩定地輸出電(dian)(dian)(dian)能(neng)(neng)(neng)(neng)。光伏(fu)發電(dian)(dian)(dian)系(xi)統(tong)的(de)(de)(de)輸出電(dian)(dian)(dian)壓存在一定的(de)(de)(de)波(bo)動(dong)性，特(te)別是在天氣變(bian)化(hua)(hua)較大的(de)(de)(de)情況下。通過使(shi)用電(dian)(dian)(dian)容，可以(yi)(yi)減小電(dian)(dian)(dian)壓波(bo)動(dong)，保(bao)證儲能(neng)(neng)(neng)(neng)系(xi)統(tong)的(de)(de)(de)穩定供電(dian)(dian)(dian)。緩沖(chong)電(dian)(dian)(dian)能(neng)(neng)(neng)(neng)流:光伏(fu)儲能(neng)(neng)(neng)(neng)系(xi)統(tong)的(de)(de)(de)電(dian)(dian)(dian)容可以(yi)(yi)起(qi)到緩沖(chong)電(dian)(dian)(dian)能(neng)(neng)(neng)(neng)流的(de)(de)(de)作用，使(shi)得系(xi)統(tong)能(neng)(neng)(neng)(neng)夠更(geng)好地適應負載的(de)(de)(de)變(bian)化(hua)(hua)。
