整流變壓器廠家對整流(liu)變壓器的交流(liu)

1.交(jiao)流變(bian)交(jiao)流：如變(bian)電(dian)(dian)站里的交(jiao)流變(bian)壓(ya)器(qi)。變(bian)壓(ya)器(qi)有兩組線(xian)(xian)圈。初級(ji)線(xian)(xian)圈和次級(ji)線(xian)(xian)圈。次級(ji)線(xian)(xian)圈在初級(ji)線(xian)(xian)圈外(wai)邊。當初級(ji)線(xian)(xian)圈通(tong)上(shang)(shang)交(jiao)流電(dian)(dian)時，變(bian)壓(ya)器(qi)鐵芯產(chan)生交(jiao)變(bian)磁場，次級(ji)線(xian)(xian)圈就(jiu)產(chan)生感應電(dian)(dian)動勢。變(bian)壓(ya)器(qi)的線(xian)(xian)圈的匝(za)數比等于電(dian)(dian)壓(ya)比。例如：初級(ji)線(xian)(xian)圈是500匝(za)，次級(ji)線(xian)(xian)圈是250匝(za)，初級(ji)通(tong)上(shang)(shang)220V交(jiao)流電(dian)(dian)，次級(ji)電(dian)(dian)壓(ya)就(jiu)是110V。變(bian)壓(ya)器(qi)能降(jiang)壓(ya)也(ye)能升壓(ya)。

2、交(jiao)(jiao)流(liu)變直流(liu)：如手機(ji)的充電(dian)器其實還是(shi)交(jiao)(jiao)流(liu)變交(jiao)(jiao)流(liu)，電(dian)壓降低了，再通(tong)過濾波電(dian)路把(ba)交(jiao)(jiao)流(liu)電(dian)變成直流(liu)電(dian)。

3、直流變(bian)交流：如一(yi)些設(she)備(bei)(bei)的UPS備(bei)(bei)用電(dian)源首(shou)先要用電(dian)子元件將直流電(dian)變(bian)為交流電(dian)，然后(hou)用變(bian)壓(ya)器(qi)變(bian)換電(dian)壓(ya)。這個(ge)設(she)備(bei)(bei)叫逆變(bian)器(qi)。它由逆變(bian)橋、控制邏輯和濾波電(dian)路組成.
