濾波電(dian)容沖的電(dian)是直流還是交(jiao)流

在電(dian)(dian)子(zi)線路中，電(dian)(dian)容(rong)用(yong)來通(tong)過交(jiao)流而(er)阻隔直(zhi)流，也(ye)用(yong)來存儲和釋放(fang)(fang)電(dian)(dian)荷以充當濾波(bo)器，平滑(hua)輸出脈(mo)動信號。 電(dian)(dian)容(rong)是(shi)使用(yong)直(zhi)流進行(xing)充電(dian)(dian)的(de)(de)，放(fang)(fang)的(de)(de)也(ye)是(shi)直(zhi)流。 單相(xiang)電(dian)(dian)機上的(de)(de)電(dian)(dian)容(rong)就是(shi)利用(yong)電(dian)(dian)容(rong)能通(tong)過交(jiao)流電(dian)(dian)但改變了相(xiang)位角的(de)(de)原理。
