升壓變壓器的原理是將低交流電壓
、大電流和小阻抗轉化為高交流電壓、小(xiao)電(dian)流(liu)和(he)大(da)阻(zu)抗(kang)。當(dang)主(zhu)線(xian)圈(quan)中(zhong)有(you)交(jiao)流(liu)電(dian)時(shi)，交(jiao)流(liu)磁(ci)通(tong)會(hui)在(zai)鐵(tie)芯(xin)中(zhong)產(chan)生(sheng)，從(cong)而(er)在(zai)次(ci)線(xian)圈(quan)中(zhong)感(gan)知(zhi)電(dian)壓(ya)。如(ru)果(guo)使(shi)用(yong)電(dian)池(chi)，因(yin)為(wei)它(ta)是(shi)直(zhi)流(liu)的(de)，需(xu)要(yao)在(zai)輸(shu)入(ru)電(dian)路(lu)中(zhong)添(tian)加(jia)開(kai)關(guan)電(dian)路(lu)，並(bing)將(jiang)其(qi)轉(zhuan)換(huan)為(wei)不(bu)斷(duan)變(bian)化(hua)的(de)電(dian)壓(ya)。隻(zhi)有(you)這(zhe)樣(yang)，才(cai)能(neng)在(zai)輸(shu)出(chu)端(duan)獲(huo)得(de)交(jiao)變(bian)的(de)高(gao)電(dian)壓(ya)。
