充電器在充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時如遇上(shang)劣質充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)會出現(xian)無(wu)故自燃，爆(bao)手(shou)機，甚(shen)至是在充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時觸(chu)電(dian)(dian)(dian)(dian)，引發人員(yuan)傷(shang)忙。這一切都源于(yu)(yu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)中(zhong)的電(dian)(dian)(dian)(dian)子(zi)元器(qi)(qi)(qi)(qi)件的品(pin)質問題。手(shou)機充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)y電(dian)(dian)(dian)(dian)容用(yong)于(yu)(yu)共模(mo)濾波(bo)，它(ta)接(jie)于(yu)(yu)L于(yu)(yu)地(di)(di)或N于(yu)(yu)地(di)(di)之間，濾除L對地(di)(di)或N對地(di)(di)的共模(mo)信號(hao)，y電(dian)(dian)(dian)(dian)容通常(chang)對稱使用(yong)，作用(yong)主要有旁(pang)路；去耦(ou)；濾波(bo)；儲能。

在入力初級端有個耐(nai)(nai)壓400v的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)，那是主濾波電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)，濾除市電(dian)(dian)(dian)(dian)(dian)(dian)整流后的(de)(de)(de)(de)(de)雜(za)波，使后面(mian)電(dian)(dian)(dian)(dian)(dian)(dian)路能(neng)得到更(geng)為平穩(wen)(wen)的(de)(de)(de)(de)(de)直流正弦波，只有雜(za)波越少(shao)，電(dian)(dian)(dian)(dian)(dian)(dian)路才能(neng)更(geng)好(hao)的(de)(de)(de)(de)(de)穩(wen)(wen)定工作(zuo)(zuo)，至(zhi)于電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)選(xuan)400v耐(nai)(nai)壓值(zhi)，開關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)路工作(zuo)(zuo)后，其電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)兩(liang)端將有300多伏壓降，再加(jia)上通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)瞬(shun)間峰值(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)壓，所(suo)以如果耐(nai)(nai)壓值(zhi)太(tai)小，會(hui)影起電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)暴裂，而輸出(chu)端電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)視其輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓大(da)(da)小選(xuan)擇適合的(de)(de)(de)(de)(de)耐(nai)(nai)壓值(zhi)，如5v則耐(nai)(nai)壓值(zhi)是10v，該(gai)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)也是濾波作(zuo)(zuo)用(yong)，使充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)輸出(chu)平穩(wen)(wen)的(de)(de)(de)(de)(de)直流電(dian)(dian)(dian)(dian)(dian)(dian)，至(zhi)于容(rong)(rong)(rong)(rong)量(liang)的(de)(de)(de)(de)(de)大(da)(da)小，前面(mian)耐(nai)(nai)壓大(da)(da)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)一般選(xuan)擇47~470uF，輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)一般100~1000uF，原則上是容(rong)(rong)(rong)(rong)量(liang)越大(da)(da)越好(hao)，但實際(ji)上容(rong)(rong)(rong)(rong)量(liang)越大(da)(da)漏電(dian)(dian)(dian)(dian)(dian)(dian)流越大(da)(da)，y電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)通(tong)交流阻(zu)直流。所(suo)以我們(men)為手機(ji)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時要選(xuan)擇質量(liang)好(hao)的(de)(de)(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。而y電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)的(de)(de)(de)(de)(de)品質好(hao)壞直接充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)(de)(de)質量(liang)。
作為手機充電器中的(de)y電容，質量保(bao)障是很重要(yao)的(de)，選購y電容時選擇(ze)必須有安(an)全(quan)檢測機構的(de)認證(zheng)和各(ge)工業國的(de)安(an)規認證(zheng)，一般產(chan)品(pin)上都(dou)有認證(zheng)標識。

　　手(shou)機充電(dian)(dian)(dian)器(qi)y電(dian)(dian)(dian)容(rong)(rong)用于共(gong)模濾波(bo)，原則上是容(rong)(rong)量越大越好.但實際(ji)上容(rong)(rong)量越大漏電(dian)(dian)(dian)流(liu)(liu)越大，y電(dian)(dian)(dian)容(rong)(rong)通交流(liu)(liu)阻直(zhi)流(liu)(liu).所以我們為手(shou)機充電(dian)(dian)(dian)時要選擇質(zhi)(zhi)量好的(de)充電(dian)(dian)(dian)器(qi)，而(er)y電(dian)(dian)(dian)容(rong)(rong)的(de)品質(zhi)(zhi)好壞直(zhi)接(jie)充電(dian)(dian)(dian)器(qi)的(de)質(zhi)(zhi)量.
