在(zai)AI電(dian)(dian)(dian)(dian)(dian)路中,電(dian)(dian)(dian)(dian)(dian)感和(he)電(dian)(dian)(dian)(dian)(dian)容(rong)的(de)(de)協同工作(zuo)主要(yao)體現在(zai)濾(lv)波和(he)儲能方面。電(dian)(dian)(dian)(dian)(dian)容(rong)通過其(qi)充電(dian)(dian)(dian)(dian)(dian)和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)特性(xing),能夠平滑電(dian)(dian)(dian)(dian)(dian)壓波動,確保電(dian)(dian)(dian)(dian)(dian)壓的(de)(de)平穩(wen)性(xing),這在(zai)整流電(dian)(dian)(dian)(dian)(dian)路中尤為重(zhong)要(yao)。電(dian)(dian)(dian)(dian)(dian)感則通過其(qi)磁(ci)場效應(ying),能夠阻止電(dian)(dian)(dian)(dian)(dian)流的(de)(de)快(kuai)速變化,從而(er)在(zai)交流電(dian)(dian)(dian)(dian)(dian)場合中起到濾(lv)波作(zuo)用。
在低(di)通濾波器(qi)的設計中,電感和(he)電容的組合(he)可以(yi)有效(xiao)地濾除高頻(pin)噪聲(sheng),保留(liu)低(di)頻(pin)信號。然而(er),這(zhe)種(zhong)組合(he)也可能(neng)產(chan)生自(zi)激現象,因為電感和(he)電容都(dou)是儲能(neng)器(qi)件(jian)。為了避免自(zi)激,可以(yi)引入磁珠,它作(zuo)為耗能(neng)器(qi)件(jian),能(neng)夠(gou)與(yu)電容協同工(gong)作(zuo)而(er)不產(chan)生自(zi)激。
此(ci)外(wai),電(dian)(dian)容(rong)的(de)真實行為(wei)受到其寄生(sheng)電(dian)(dian)阻(ESR)和寄生(sheng)電(dian)(dian)感(ESL)的(de)影響,因(yin)此(ci)在選擇電(dian)(dian)容(rong)器(qi)時,需要(yao)確保(bao)其盡可能(neng)接近理想電(dian)(dian)容(rong)器(qi)的(de)行為(wei)。電(dian)(dian)感在直流供電(dian)(dian)的(de)電(dian)(dian)路(lu)板中(zhong)應(ying)用較(jiao)少,主要(yao)是因(yin)為(wei)其主要(yao)應(ying)用于交(jiao)流電(dian)(dian)場合。
電感和電容在AI電路(lu)中的(de)協同(tong)工作主要通過(guo)濾波(bo)和儲能來實現(xian),但(dan)需要注(zhu)意避免自激現(xian)象的(de)發生。
