Kokubili i-buck circuit kanye ne-boost circuit yiziyingi ezibalulekile ekwakhiweni kwehadiwe, ikakhulukazi kohlakaniphileAma-ONUkanye namadivayisi we-OLT.Umsebenzi we-VOICE kuI-ONUidizayini isebenzisa i-boost circuit ukuze ikhulise ngokuqondile amandla kagesi futhi inikeze amandla kumafoni angaphandle.Indlela engcono kakhulu yokuqonda i-boost circuit ukuqonda ngokugcwele i-voltage kanye namandla engxenye ngayinye yesekethe, Ukuhlangabezana nezinkinga ezithile kungakhomba ngokucacile iphuzu lenkinga.Isibonelo, kwenzekani lapho i-inductance ikhuphuka?Kwenzekani lapho i-capacitance ikhula?Uyini umthelela wemvamisa yokusebenza?Okulandelayo, inkampani yethu izokuchazela.
Okokuqala, ake sikhulume ngesimiso esiyisisekelo sokusebenza sesekethe ye-BOOST: Emfanekisweni ongezansi, i-MOS transistor iyiswishi.Inqobo nje uma ijubane lishesha ngokwanele (imvamisa yokushintsha iphezulu ngokwanele), isikhathi sokuvula nesokuvala (isikhathi sokushaja nokukhipha) silawulwa kahle, futhi kuhlanganiswe ne-capacitor yesihlungi okukhiphayo, i-Vo eqinile ingatholakala (izwi voltage yethu ehlakaniphileI-ONUngokuvamile ingu-48V), okuyi-voltage ephumayo.
Uma iswishi ivuliwe, i-inductor L iyamiswa, i-diode iyanqanyulwa, futhi i-Vi ishaja i-inductor L. I-voltage emaphethelweni womabili we-inductor ithi Vi (imvamisa i-12VI-ONUukunikezwa kwamandla kagesi).Lapho iswishi ingaqhubeki, ngenxa yokuthi i-inductor L isivele ishajiwe futhi kukhona okwamanje egelezayo kuyo, okwamanje emikhawulweni yomibili ye-inductor ayikwazi ukushintsha ngokuzumayo.Ngakho-ke, i-voltage izodonswa ukwenza i-diode ekuziphatheni okufanele.I-voltage ephumayo i-Vo ihlala njalo, futhi ukwehla kwe-voltage ye-diode conduction yi-Vd, ngakho-ke i-voltage ekugcineni kwe-inductor yi-Vo + Vd, futhi i-voltage ekugcineni kwesokunxele ye-inductor ifaka amandla Vi.Lena i-boost circuit, ngakho-ke i-Vo+Vd>Vi, i-inductance iyakhishwa ngalesi sikhathi, ihlinzeka amandla kumthwalo, futhi ishaja i-capacitor yesihlungi esiphumayo.

Okungenhla ukubuka okufushane kwe-BOOST Circuit, okungasebenza njengereferensi yawo wonke umuntu.Inkampani yethu ineqembu eliqinile lezobuchwepheshe futhi ingahlinzeka ngezinsizakalo zobuchwepheshe kumakhasimende.Njengamanje, inkampani yethu inemikhiqizo ehlukahlukene: ehlakaniphilewena, imodyuli ye-optical yokuxhumana, i-optical fibre module, i-sfp optical module, imishini ye-olt, ukushintshwa kwe-Ethernet nezinye izinto zenethiwekhi.Uma udinga, ungaba nokuqonda okujulile.
