Zombini i-buck circuit kunye ne-boost circuit zizisekethe ezibalulekileyo kuyilo lwe-hardware, ngakumbi kwi-intelligentIi-ONUkunye nezixhobo zeOLT.Umsebenzi we-VOICE kwiI-ONUuyilo lisebenzisa isekethe yokunyusa ukonyusa ngokuthe ngqo amandla ombane kunye nokubonelela amandla kwiifowuni zangaphandle.Eyona ndlela ingcono yokuqonda i-boost circuit kukuqonda ngokupheleleyo i-voltage kunye ne-current yecandelo ngalinye lesekethe, Ukuhlangabezana neengxaki kunokukhomba ngokucacileyo indawo yengxaki.Ngokomzekelo, kwenzeka ntoni xa i-inductance inyuka?Kwenzeka ntoni xa i-capacitance inyuka?Yintoni impembelelo yokusebenza rhoqo?Okulandelayo, inkampani yethu iya kukuchazela.
Okokuqala, makhe sithethe ngowona mgaqo usisiseko wokusebenza wesekethe ye-BOOST: Kulo mfanekiso ungezantsi, i-MOS transistor yinto yokutshintsha.Ngethuba nje isantya sikhawuleza ngokwaneleyo (i-frequency yokutshintsha iphezulu ngokwaneleyo), ixesha lokuvula kunye nokucima (ukutshaja kunye nexesha lokukhupha) lilawulwa kakuhle, kwaye lidityaniswe ne-capacitor yokucoca imveliso, iVo ezinzileyo inokufumaneka (ilizwi). amandla ombane wengqondo yethuI-ONUngokuqhelekileyo yi-48V), engumbane ophumayo.
Xa utshintsho luvuliwe, i-inductor L isekelwe, i-diode iyanqunyulwa, kwaye i-Vi ihlawulisa i-inductor L. I-voltage kuzo zombini iziphelo ze-inductor yi-Vi (ngokuqhelekileyo i-12VI-ONUukunikezwa Amandla).Xa umtshintshi ungaba yi-conductive, ngenxa yokuba i-inductor L sele ihlawuliswe kwaye kukho ikhoyo ngoku ehamba ngayo, okwangoku kuzo zombini iziphelo ze-inductor ayikwazi ukutshintsha ngokukhawuleza.Ke ngoko, i-voltage iya kunyanzelwa ukuba yenze i-diode ibe yindlela efanelekileyo yokuziphatha.I-voltage yemveliso yeVo ihlala rhoqo, kwaye i-diode conduction voltage drop yi-Vd, ngoko ke i-voltage ekupheleni kwasekunene kwe-inductor yiVo + Vd, kwaye i-voltage ekupheleni kwekhohlo ye-inductor yigalelo lamandla Vi.Le yisekethe yokunyusa, ngoko i-Vo + Vd> Vi, i-inductance ikhutshwe ngeli xesha, inika amandla kumthwalo, kwaye ihlawulisa i-capacitor yokucoca imveliso.

Oku kungasentla sisishwankathelo esifutshane se-BOOST Circuit, enokusebenza njengesalathiso kumntu wonke.Inkampani yethu ineqela lobugcisa elomeleleyo kwaye inokubonelela ngeenkonzo zobugcisa kubathengi.Okwangoku, inkampani yethu ineemveliso ezahlukeneyo: ezikrelekrelewena, imodyuli ye-optical yonxibelelwano, imodyuli ye-fiber optical, imodyuli ye-sfp optical, izixhobo ze-olt, i-Ethernet switch kunye nezinye izixhobo zenethiwekhi.Ukuba ufuna, unokuba nokuqonda okunzulu.
