Zombini i-buck circuit kunye ne-boost circuit zizisekethe ezibalulekileyo kuyilo lwe-hardware, ngakumbi kwi-intelligentIi-ONUkwayeOLTizixhobo. 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 transistortshintsha. 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 itshintshaivuliwe, i-inductor L isekelwe, i-diode iyanqunyulwa, kwaye i-Vi ihlawulisa i-inductor L. Umbane kwiziphelo zombini ze-inductor yi-Vi (idla ngokuba yi-12VI-ONUukunikezwa Amandla). Xa itshintshaiba yi-non conductive, kuba i-inductor L sele ihlawuliswe kwaye kukho ikhoyo ngoku ihamba 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 yonxibelelwano yamehlo, imodyuli yefiber ebonakalayo, imodyuli ye-sfp optical,oltizixhobo, Ethernettshintshakunye nezinye izixhobo zenethiwekhi. Ukuba ufuna, unokuba nokuqonda okunzulu.
