Byombi buck umuzunguruko hamwe no kuzamura umuzunguruko ningirakamaro zingirakamaro mugushushanya ibyuma, cyane cyane kubanyabwengeONUn'ibikoresho bya OLT.IJWI imikorere muriONUigishushanyo gikoresha imbaraga zumuzingi kugirango uzamure byimazeyo voltage no gutanga ingufu kuri terefone zo hanze.Inzira nziza yo gusobanukirwa imbaraga zuzunguruka nugusobanukirwa neza voltage numuyoboro wa buri gice cyumuzunguruko, Guhura nibibazo bimwe bishobora kwerekana neza ikibazo.Kurugero, bigenda bite iyo inductance yiyongereye?Bigenda bite iyo ubushobozi bwiyongereye?Ni izihe ngaruka zo gukora inshuro?Ubutaha, isosiyete yacu izagusobanurira.
Mbere ya byose, reka tuvuge ihame ryibanze ryakazi ryumuzunguruko wa BOOST: Ku gishushanyo gikurikira, transistor ya MOS ni switch.Igihe cyose umuvuduko urihuta bihagije (guhinduranya inshuro ni ndende bihagije), ku gihe no hanze (igihe cyo kwishyuza no gusohora) bigenzurwa neza, kandi bigahuzwa nibisohoka muyungurura ubushobozi, Vo irashobora kuboneka (ijwi) voltage yubwenge bwacuONUmuri rusange 48V), aribyo bisohoka voltage.
Iyo switch iriho, inductor L irahagarara, diode iracibwa, na Vi yishyuza inductor L. Umuvuduko kumpande zombi za inductor ni Vi (mubisanzwe 12V kuriONUamashanyarazi).Iyo switch ihindagurika, kubera ko inductor L yamaze kwishyurwa kandi hari umuyoboro unyuramo, umuyoboro kumpera zombi za inductor ntushobora guhinduka gitunguranye.Kubwibyo, voltage izaterwa gukora diode kumyitwarire iboneye.Ibisohoka voltage Vo ihoraho, kandi diode itwara voltage igabanuka ni Vd, nuko voltage kuruhande rwiburyo bwa inductor ni Vo + Vd, naho voltage kuruhande rwibumoso bwa inductor ni imbaraga zinjiza Vi.Numuzunguruko uzamura, Vo + Vd> Vi, inductance isohoka muriki gihe, itanga imbaraga kumuzigo, no kwishyuza ibisohoka muyunguruzi.

Ibisohoka voltage Vo ihoraho, kandi diode itwara voltage igabanuka ni Vd, nuko voltage kuruhande rwiburyo bwa inductor ni Vo + Vd, naho voltage kuruhande rwibumoso bwa inductor ni imbaraga zinjiza Vi.Numuzunguruko uzamura, Vo + Vd> Vi, inductance isohoka muriki gihe, itanga imbaraga kumuzigo, no kwishyuza ibisohoka muyunguruzi.
Ibyavuzwe haruguru ni incamake muri make ya BOOST Circuit, ishobora kuba nkibisobanuro kuri buri wese.Isosiyete yacu ifite itsinda rikomeye rya tekiniki kandi irashobora gutanga serivisi tekinike yumwuga kubakiriya.Kugeza ubu, isosiyete yacu ifite ibicuruzwa bitandukanye: bifite ubwengeonu, itumanaho rya optique module, optique ya fibre optique, sfp optique module, ibikoresho bya olt, Ethernet ihindura nibindi bikoresho byurusobe.Niba ukeneye, urashobora gusobanukirwa byimbitse.
