Ese ari maviri buck wedunhu uye anosimudzira dunhu akakosha maseketi mukugadzira hardware, kunyanya kune hungwaruONUsuye OLT zvishandiso.Iyo VOICE inoshanda mukatiONUdhizaini inoshandisa iyo inosimudzira dunhu kuti ikwidze zvakananga voltage uye kupa simba kune ekunze mafoni.Nzira yakanakisa yekunzwisisa iyo inosimudzira dunhu ndeyekunyatsonzwisisa voltage uye ikozvino yechikamu chimwe nechimwe chedunhu, Kusangana nemamwe matambudziko kunogona kunyatso ratidza dambudziko.Semuenzaniso, chii chinoitika kana inductance inowedzera?Chii chinoitika kana capacitance ichiwedzera?Chii chinokonzera kushanda kwefrequency?Tevere, kambani yedu ichakutsanangurira.
Chekutanga pane zvese, ngatitaure nezve iyo inonyanya kukosha yekushanda musimboti weBOOST dunhu: Mumufananidzo uri pazasi, iyo MOS transistor is switch.Chero bedzi iyo kumhanya ichimhanya zvakakwana (iyo switching frequency yakakwira zvakakwana), iyo yekubatidza uye yekudzima nguva (yekuchaja uye yekuburitsa nguva) inodzorwa zvakanaka, uye yakasanganiswa neinobuda sefa capacitor, iyo yakagadzikana Vo inogona kuwanikwa (izwi voltage yehungwaru hweduONUinowanzoita 48V), inova voltage inobuda.
Kana switch yabatidzwa, inductor L inomiswa, diode inogurwa, uye Vi inochaja iyo inductor L. Iyo voltage kumagumo ese einductor ndeye Vi (kazhinji 12V yeONUmagetsi).Kana iyo switch ikava isina conductive, nekuti inductor L yakatochajwa uye pane ikozvino inoyerera kuburikidza nayo, ikozvino pamigumo miviri yeinductor haigone kungoerekana yachinja.Naizvozvo, voltage ichave yakanyengerwa kugadzira iyo diode pane chaiyo maitiro.Iyo inobuda voltage Vo inogara iripo, uye diode conduction voltage inodonha iVd, saka vhezheni iri kumucheto wekurudyi weinductor ndeye Vo + Vd, uye voltage kumucheto kuruboshwe kweinductor ndiyo simba rekuisa Vi.Iyi idunhu rinosimudzira, saka Vo + Vd> Vi, iyo inductance inoburitswa panguva ino, ichipa simba kumutoro, uye kuchaja iyo inobuda sefa capacitor.

Iyo inobuda voltage Vo inogara iripo, uye diode conduction voltage inodonha iVd, saka vhezheni iri kumucheto wekurudyi weinductor ndeye Vo + Vd, uye voltage kumucheto kuruboshwe kweinductor ndiyo simba rekuisa Vi.Iyi idunhu rinosimudzira, saka Vo + Vd> Vi, iyo inductance inoburitswa panguva ino, ichipa simba kumutoro, uye kuchaja iyo inobuda sefa capacitor.
Izvo zviri pamusoro ipfupi pfupiso yeBOOST Circuit, iyo inogona kushanda sereferensi kune wese munhu.Kambani yedu ine yakasimba tekinoroji timu uye inogona kupa nyanzvi tekinoroji masevhisi kune vatengi.Parizvino, kambani yedu ine zvigadzirwa zvakasiyana-siyana: zvakangwaraonu, kutaurirana optical module, optical fiber module, sfp optical module, olt midziyo, Ethernet switch uye zvimwe network michina.Kana uchida, unogona kuva nokunzwisisa kwakadzama.
