Magawo onse a buck ndi boost circuit ndi mabwalo ofunikira pakupanga ma hardware, makamaka anzeruONUndi zida za OLT.VOICE imagwira ntchito muONUkapangidwe kamagwiritsa ntchito chigawo cholimbikitsira kuti chiwonjezeke mwachindunji ma voliyumu ndikupereka mphamvu kumafoni akunja.Njira yabwino yomvetsetsera mayendedwe olimbikitsira ndikumvetsetsa bwino mphamvu yamagetsi ndi momwe gawo lililonse laderali likukhalira, Kukumana ndi zovuta zina kumatha kuwonetsa vuto.Mwachitsanzo, chimachitika ndi chiyani pamene inductance ikuwonjezeka?Kodi chimachitika ndi chiyani pamene capacitance ikuwonjezeka?Kodi ma frequency ogwirira ntchito amakhudza bwanji?Kenako, kampani yathu ikufotokozerani.
Choyamba, tiyeni tikambirane mfundo yofunika kwambiri yoyendetsera dera la BOOST: Pachithunzi chomwe chili pansipa, MOS transistor ndi chosinthira.Malingana ngati liwiro likuthamanga mokwanira (kusinthasintha kwafupipafupi kumakhala kokwanira), nthawi yotsegula ndi yotseka (nthawi yolipira ndi kutulutsa) imayendetsedwa bwino, ndikuphatikizidwa ndi capacitor yotulutsa fyuluta, Vo atha kupezeka (mawu okhazikika). voteji wanzeru zathuONUnthawi zambiri ndi 48V), yomwe ndi mphamvu yotulutsa.
Chosinthiracho chikayatsidwa, inductor L imakhazikika, diode imadulidwa, ndipo Vi imayitanitsa inductor L. Mphamvu yamagetsi pamalekezero onse a inductor ndi Vi (nthawi zambiri 12V kwaONUmagetsi).Kusinthako kukakhala kopanda conductive, chifukwa inductor L idayimbidwa kale ndipo pali pano ikuyenda modutsa, zomwe zili kumapeto onse a inductor sizingasinthe mwadzidzidzi.Chifukwa chake, magetsi amapangidwa kuti apange diode pamayendedwe oyenera.Voliyumu yotulutsa Vo imakhala yosasinthika, ndipo kutsika kwa voliyumu ya diode ndi Vd, kotero voteji kumapeto kumanja kwa inductor ndi Vo + Vd, ndipo voteji kumapeto kumanzere kwa inductor ndikulowetsa mphamvu Vi.Ichi ndi dera lolimbikitsa, kotero Vo + Vd> Vi, inductance imatulutsidwa panthawiyi, ikupereka mphamvu pa katunduyo, ndikulipiritsa chotulutsa fyuluta.

Voliyumu yotulutsa Vo imakhala yosasinthika, ndipo kutsika kwa voliyumu ya diode ndi Vd, kotero voteji kumapeto kumanja kwa inductor ndi Vo + Vd, ndipo voteji kumapeto kumanzere kwa inductor ndikulowetsa mphamvu Vi.Ichi ndi dera lolimbikitsa, kotero Vo + Vd> Vi, inductance imatulutsidwa panthawiyi, ikupereka mphamvu pa katunduyo, ndikulipiritsa chotulutsa fyuluta.
Zomwe zili pamwambazi ndizofotokozera mwachidule za BOOST Circuit, zomwe zitha kukhala zofotokozera aliyense.Kampani yathu ili ndi gulu lolimba laukadaulo ndipo imatha kupereka chithandizo chaukadaulo kwa makasitomala.Pakadali pano, kampani yathu ili ndi mitundu yosiyanasiyana: yanzeruinu, gawo lolumikizana la kuwala, gawo la optical fiber, sfp optical module, zida za olt, switch ya Efaneti ndi zida zina zamtaneti.Ngati mukufunikira, mutha kukhala ndi chidziwitso chozama.
