I-component ye-semiconductor elula-i- diode- ifomisa imisebenzi eyahlukahlukeneyo enxulumene nenjongo yayo yokulawula ulawulo lokuhamba kwamandla kagesi. Iidisodes zivumela ukuba ngoku ukuhamba kwazo zilandelelanise kuphela.
Idiode ezisebenzayo ezibonakalayo zibonakala zivuliwe ezijikelezayo kunye neendleko ezimbi kwaye zibukeka njengezijikelezi ezifutshane. Kodwa ngenxa yokuba ididi zivuma ukungazi kakuhle, ulwalamano lwabo lwamanje-to-vol nonlinear.
Ngaloo ndlela, uya kufuna ukudibana needayetet ye diode ukuze ubone igrafu yekhalo lalo nawuphi na umbane we-diode ohambelana naso kwangoku, ukwenzela ukuba ukhethe idiode efanelekileyo yeprojekthi yakho ethile.
Izicelo zeDiodes
Nangona nje zixhobo ezilula ze-pin-semiconductor, ii-diodes zibalulekile kwi-electronics yesimanje. Ezinye zezicelo eziqhelekileyo zezididi ziquka:
- Ukubuyisela i-voltage, njengokuba i-AC ibe yi-DC voltages
- Ukukhupha iimpawu ukusuka ekunikezeni
- Ukulawula ubukhulu bomqondiso
- Ukuxuba imiqondiso
Ukuguqulwa kwamandla
Isicelo esisodwa esibalulekileyo sesdidi kukuguqula amandla ase-AC ukuya kumandla kagesi. Idiode enye okanye ezine idiode zingasetyenziselwa ukuguqula amandla angama-110V emakhaya ukuya kwi DC ngokwenza isigxina (idiode enye) okanye u-wave-full (ezine diode). I-diode yenza oku ngokuvumela isiqingatha se-AC ifom yefom yefayili ukuhamba ngayo. Xa le pulsi yamandla isetyenziselwa ukuhlawula i-capacitor, umbane oveliswayo ubonakala ube ngumbane ongezantsi we-DC kunye ne-small ripple voltage. Ukusebenzisa i-red-wave rectifier eyenza le nkqubo iphumelele ngakumbi ngokuhambisa imizila ye-AC ukuze iindidi ezintle kunye nezingalunganga zengxangxube ye-sine wavele zibonwe nje ngokuba zizimpembelelo ezintle, ngokuphindaphindiweyo ukuphindwa kabini kwimizila yefuthe lokufakelwa kwi-capacitor, inceda ukuyigcina ihlawulwe kwaye ihambise umbane ozinzile.
Iidisodes kunye nama-capacitors nazo zingasetyenziselwa ukudala inani leendidi zamaphaneli ezithatha umbane ukuba zithathe i-AC encinane yombane kwaye zandise ukuze zenze iziphumo eziphezulu kakhulu zamandla. Iziphumo zombini ze-AC kunye ne-DC ziyakwenzeka ngokusebenzisa ukulungiswa okufanelekileyo kwama-capacitors kunye needidi.
Ukutyalwa kweMpawu
Ukusetyenziswa okuqhelekileyo kweedodesi kukususa icandelo elibi lomqondiso we-AC. Ngenxa yokuba inxalenye engafanelekanga yefom ye-AC idla ngokufana nesiqingatha esihle, ulwazi oluncinci kakhulu lulahlekile kule nkqubo yokuluqhawula, olukhokelela ekusebenziseni i-signal eyiyo.
Ukuchithwa kwamagama okusetyenziswa ngokuqhelekileyo kusetyenziswa kwii- radios njengenxalenye yenkqubo yokucoca ukukunceda ukukhipha isantya somsakazo kumbane ophethe.
Ukukhuselwa kwamanzi
Iidisodes zisebenza kakuhle kunye nezixhobo zokukhusela kwizinto eziphathekayo zekhompyutha. Xa zisetyenziswe njengezixhobo zokukhusela umbane, ii-diodes azikho migaqo phantsi kweemeko eziqhelekileyo zokusebenza kodwa ngokukhawuleza zifutshane nanoma yiyiphi i-high-vol spike emhlabathini apho ingenakonakalisa i-circuit edibeneyo. Idiode ezikhethekileyo ezibizwa ngokuba yi- voltage suppressionors ezidlulileyo zenzelwe ngokukodwa ukukhuselwa kwamandla angaphezulu kwaye zikwazi ukuphatha iipikhi zamandla amakhulu kwixesha elifutshane, iimpawu eziqhelekileyo ze-voltage spike okanye ukutshatyalaliswa kwamandla, okuqhelekileyo ukuwonakalise izinto kunye nokunciphisa ubomi bomkhiqizo wekhompyutha.
Ngokufanayo, i-diode inokulawula umbane ngokukhonza njenge- clipper okanye i- limiter- injongo ekhethekileyo eyenza i-voltage engayidlulisela kuyo kwindawo ethile.
Ulawulo olukhoyo
Isicelo esisisiseko sezididi ukuhamba kwangoku kwaye uqinisekise ukuba uhamba kuphela ngendlela efanelekileyo. Omnye ummandla apho ubuchule bokulawulwa kweedayidi ezisetyenziswayo ngokusetyenziswa kwimpumelelo kuguqulwa kwamandla avela kumbane wokunikezelwa kwamandla osebenza kwibhetri. Xa ifowuni ixhunyiwe kwaye ihlawule-umzekelo, ifowuni okanye ukunikezelwa kwamandla okungaxininiseki-ifowuni kufuneka ifake amandla ngaphandle kokunikezelwa kwamandla angaphandle ngaphandle kwebhetri, kwaye ngelixa ifowuni ifakwe kwibhetri kufuneka ibonise amandla nokubuyisela kwakhona. Ngokukhawuleza ukuba umthombo wamandla ususwe, ibhetri kufuneka inikwe amandla ifowuni ukuze kungaphazamiseki ukuphazamiseka ngumsebenzisi.
Umzekelo omhle wolawulo olukhoyo ngoku kubuyiselwa ngoku. Cinga, umzekelo, imoto yakho. Xa ibhetri yakho ifa kwaye umntu odlulayo unika ithuba lokunceda ngeentambo ze-jumper, ukuba udibanisa umyalelo wezixhobo ezibomvu nezamnyama awuyi kutshaya inkqubo yombane yemoto yakho ngenxa yeedayidi ezikufutshane nebhetri ibhanki ekhoyo engafanelekanga.

Iikhomputha zisebenza kwibhinari-elwandle elingapheliyo lwama-zero kunye kunye. Imigca yesigqibo sombhinqa kwi-computing isekelwe kumasango angqiqo anikwe iiladi ezilawula ukuba ngaba utshintshi luya ("1") okanye ucime ("0"). Nangona ikhulu lezigidi zediode zivela kwiiproseshini zanamhlanje, zisebenza ngokufanayo nezididi ozithengayo kwisitoreji se-electronic-esincinane kakhulu.
Diodes kunye noKhanya
I-flashlight ye-LED yinto nje i-flashlight ekukhanyeni kwayo kukhanya kwi-diode ekhanyayo. Ekubeni kwimizi emihle, ii-LED ziyavutha.
I-photodiode, ngokuchaseneyo, yamkela ukukhanya ngumbonisi (njengepaneli yelanga yelanga) kwaye iguqula olo khanyiso kwixabiso elincinane langoku.
