Zokambirana zakuya ndi zothandiza za PN Junction Semiconductor amaso
Monga chinthu chofunikira kwambiri muukadaulo wamagetsi, ntchito ndi kapangidwe ka zigawo za PNED PAN ndizofunikira kuti mumvetsetse gawo lonse la semiconduct.Nkhaniyi ikufuna kufotokoza mu mawu osavuta, mfundo zofunika kwambiri komanso kufunikira kwa chipangizocho mu kugwiritsa ntchito, makamaka zotsatira zake.Kapangidwe ka zinthu ndi mfundo zogwirira ntchito za PN medics sikofunikira kwambiri kwa maluso omwe amagwiritsa ntchito pa ntchito zamagetsi, komanso kwa akatswiri ndi okonda omwe akufuna kumvetsetsa mfundo zamagetsi akuya.
Zambiri Zomanga za PN Junction Dide
A PN Junction DIDOD imapangidwa ndi n-mtundu semiconductor ndi p-lembani semiconductor.Kuphatikiza kwa zinthu ziwiri izi semicoctoctoc kumapanga ma cn.Kuti timvetsetse luntha, nthawi zambiri timafotokoza madongosolo a PN meniction ponena za mtundu wa chithunzi (a).Mu kapangidwe kameneka, n-mtundu Semiconduckiring imagwira ntchito ngati maziko, ndipo p-mtundu wa Shemiconductor amalowa mkati mwake.Kuphatikiza apo, mawonekedwe amtundu umodzi omwe awonetsedwa pa chithunzi (B) ndi choyimira china cha gawo la AA '.Kuphatikiza apo, chithunzi (c) chikuwonetsa chizindikirocho ndi njira yolowera ya PN meniction DNE DIDED, yomwe imapereka maziko omvetsetsa mawonekedwe ake.
Mukamafufuza zamagetsi, iv (vol vol vonal) yopitsirana ya PN meniction DNOD DIODD DIODED yake yapadera ndi yosinthira.Kutsogolo kwa nyumba yabwino, pomwe mphamvu yabwino ikagwiritsidwa ntchito ku DIODED, kuchuluka komwe kumawonjezeka ndi voliyumu.Under reverse bias, that is, when a negative voltage is applied, the current is almost zero, indicating the unidirectional conduction characteristics of the PN junction diode.Komabe, ngati magetsi olakwika akupitiliza kuwonjezeka, ma daide atha kuwonongeka, ndikupangitsa kuchuluka kwapano, komwe ndi mlandu wapadera m'magetsi.
Kukonzanso Mphamvu ya PN Junction Daide
Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi ma action a PNGES ndi ntchito yawo yokonzanso, yomwe ndi kuthekera kwawo kusinthasintha kwapano (AC) kuwongolera kwaulere (DC).Kudzera m'magawo oyambira omwe awonetsedwa Chithunzi (a), titha kuwona njira yogwirira ntchito theka-for information, yomwe ilipo kaleMphamvuyo siyinali yoyipa, sipadzayenda.Mphamvu ya kukonzedwanso mu theka ili ikhoza kuphatikizidwanso ndi ma cartactors ofanana ndi ena, pamapeto pake amakwaniritsa zotulutsa zokhazikika za DC.
Kutanthauzira komanso kufunikira kwa zojambula zamakendi
Mukamamvetsetsa kwambiri mfundo zogwirira ntchito zamagulu a PNGES, zojambula zamakenga zimapereka njira yothetsera njira yopezera ndi kumvetsetsa machitidwe a ma elecontrons mu seramonducton.Semonictoct ikakhala pamalo okhazikika, mwachitsanzo, kugwiritsa ntchito voliyumu ya -0.5v mbali yakumanja imapanga disiri lamagetsi, zomwe zimapangitsa chithunzi cha mphamvu, ndikupangitsa chithunzi cha mphamvu kuti chiziwoneka chitawoneka.Mu boma lino, kayendedwe ka ma elekitoni ndi mabowo amatenga mbali yofunika kwambiri pamagetsi a zamagetsi a pn.Ma elekitons amasunthira kulowera kutsika, pomwe mabowo amachita zosiyana.Kusuntha kwawo ndi kubwezera mwachindunji kumakhudza mayendedwe a PN Junction Dide.
Mukamakambirana zojambula zamagulu amphamvu kale komanso mutangopirira, titha kumvetsetsa momwe dera limakhalira lonse, ndi momwe ma elefukiri amapangidwira munjira ndi mabowo.Kukhalapo kwa osanjikiza ndikofunikira kwambiri kumagetsi a PNGER.Sikuti zimangokhudza mawonekedwe a DIODOD, komanso imakhudzanso magwiridwe ake a volipi osiyanasiyana.
Mwa kusanthula kwakuya kwa kapangidwe kake, mawonekedwe a magetsi ndi kugwiritsa ntchito zitsulo za PNGES pazozungulira zamagetsi, titha kumvetsetsa bwino mfundo ndi kugwiritsa ntchito chida chofunikira ichi.Phunziro ndi kugwiritsa ntchito masiketi a PNGONS PAN sikuti chidziwitso chokha cha mainjiniya ndi akatswiri, komanso chida chamtengo wapatali kwa aliyense amene akufuna kumvetsetsa bwino zaukadaulo wamagetsi.
