Ingxoxo ejulile nasezindaweni ezisebenzayo zePN Junction semiconductor diodes
Njengengxenye eyisisekelo ebalulekile kubuchwepheshe be-elekthronikhi, umsebenzi kanye nokwakheka kwe-PN Junction Diade kubalulekile ukuqonda yonke inkambu ye-semiconductor.Lo mbhalo uhlose ukuchaza ngamagama alula ukwakhiwa, okusebenzayo kanye nokubaluleka kwale divayisi ye-semiconductor kuzinhlelo zokusebenza ezisebenzayo, ikakhulukazi umphumela wayo wokulungiswa kabusha.Ukwakheka kanye nenqubomgomo yokusebenza yama-dienction dianes e-PN akugcini nje ngokubaluleka okukhulu kulabo ochwepheshe abasebenza kakhulu emsebenzini we-elekthronikhi, kodwa futhi nasezazikweni nabathandi abafuna ukuqonda izimiso ze-elekthronikhi ngokujulile.
Imininingwane yokwakha ye-PN Junction Diode
I-PN Junction Diode yakhiwa nge-N-Type texconductor kanye ne-p-texmonductor.Inhlanganisela yalezi zinto ezimbili ze-semiconductor yakha umhlangano we-pn.Ukwenza lula ukuqonda, sivame ukuchaza ama-PN Junction Diades ngokubhekisisa ekwakhekeni okunezinhlangothi ezimbili (a).Kulesi sakhiwo, i-semiconductor ye-n-semiconductor isebenza njengezisekelo, futhi uhlobo lwe-semiconductor lufakwe kulo.Ngaphezu kwalokho, isakhiwo esisodwa esikhonjiswe kuMfanekiso (b) siyisibonakaliso esithile sesigaba se-AA 'esithombeni (a).Ngaphezu kwalokho, umdwebo (c) ukhombisa uphawu nokuholwa kwamanje kokugeleza kwe-PN Junction Diode, enikeza isisekelo sokuqonda izici zalo zikagesi.
Lapho uhlola izakhiwo zayo zikagesi, i-IV (yamanje-voltage) ijika lemifanekiso ye-PN Junction Diode iveza izici zayo ezihlukile zokuqala kanye nezimpawu zokubuyela emuva.Ku-Card Bias, lapho kufakwa i-voltage evumayo kwi-diode, ukwanda kwamanje okubonakalayo nge-voltage.Ngaphansi kwe-shias reverse, okungukuthi, lapho kufakwa i-voltage engemihle, okwamanje icishe ibe yi-zero, ekhombisa izici zokuvumelana ze-unidirectival ze-PN Junction Diode.Kodwa-ke, uma i-voltage engemihle iyaqhubeka nokwanda, i-diode ingahle ihluleke, ibangele ukwanda okubukhali kwamanje, okuyicala elikhethekile ezingxenyeni zalo kagesi.
Ukulungisa umphumela we-PN Junction Diode
Enye yezinhlelo zokusebenza eziphawuleka kakhulu ze-PN Junction Diaoiode ngumsebenzi wazo wokulungisa, okuyikhono labo lokuguqula ukushintshana kwamanje (ac) ku-Direct yamanje (DC).Ngokusebenzisa umjikelezo oqondile oboniswe kuMdwebo (a), singabona umgomo osebenzayo we-Half-wave rexiffication: lapho i-voltage yokufaka inendawo enhle, okukhona manje kuzogeleza nge-diode ku-ranioder umthwalo, laphoI-voltage ayilungile, intando yamanje ngeke igeleze.Umphumela walesi sakhiwo segagasi-wave ungasheshiswa ngama-capacitors afanayo nezinye izingxenye, ekugcineni uzuze okuthe xaxa kwe-DC.
Ukuhunyushwa nokubaluleka kwemidwebo yebhendi yamandla
Enqubweni yokuqonda ngokujulile umgomo osebenzayo we-PN Junnection Diade, imidwebo yamandla we-band inikeza indlela enembile yokubona nokuqonda ukusebenza kwama-elektronicturers.Lapho i-semiconductor isesimweni esisekelwe esisekelweni, ngokwesibonelo, ukusebenzisa i-voltage ye--0.5v ohlangothini lwesokunene kuzokhiqiza insimu kagesi, okwenza umdwebo webhendi yamandla ukuba avele agxiliwe.Kulesi simo, amaphethini wokunyakaza ama-elektroni kanye nezimbobo adlala indima ebalulekile kwizakhiwo zikagesi ze-PN Junction.Ama-elektroni athuthela emazingeni aphansi wamandla, ngenkathi izimbobo zenza okuphambene.Inqubo yabo yokuhamba nenqubo yokubuyiselwa kwemali ithinta ngqo ukuthuthuka kwe-PN Junction Diode.
Lapho uxoxa ngemidwebo yebhendi yamandla ngaphambi nangemva kokubhidlizwa, singaqonda kangcono ukuthi isifunda kanye nesifunda sasesifundani se-N sasiphelele kanjani, nokuthi isendlalelo se-defetetion sakhiwa kanjani nge-elektroni kanye nezimbobo.Ukuba khona kwesendlalelo se-deletion kubalulekile ezingxenyeni zikagesi ze-PN Junction.Akunakuthinta kuphela ukuthuthuka kwe-diode, kepha futhi kuthinta ukusebenza kwayo ngama-voltages ahlukene.
Ngokuhlaziywa okujulile kwesakhiwo, izici zikagesi kanye nokusetshenziswa kwe-PN Junction Diection emibukeni ye-elekthronikhi, kungaqonda kangcono imigomo yokusebenza kanye nokusebenzisa le divayisi ebalulekile ye-semiconductor.Ucwaningo kanye nokusetshenziswa kwama-dienction dienction diaode akuyona kuphela ulwazi oluyisisekelo lobunjiniyela bama-elekthronikhi kanye nalabo, kodwa futhi nomthombo obalulekile kunoma ngubani ofisa ukuthola ukuqonda okujulile kobuchwepheshe banamuhla be-elekthronikhi.
