1. Iikhonsepthi ezisisiseko kunye nemigaqo yeTrios
I-Tolisotor, njengelungu eliphambili losapho loTensertor, lidlala indima engenakuphikiswa kwiziphaluka ze-elektroniki.Inamacandelo amathathu asisiseko: isiseko, i-Emitter kunye nomqokeleli.Apha, sigxile ikakhulu kwi-NPN Traisayo.Iimpawu eziphambili ze-NPN Inokuchazwa yisekethe elilinganayo, apho unxibelelwano phakathi kolu nxibelelwano kunye ne-Emitter ilingana ne-diode, kunye nonxibelelwano phakathi komqokeleli kunye ne-Emitter inokuthathwa njengomqeshiso ohlengahlengisiweyo.Ukuxhathisa kolu ncedo lwahluka kakhulu, ukusuka kwi-OHMS embalwa ukuya kwi-infinity (i-Counter yeSekethe).
Ngaphambi kokuba uxubushe ngobunzulu, kufuneka sicacisa i-equising ye-NPN TODISTOR: IC = β = βib.Kule nxation, ib imele okwangoku ukusuka kwi-Emitter, i-IC yimqokeleli kumqokeleli kwi-Emitter, kunye ne-β yimeko ye-amboode.Oku kuninzi kukugqitywa kokusekwe kwinkqubo yemveliso, kwaye ixabiso layo lihlala phakathi kwamashumi kunye namakhulu.Nangona kunjalo, kuya kufuneka kuqatshelwe ukuba i-triode ilufezekisa le mpembelelo ye-ambooder ngokuhlengahlengisa ukunganyangeki okulinganayo (RCE) phakathi komqokeleli kunye nokuqubha.Xa i-RCE ihlengahlengiswa kwixabiso eliphantsi kakhulu kodwa asakwazi ukufezekisa i-IC = ib, siyibiza ngokuba yi-"ill "Kwelinye icala, xa i-RCE ihlengahlengiswa kwixabiso eliphezulu kakhulu kodwa ayikwazi ukufezekisa i-IC = βib, ibizwa ngokuba yi-"egayiwe".Ngokufanelekileyo, i-tristor kufuneka isebenze kwingingqi ye-amlpha, oko kukuthi, imeko ye-IC = βib.
2. UKWAZO
Kwindlela yoyilo yesekethe ekhompyuter, ukusetyenziswa kwemithombo yolwazi eqhubekayo kubalulekile.Ukuthatha iCaphucial capcial Dance eQhelekileyo kwisekethe njengomzekelo, ukukhululwa i-IC = UC / R, apho i-UC imele i-voltage yeCapacitoti.Kuba i-cancial voltage incipha ngokuhamba kwexesha, ukukhululwa ngokwesiko akukho rhoqo.Nangona kunjalo, ngokusebenzisa i-NPN Traisayo, sinokwakha isekethe yonke indawo.
Kwindlela enjalo yesekethe, ukukhululwa okwangoku kwiCapacitoti engazimeleyo kwi-voltage yayo.Umzekelo, ucinga ukuba ixabiso lesekethe liyi-4.3v (libalwe njenge-5V thabatha i-5v), ke sinokufumana ukuba i-IC (i-ic i-IC) ilingana ne (ibala nje(Phinda-phinde (i-Emitter).Le nkqubo yokubala isekwe kwiPropathi ebalulekileyo: I-Triode kufuneka isebenze kwindawo ye-Amboris, oko kukuthi, i-IC = yeyoneliseki.Ukujonga ukuba ixabiso eliqhelekileyo le-β likwi-odolo amaxesha ali-100, okt inokuthathwa njengelingana ne-IC.
3. Inkqubo yesisombululo sesekethe i-triode
Xa uyila kunye nokuhlalutya iisekethe ze-wiristor, sihlala silandela ezi nyathelo lilandelayo: qala ucinge ukuba i-ICL-gener isebenza kwingingqi ye-Amation kwaye ifezekise imiqathango ye-IC = i-IC≈ie;Emva koko i-uce i-uce (i-voltage phakathi komqokeleli kunye ne-Emitter) ngokusekwe kwiziphumo zokubala) zisengqiqweni ukufumanisa ukuba ingcinga yangaphambili iyinyani.Umzekelo, ekuthandeni i-voltage jikelele kwi-10V, singabala i-uce ukuba ibe yi-5.7V, ethi inike i-RCE ngexabiso le-5.7k ohms.Oku kuthetha ukuba ngokuhlengahlengisa i-RCE ukuya kwi-5.7k OHMS, i-toristor inokugcina ukukhutshwa kweCapacitor ye-1MA.Ngokufanayo, xa i-Capacitor i-8v, i-uce yi-3.7v kwaye i-RCE yi-3.7k ohms, ukuze ukukhululwa okwangoku kugcinwa kwi-1ma.
Nangona kunjalo, xa i-Capacitor ihla ngezantsi komda othile, onje nge-3V, siya kufumanisa ukuba iziphumo ezibaliweyo ze-uce iba lixabiso elibi (-1.3v), oko ngokucacileyo kucacile.Oku kubonisa ukuba nokuba i-RCE ihla ukuya kwi-0 OHMS, imeko ye-IC = βib ayinakuhlutha.Ke ngoko, xa i-Capacitor ihla ngezantsi kwe-4.3v, i-topiser ayisayi kuphinda isebenze kwingingqi ye-Ambocilisor kodwa ingena kwingingqi yombuso.Kufanelekile ukuba uqaphele ukuba kwizicelo ezenziwayo, ukuxhathisa phakathi komqokeleli kunye ne-Emitter akunakuncitshiswa ukuya kwi-0ω, ke into ephantsi ye-Uce ingancitshiswa kuphela kwi-0.2V.Eli xabiso libizwa ngokuba yi-tube ye-tube ye-tubrage voltage yehla i-uces.
4. UKUSETYENZISWA KWEENKONZO ZE-PNP kwiMithombo yePen
Kwahlukile kuhambo lwe-NPN, lokuphumeza umthombo oqhubekayo oqhakamshelayo, kufuneka sisebenzise ii-PNP zokuhambisa.Umgaqo wokuSebenza kunye nolwakhiwo lwe-PNP ye-PNP zahlukile kwi-NPN, kodwa idlala indima ebalulekileyo ekufezekiseni umthombo oqhubekayo oqhubekayo.Kwindlela yokuhamba kwe-PNP, indlela yokuhamba kwayo ngoku ichasene ne-NPN Tofistor, ebonelela bhetyebhetye ngakumbi ekuyini iindlela ezahlukeneyo zesekethe ze-elektroniki.
