Kushanda dzekutanga transistor

Transistor - zano kuti Anomhanyira semiconductors ari Electronics. It rakagadzirirwa yokutendeutsa uye amplification kuti zviratidzo zvemagetsi. Kune mhando mbiri mano: munhu nechirwere transistor uye unipolar transistor kana munda.

Kana transistor mhando mbiri muripo vatakuri vanoshanda panguva - makomba uye maerekitironi, inonzi nedambudziko. Kana transistor imwe chete mhando muripo, zviri unipolar.

Chimbofungidzira basa pombi yemvura zvavo. Rakauya bhaudhi - mvura aibuda yakawedzera, akatendeukira mumwe nzira - yokuderedza kana kumisa kuerera. Anoita ichi ndicho musimboti kushanda ari transistor. maerekitironi chete pane mvura yorwizi inoyerera therethrough. Nheyo nokushanda nechirwere transistor mhando kunoratidzwa chokuti kuburikidza ichi wemagetsi mhando mbiri simba vari. Vari rakakamurwa kumusoro, kana chikuru uye diki, kana maneja. Pakazoti kudzorwa pari kunokanganisa vachikwanisa huru simba. Funga munda kushanda transistor. Nheyo huchishanda akasiyana nevamwe. Chobudira mumwe chete goho ano iyo kunobva ambient remagetsi munda.

The nechirwere transistor chakagadzirwa 3 akaturikidzana ari semiconductor, uyewo, Chikurukuru, maviri PN-junctions. Zvakakosha kusiyanisa PNP uye NPN kuchinja uye, naizvozvo, uye transistors. semiconductors aya rakatumbuka Erekitironi uye mugomba conduction.

The nechirwere transistor ane zviteshi matatu. Izvi nechigadziko kuonana, vachisiya centre layer uye vaviri electrodes panguva kumicheto - emitter uye nomuteresi. Tichienzanisa izvi zviviri yokunyanyisa electrodes chawo rukoko chitete chaizvo. Pamwe micheto ari transistor kunzvimbo semiconductor hakusi zvakafanana, ichibata. mumwe semiconductor rukoko dzinongoda kudivi muteresi kuti zvakarurama nokushanda mudziyo uyu anofanira zvishoma, asi mukobvu achienzaniswa kurutivi emitter.

transistor mashandiro zvinotaurwa kunobva panyama kwendangariro. Ngativerengei vashande muenzaniso PNP. NPN womuenzaniso Achashanda yakafanana kunze polarity pamusoro voltage pakati zvakadai zvinokosha kuva muteresi uye emitter. Ichava negwara risiri.

Fuma P-mhando unotora buri kana chokwadi mhosva ions. N-mhando fuma anoumbwa nhingi mhosva maerekitironi. In transistor nhamba edu mumakomba F nharaunda iri yakakura zvikuru kupfuura nhamba maerekitironi mu N.

Kana iwe rinobatanidza munhu voltage tsime pakati zvakadai zvikamu sezvo emitter uye nomuteresi pamusoro transistor kushanda pfungwa dzinobva kuti mumakomba vanokwezvwa danda uye kuunganidza pedyo emitter. Asi kuitika asingadi kuenda. The yemagetsi munda kubva voltage kwaibva asingadi kusvika nomuteresi nekuti makobvu semiconductor emitter rukoko nechigadziko semiconductor rukoko.
Zvadaro batanidza mumwe voltage panobva ane zvakasiyana mubatanidzwa okunze, kureva nechigadziko uye emitter. Zvino makomba inotumirwa Database uye vanotanga kutaura pamwe maerekitironi. The chinokosha pechingoro yakazara maburi. Zvinoguma dzenzvimbo maviri. Big - kubva emitter kusvika muteresi, diki - kubva muzasi kusvika emitter.

With kuwedzera voltage ari Database ari rukoko N achava zvakatowanda mumakomba, mukanyanyisa nechigadziko uno, kuti emitter ano kuchawedzera zvishoma. Izvi zvinoreva kuti kuchinja duku chawo ano zvakakomba zvakakwana yakakura emitter ano. Zvinoguma kukura chiratidzo munhu nechirwere transistor.

Funga misimboti transistor zvichienderana uchishandisa muoti. Kusiyanisa zvakajairika vanoshingaira rudzi, Ivan Kuchin vanoshingaira rudzi, saturation, cutoff muoti.
In kushingaira nzira, ari emitter mhesano kuzarurwa uye kuvharwa nomuteresi Junction. Muna inversion muoti, zvose zvinoitika pasi zvinopesana.
