IGBT vs Thyristor
Thyristor thiab IGBT (Insulated Gate Bipolar Transistor) yog ob hom khoom siv hluav taws xob semiconductor nrog peb lub davhlau ya nyob twg thiab ob qho tib si siv los tswj cov dej ntws. Ob lub cuab yeej muaj lub davhlau ya nyob twg tswj hwm hu ua ' rooj vag', tab sis muaj cov thawj coj sib txawv ntawm kev ua haujlwm.
Thyristor
Thyristor yog ua los ntawm plaub txheej txheej semiconductor (hauv daim ntawv ntawm P-N-P-N), yog li, muaj peb PN junctions. Hauv kev tshuaj xyuas, qhov no suav tias yog ib qho sib txuas ua ke ntawm cov transistors (ib qho PNP thiab lwm yam hauv NPN teeb tsa). Sab nraud P thiab N hom semiconductor txheej yog hu ua anode thiab cathode feem. Electrode txuas rau sab hauv P hom semiconductor txheej yog hu ua ' rooj vag'.
Nyob hauv kev ua haujlwm, thyristor ua haujlwm thaum lub mem tes muab rau lub rooj vag. Nws muaj peb hom kev ua haujlwm hu ua 'rov qab thaiv hom', 'hom thaiv kev thaiv' thiab 'kev coj mus tom ntej'. Thaum lub rooj vag tau tshwm sim nrog lub mem tes, thyristor mus rau 'kev coj mus tom ntej' thiab ua haujlwm kom txog thaum lub sijhawm tam sim no dhau los ua qis dua qhov pib 'tuav tam sim no'.
Thyristors yog cov khoom siv hluav taws xob thiab feem ntau lawv siv rau hauv cov ntawv thov uas muaj cov khoom siv hluav taws xob siab thiab qhov hluav taws xob. Daim ntawv thov thyristor siv feem ntau yog tswj cov dej hloov pauv.
Insulated Gate Bipolar Transistor (IGBT)
IGBT yog ib qho khoom siv semiconductor nrog peb lub davhlau ya nyob twg hu ua 'Emitter', 'Colector' thiab 'Gate'. Nws yog ib hom transistor, uas tuaj yeem tswj tau lub zog ntau dua thiab muaj kev hloov pauv siab dua ua rau nws ua haujlwm tau zoo. IGBT tau tshaj tawm rau kev lag luam hauv xyoo 1980s.
IGBT muaj qhov sib xyaw ua ke ntawm MOSFET thiab bipolar junction transistor (BJT). Nws yog rooj vag tsav zoo li MOSFET thiab muaj cov yam ntxwv tam sim no zoo li BJTs. Yog li ntawd, nws muaj qhov zoo ntawm ob qho tib si siab tam sim no tuav lub peev xwm thiab kev tswj tau yooj yim. IGBT modules (muaj ntau yam khoom siv) tuav kilowatts ntawm lub zog.
In luv:
Qhov txawv ntawm IGBT thiab Thyristor
1. Peb lub terminals ntawm IGBT hu ua emitter, collector thiab rooj vag, whereas thyristor muaj terminals hu ua anode, cathode thiab rooj vag.
2. Lub rooj vag ntawm lub thyristor tsuas yog xav tau lub mem tes hloov mus rau hauv kev coj ua, qhov IGBT xav tau qhov txuas txuas ntxiv ntawm qhov rooj voltage.
3. IGBT yog ib hom transistor, thiab thyristor yog suav tias yog nruj ob khub ntawm transistors hauv kev tsom xam.
4. IGBT tsuas muaj ib qho kev sib tshuam PN, thiab thyristor muaj peb ntawm lawv.
5. Ob lub cuab yeej siv rau hauv daim ntawv thov muaj zog.
