Degdega Thyristor

Sharaxaad:

Thyristor beddelka degdega ah, oo leh qaab isku mid ah iyo calaamad u ah xakamaynta wajiga thyristor, halka sifooyinka wanaagsan ee joogtada ah, gaar ahaan sifooyinka firfircoon ayaa looga baahan yahay codsiga soo noqnoqda sare ee hagaajinta, jarista, beddelka iyo wareegga wareegga beddelka.Halbeegyada firfircoon ee thyristor-ka degdega ah waa xawaaraha shid degdega ah iyo xawaaraha balaadhinta shid, ka soo kabashada oo yar, iyo wakhtiga daminta gaaban, heerka sare u kaca heerka sare ee wakhtiga xaadirka ah (di/dt) iyo heerka muhiimka ah kororka danab ka baxsan gobolka (dv/dt).Hadda la qiimeeyay ee thyristor dhaqsaha badan inta jeer ee la qiimeeyay ma yara ama yara dhimmayo marka soo noqnoqoshada sii kordheyso.

Heerka wax soo saarka thyristor degdega ah iyo farsamada farsamaynta ee RUNAU Electronics waxaa laga soo saaray USA tan iyo 1980-meeyadii, iyada oo hormuud u ah wax soo saarka thyristor ee Shiinaha, kooxda farsamada ee RUNAU waxay heleen aqoonta ugu sareysa iyo khibrad wax soo saar oo ku filan in ka badan 30 sano.Aasaaska habka wax soo saarka dhaqameed, farsamoyaqaannada kartida ee RUNAU Electronics waxay soo saareen tignoolajiyada-farshaxanka-farshaxanka ee soo saarista thyristor oo leh astaamo faa'iido leh oo alaabada Yurub ah, tayada iyo waxqabadka ayaa si weyn loo wanaajiyay, guulo badan oo waaweyn ayaa lagu gaadhay codsiyada elektiroonigga ah, oo qiimo badan ayaa loo abuuray shuraakada.

Hordhac:

1. Chip

Chip-ka thyristor ee ay samaysay RUNAU Electronics waa tignoolajiyada alloying sinteed oo la adeegsaday.Waferka silikoon iyo molybdenum-ka waxaa lagu dahaaray aluminium saafi ah (99.999%) oo hoos yimaada faakuum sare iyo jawi heerkul sare ah.Maamulka sifooyinka sintering waa qodobka ugu muhiimsan ee saameeya tayada thyristor.Aqoonta RUNAU Electronics marka lagu daro maaraynta qoto dheer ee isku xidhka Alloy, flatness dusha sare, godka alloy iyo sidoo kale xirfad faafin buuxda, qaabka goobada giraanta, qaab dhismeedka iridda gaarka ah.Sidoo kale farsamaynta gaarka ah ayaa la isticmaalay si loo yareeyo nolosha side qalabka, si xawaaraha dib-u-gudbiyeedka gudbiyaha gudaha si weyn loo dardargeliyo, dib u soo kabashada qalabku waa la dhimay, xawaaraha beddeliddana waa la wanaajiyaa.Cabiraadaha noocan oo kale ah ayaa lagu dabaqay si loo wanaajiyo sifooyinka beddelka degdega ah, sifooyinka gobolka, iyo kor u kaca hantida hadda jirta.Waxqabadka iyo socodsiinta shaqada thyristor waa mid la isku halayn karo oo hufan.

2. Encapsulation

Iyada oo si adag loo xakameynayo fidsanaanta iyo isbarbardhigga waferka molybdenum iyo xirmada dibadda, chip iyo waferka molybdenum ayaa si adag oo dhammaystiran loogu dari doonaa xirmo dibadda ah.Noocan oo kale ah ayaa wanaajin doona iska caabinta qulqulka hadda socda iyo hadda wareegga gaaban ee sare.Iyo cabbiraadda tignoolajiyada uumiga elektarooniga ah ayaa loo adeegsaday si loo abuuro filim aluminium qaro weyn leh oo ku yaal dusha sare ee silikoon wafer, iyo lakabka ruthenium ee lagu dhejiyay dusha molybdenum wuxuu kor u qaadi doonaa caabbinta daalka kuleylka si weyn, waqtiga nolosha shaqada ee thyristor degdeg ah ayaa si weyn loo kordhin doonaa.

Tilmaamaha farsamada

1. Thyristor-ka degdega ah ee leh nooca alloy-ga oo ay soo saartay RUNAU Electronics, kala duwan ee I_TAVlaga bilaabo 200A ilaa 4000A iyo V_DRM/V_RRMlaga bilaabo 1200V ilaa 4500V.
2. I_GT, V_GTiyo aniga_Hwaa qiyamka tijaabada ah 25 ℃, ilaa si kale loo sheego, dhammaan cabirrada kale waa qiyamka tijaabada ee hoos yimaada T_jm;
3. I²t=I²F SM×tw/2, tw= Sinusoidal kala badh mawjadaha balac ee hadda jira.50Hz, I²t=0.005I²FSM (A²S);
4. At 60Hz: I_FSM(8.3ms)=I_FSM(10ms)×1.066,T_j=T_j;I²t(8.3ms)=I²t (10ms)×0.943,T_j=T_jm
