Xakamaynta Wajiga Thyristor (Nooca Alloying)

Sharaxaad:

Thyristor, oo sidoo kale loo yaqaano Silicon Control Rectifier (SCR), waa qalab awood sare leh oo ka kooban saddex qaab-dhismeedka PN.Marka la eego waxqabadka, thyristor ma aha oo kaliya in uu leeyahay conductivity unidirectional, laakiin sidoo kale waxa uu leeyahay kontorool ka qiimo badan element silikon rectifier, kaas oo kaliya laba gobol oo conduction iyo off-state, si loo xakameeyo awood weyn oo leh awood yar, kor u qaadis ilaa boqolaal ama kumanaan jeer.Dareen-celinta waa mid aad u degdeg badan, shid iyo dami ilbiriqsiyo yar gudahood.Hawlgalka aan xiriir la lahayn, ma laha dhimbiilo, buuq la'aan, iyada oo waxtarkeedu sarreeyo iyo kharash yar.Sidaa darteed, gaar ahaan nidaamka sahayda sare ee tamarta, thyristor ayaa si weyn loogu isticmaalay wareegga rectifier, beddelka beddelka joogtada ah, beddelka wax soo saarka aan xiriir la lahayn iyo wareegyada kale.

Halbeegga wax-soo-saarka thyristor iyo tignoolajiyada farsamaynta ee RUNAU Electronics waxaa laga soo saaray USA ilaa 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, farsamayaqaannada kartida ee RUNAU Electronics waxay horumariyeen farsamada-farshaxanka-farshaxanka ee soo saarista thyristor oo leh astaamo faa'iido leh oo ka mid ah alaabada Yurub, tayada iyo waxqabadka ayaa si weyn loo wanaajiyey, guulo waaweyn oo waaweyn ayaa lagu gaaray adeegsiga qalabka elektiroonigga ah. beeraha, iyo qiimo badan ayaa loo abuuray la-hawlgalayaasha.

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 in lagu maareeyo qoto dheer ee isku xidhka Alloy, flatness dusha, godka Alloy iyo sidoo kale xirfad faafin buuxda, albaabka xarunta, qaabka goobada giraanta ayaa lagu dabaqay si ay u suurtageliso in la isku halayn karo oo hufan hawlgalka conduction of thyristor, si ay u hubi waxqabadka tayada sare leh.

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 ayaa si weyn loo kordhin doonaa.

Tilmaamaha farsamada

1. Thyristor wejiga kantaroolay oo leh nooca alloy-ga oo ay soo saartay RUNAU Electronics, baaxadda I_TAVlaga bilaabo 300A ilaa 6000A iyo V_DRM/V_RRM800V ilaa 4400V.
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
