Fast Switch Thyristor (taxane YC heerka sare ah)

Sharaxaada

Halbeegga wax-soo-saarka GE iyo tignoolajiyada farsamaynta waxaa la soo bandhigay oo ay shaqaalaysiisay RUNAU Electronics ilaa 1980-meeyadii.Xaaladda wax-soo-saarka iyo tijaabinta oo dhammaystiran waxay si buuxda ula mid ahayd shuruudaha looga baahan yahay suuqa Maraykanka.Hormoodka wax soo saarka thyristor ee Shiinaha, RUNAU Electronics waxay siisay farshaxanka qalabka elektiroonigga ah ee dawladda USA, wadamada Yurub iyo isticmaalayaasha caalamiga ah.Waa mid aqoon sare leh oo ay qiimeeyeen macaamiishu iyo guulo waaweyn 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 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 degdeg ah oo leh nooca aluminiumka ah oo ay soo saartay RUNAU Electronics oo awood u leh inay bixiso badeecadaha si buuxda ugu qalma heerka USA.
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
