Hindura vuba Thyristor

Ibisobanuro:

Hindura byihuse thyristor, hamwe nuburyo bumwe nikimenyetso cyo kugenzura icyiciro cya thyristor, mugihe ibintu byiza biranga static, cyane cyane ibiranga imbaraga birasabwa numuvuduko mwinshi wo gukosora, gukata, guhinduranya no guhinduranya imirongo.Imbaraga zingirakamaro za thyristor yihuta ni kwihuta-kwihuta no kwihuta kwaguka, amafaranga make yo kugarura ibintu, hamwe nigihe gito cyo kuzimya, umuvuduko mwinshi wo kuzamuka kwa leta (di / dt) nigipimo gikomeye cya kuzamuka kwa voltage ya leta (dv / dt).Ikigereranyo cyagenwe cya thyristor yihuta mugihe cyagenwe ntigabanuka cyangwa ngo kigabanuke gato mugihe inshuro ziyongera.

Ikoreshwa ryihuta rya thyristor ikora kandi ikanatunganya tekinoroji ya RUNAU Electronics yatangijwe kuva muri Amerika kuva mu myaka ya za 1980, nkintangarugero mu gukora thyristor mu Bushinwa, itsinda rya tekinike rya RUNAU ryari rimaze imyaka irenga 30 rifite ubumenyi buhanitse kandi rifite uburambe buhagije bwo gukora.Ku shingiro ryimikorere gakondo, abatekinisiye bafite impano ya RUNAU Electronics bari barateje imbere ikoranabuhanga rigezweho rya reta mugukora thyristor hamwe nibyiza biranga ibicuruzwa byu Burayi, ubuziranenge nibikorwa biratera imbere cyane, intsinzi nini yagezweho mubikorwa bya elegitoroniki, kandi agaciro kanini karemewe kubafatanyabikorwa.

Iriburiro:

1. Chip

Chip ya thyristor yakozwe na RUNAU Electronics yacumuye tekinoroji ikoreshwa.Wafer ya silicon na molybdenum yacumishijwe kugirango ivangwe na aluminiyumu yera (99,999%) munsi yubushyuhe bwinshi nubushyuhe bwo hejuru.Imiyoborere iranga gucumura nikintu cyingenzi kigira ingaruka kumiterere ya thyristor.Kumenya-uburyo bwa RUNAU Electronics hiyongereyeho gucunga ubujyakuzimu bwimbitse, uburinganire bwubuso, ubuvumo bwuzuye kimwe nubuhanga bwuzuye bwo gukwirakwiza, uruziga ruzengurutse, imiterere y amarembo adasanzwe.Na none gutunganya bidasanzwe byakoreshejwe kugirango ubuzima bwabatwara bwigikoresho, kugirango umuvuduko wimbere wubwikorezi bwihuta cyane, amafaranga yo kugarura ibintu byaragabanutse, kandi umuvuduko wo guhinduranya uratera imbere kubwibyo.Ibipimo nkibi byakoreshejwe kugirango hongerwe ibintu byihuta byihuta, kuri leta biranga, hamwe no kuzamura umutungo uriho.Imikorere nogutwara imikorere ya thyristor ni iyo kwizerwa kandi neza.

2. Encapsulation

Mugucunga neza uburinganire nuburinganire bwa molybdenum wafer hamwe nububiko bwo hanze, chip na molybdenum wafer bizahuzwa nibikoresho byo hanze neza kandi byuzuye.Bene ibyo bizahindura imbaraga zo kurwanya imiyoboro ya surge nini kandi ngufi.Ikigereranyo cya tekinoroji ya elegitoroniki yakoreshejwe kugirango ikore firime ya aluminiyumu yuzuye hejuru ya silicon wafer, kandi rutheniyumu yashyizwe hejuru ya molybdenum izamura umunaniro mwinshi wumuriro, igihe cyakazi cyo gukora cyihuta cya thyristor kiziyongera cyane.

Ibisobanuro bya tekiniki

1. Hindura byihuse thyristor hamwe na chip yo mu bwoko bwa chip yakozwe na RUNAU Electronics, urwego rwa I._TAVkuva 200A kugeza 4000A na V._DRM/V_RRMkuva 1200V kugeza 4500V.
2. I_GT, V._GTnanjye_Hni ikizamini cyagaciro kuri 25 ℃, keretse bivuzwe ukundi, ibindi bipimo byose nibizamini byagaciro munsi ya T._jm;
3. I²t = I.²F SM × tw / 2, tw = Sinusoidal igice cyumurongo wubugari bwibanze.Kuri 50Hz, I.²t = 0.005I²FSM (A.²S);
4. Kuri 60Hz: I._FSM(8.3ms) = I._FSM(10ms) × 1.066, T._j=T_j;I.²t (8.3ms) = I.²t (10ms) × 0.943, T._j=T_jm
