Icyiciro cyo kugenzura Thyristor (Ubwoko bwa Alloying)

Ibisobanuro:

Thyristor, izwi kandi ku izina rya Silicon Control Rectifier (SCR), ni igikoresho kinini gifite imbaraga za semiconductor kigizwe n'inzego eshatu za PN.Ku bijyanye n’imikorere, thyristor ntabwo ifite gusa icyerekezo kimwe gusa, ahubwo ifite nuburyo bugenzurwa cyane kuruta ibintu bya silicon ikosora ibintu, ibihugu bibiri gusa byo gutwara no hanze yigihugu, kugirango bigenzure ingufu nini nimbaraga nke, kongera ingufu kugeza magana cyangwa inshuro ibihumbi.Igisubizo kirihuta cyane, gufungura no kuzimya mumasegonda make.Igikorwa cyo kudahuza, nta spark, nta rusaku, mugihe imikorere myiza nigiciro gito.Kubwibyo, cyane cyane muri sisitemu yo gutanga amashanyarazi menshi, thyristor yakoreshejwe cyane mumuzunguruko wa rectifier, static bypass switch, contact-free output switch and other circuit.

Ubuhanga bwo gukora bwa thyristor no gutunganya 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, ubwiza nibikorwa biratera imbere cyane, intsinzi nini nini yagezweho mugukoresha ibikoresho bya elegitoroniki. imirima, 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.Ubumenyi-bwa RUNAU Electronics usibye gucunga ubujyakuzimu bwimbitse, uburinganire bwubuso, ubuvumo bwuzuye hamwe nubuhanga bwuzuye bwo gukwirakwiza, irembo rwagati, impeta yumuzingi byakoreshejwe kugirango bishoboke gukora neza kandi neza cyane bya thyristor, kugirango menya neza imikorere myiza.

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 habeho firime ya aluminiyumu yuzuye hejuru ya silicon wafer, kandi rutheniyumu yashyizwe hejuru ya molybdenum izamura umunaniro mwinshi wumuriro, igihe cyakazi cya thyristor kiziyongera cyane.

Ibisobanuro bya tekiniki

1. Icyiciro cyagenzuwe na thyristor hamwe na chip yo mu bwoko bwa chip yakozwe na RUNAU Electronics, urwego rwa I._TAVkuva 300A kugeza 6000A na V._DRM/V_RRMkuva 800V kugeza 4400V.
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
