I-Phase Control Thyristor (Uhlobo Lwengxubevange)

Incazelo:

I-Thyristor, eyaziwa nangokuthi i-Silicon Control Rectifier (SCR), iyidivayisi ye-semiconductor enamandla amakhulu ehlanganisa izakhiwo ezintathu ze-PN.Ngokusebenza, i-thyristor ayinayo kuphela i-unidirectional conductivity, kodwa futhi inokulawulwa okubaluleke kakhulu kune-silicon rectifier element, okuyizimo ezimbili kuphela zokuqhuba kanye ne-off-state, ukulawula amandla amakhulu ngamandla amancane, ukukhuliswa kwamandla kuze kufike kumakhulu noma izikhathi eziyizinkulungwane.Ukusabela kuyashesha kakhulu, kuvula futhi kucishwe kumasekhondi amancane.Ukusebenza okungaxhumene nabo, akukho zinhlansi, akukho msindo, kuyilapho ukusebenza kahle okuphezulu nezindleko eziphansi.Ngakho-ke, ikakhulukazi ohlelweni lokuphakelwa kwamandla aphezulu, i-thyristor isetshenziswe kabanzi kumjikelezo wokulungisa kabusha, i-static bypass switch, switch-free output switch kanye nezinye izifunda.

Izinga lokukhiqiza i-thyristor kanye nobuchwepheshe bokucubungula be-RUNAU Electronics yethulwa e-USA kusukela ngo-1980, njengephayona lokukhiqiza i-thyristor e-China, ithimba lezobuchwepheshe le-RUNAU lalithole ulwazi oluphambili nolwazi olwanele lokukhiqiza iminyaka engaphezu kwengu-30.Ngokwesisekelo senqubo yokukhiqiza yendabuko, ochwepheshe bamathalenta be-RUNAU Electronics bathuthukise ubuchwepheshe be-art-of-state ekukhiqizeni i-thyristor enezici ezinhle zemikhiqizo yaseYurophu, ikhwalithi nokusebenza kuba ngcono kakhulu, ukuwina okukhulu okuzuziwe ekusetshenzisweni kwamandla kagesi. izinkambu, futhi inani elengeziwe ladalelwa ozakwethu.

Isingeniso:

1. I-chip

I-thyristor chip ekhiqizwa yi-RUNAU Electronics isetshenziswa ubuchwepheshe bokusebenzisa i-sintered alloying.I-silicon ne-molybdenum wafer yashiswa ukuze ihlanganiswe nge-aluminium ehlanzekile (99.999%) ngaphansi kwe-vacuum ephezulu kanye nendawo yokushisa ephezulu.Ukuphathwa kwezimpawu ze-sintering kuyisici esibalulekile sokuthinta ikhwalithi ye-thyristor.Ulwazi lwe-RUNAU Electronics ngaphezu kokuphatha ukujula kwe-alloy junction, flatness surface, i-alloy cavity kanye nekhono eligcwele lokusabalalisa, isango eliphakathi, iphethini yendilinga yendilinga yasetshenziswa ukuze kusebenze ukusebenza okuthembekile nokusebenza kahle kwe-thyristor, ukuze qinisekisa ukusebenza kwekhwalithi ephezulu.

2. Encapsulation

Ngokulawula ngokuqinile ukucaba nokuhambisana kwe-molybdenum wafer kanye nephakheji yangaphandle, i-chip ne-molybdenum wafer izohlanganiswa nephakheji yangaphandle ngokuqinile futhi ngokuphelele.Okunjalo kuzothuthukisa ukumelana kwe-surge current kanye ne-high short circuit current.Futhi ukukalwa kobuchwepheshe bokuhwamuka kwe-electron kwasetshenziswa ukuze kwakhiwe ifilimu ye-aluminium ewugqinsi endaweni eyisicwecwana se-silicon, futhi ungqimba lwe-ruthenium olubekwe phezu kwe-molybdenum luzothuthukisa ukumelana nokukhathala okushisayo, isikhathi sempilo yomsebenzi ye-thyristor sizokwenyuka kakhulu.

Ukucaciswa kobuchwepheshe

1. I-thyristor elawulwa yisigaba ene-alloy type chip ekhiqizwe yi-RUNAU Electronics, uhla lwe-I_I-TAVkusuka ku-300A kuya ku-6000A kanye ne-V_I-DRM/V_I-RRMkusuka ku-800V kuya ku-4400V.
2. I_GT, V_GTnami_Hamanani okuhlola aku-25℃, ngaphandle uma kushiwo ngenye indlela, wonke amanye amapharamitha amanani okuhlola ngaphansi kuka-T._jm;
3. I²t=ngi²F SM×tw/2,tw= Ububanzi besisekelo segagasi le-Sinusoidal uhhafu wamanje.Ku-50Hz, I²t=0.005I²I-FSM(A²S);
4. ngo 60Hz:I_I-FSM(8.3ms)=I_I-FSM(10ms)×1.066,T_j=T_j;I²t(8.3ms)=I²t(10ms)×0.943,T_j=T_jm
