Kusintha Kwambiri Thyristor

Kufotokozera:

Fast lophimba thyristor, ndi dongosolo lomwelo ndi chizindikiro cha gawo ulamuliro thyristor, pamene makhalidwe abwino malo amodzi, makamaka zazikulu makhalidwe chofunika ndi mkulu pafupipafupi ntchito rectification, kuwaza, inverter ndi pafupipafupi kutembenuka dera.Magawo amphamvu a thyristor yothamanga ndi liwiro loyatsa ndi liwiro la kukulitsa, kubweza kocheperako, komanso nthawi yochepa yozimitsa, kukwera kwakukulu kwapadziko pano (di/dt) ndi kuchuluka kwamphamvu kwambiri. kukwera kwamagetsi aku off-state (dv/dt).Oveteredwa panopa wa kuthamanga thyristor mkati pafupipafupi oveteredwa si kuchepa kapena kutsika pang'ono pamene pafupipafupi kuchuluka.

The fast switch thyristor kupanga standard and processing technology ya RUNAU Electronics idayambitsidwa kuchokera ku USA kuyambira 1980s, monga mpainiya wopanga thyristor ku China, gulu laukadaulo la RUNAU lidapeza chidziwitso chapamwamba komanso luso lopanga zambiri kwazaka zopitilira 30.Pachiyambi cha njira zopangira zachikhalidwe, akatswiri aluso a RUNAU Electronics adapanga luso laukadaulo laukadaulo popanga thyristor yokhala ndi zinthu zabwino zazinthu zaku Europe, mawonekedwe ndi magwiridwe antchito amakula kwambiri, kupambana kwakukulu komwe kumapezeka muzogwiritsa ntchito zamagetsi zamagetsi, ndipo phindu linapangidwa kwa ogwirizana.

Chiyambi:

1. Chip

Chip thyristor chopangidwa ndi RUNAU Electronics ndi ukadaulo wa sintered alloying womwe umagwiritsidwa ntchito.Silicon ndi molybdenum wafer adatenthedwa kuti agwirizane ndi aluminiyamu yoyera (99.999%) pansi pa vacuum yayikulu komanso kutentha kwambiri.Ulamuliro wa sintering makhalidwe ndiye chinthu chofunika kwambiri kukhudza khalidwe la thyristor.Kudziwa za RUNAU Electronics kuwonjezera pa kuyang'anira kuya kwa aloyi mphambano, flatness pamwamba, aloyi patsekeke komanso kufalitsa luso lonse, mphete yozungulira dongosolo, wapadera chipata dongosolo.Komanso processing wapadera anagwiritsidwa ntchito kuchepetsa moyo chonyamulira chipangizo, kuti mkati chonyamulira recombination liwiro kwambiri inapita patsogolo, n'zosiyana kuchira mlandu wa chipangizo yafupika, ndi liwiro kusinthana bwino chifukwa.Miyezo yotereyi idagwiritsidwa ntchito kukhathamiritsa mawonekedwe osinthira mwachangu, mawonekedwe amtundu, komanso kuchuluka kwa katundu wapano.Kugwira ntchito ndi kuyendetsa kwa thyristor ndikodalirika komanso kothandiza.

2. Kufotokozera

Mwa kuwongolera mosamalitsa kwa flatness ndi kufanana kwa molybdenum wafer ndi phukusi lakunja, chip ndi molybdenum wafer zidzaphatikizidwa ndi phukusi lakunja mwamphamvu komanso kwathunthu.Izi zidzakulitsa kukana kwa ma surge pano komanso apamwamba afupipafupi apano.Ndipo muyeso wa luso elekitironi evaporation anagwiritsidwa ntchito kulenga wandiweyani zotayidwa filimu pa pakachitsulo choyika chopyapyala pamwamba, ndi ruthenium wosanjikiza yokutidwa pa molybdenum pamwamba kumapangitsanso matenthedwe kukana kutopa kwambiri, ntchito moyo nthawi ya kudya lophimba thyristor adzakhala ziwonjezeke kwambiri.

1. Fast switch thyristor yokhala ndi alloy type chip yopangidwa ndi RUNAU Electronics, osiyanasiyana I_{Mtengo wa TAV}kuchokera ku 200A mpaka 4000A ndi V_DRM/V_RRMkuchokera 1200V mpaka 4500V.
2. I_GT, V_GTndi ine_Hndi miyeso yoyesa pa 25 ℃, pokhapokha ngati tafotokozera, magawo ena onse ndi mayeso omwe ali pansi pa T._jm;
