Phase Control Thyristor (mtundu wa alloying)

Kufotokozera:

Thyristor, yomwe imadziwikanso kuti Silicon Control Rectifier (SCR), ndi chipangizo champhamvu kwambiri cha semiconductor chokhala ndi zida zitatu za PN.Pankhani ya ntchito, thyristor sikuti ali ndi madutsidwe unidirectional, komanso ali ndi controllability ofunika kwambiri kuposa silicon rectifier element, amene mayiko awiri okha conduction ndi off-boma, kulamulira mphamvu yaikulu ndi mphamvu yaing'ono, kukulitsa mphamvu mpaka mazana kapena kambirimbiri.Zomwe zimachitika zimathamanga kwambiri, kuyatsa ndi kuzimitsa mumasekondi ochepa.Kugwira ntchito kosalumikizana, palibe zopsereza, phokoso, pomwe magwiridwe antchito apamwamba komanso otsika mtengo.Chifukwa chake, makamaka pamakina apamwamba amagetsi, thyristor yakhala ikugwiritsidwa ntchito kwambiri pamayendedwe owongolera, static bypass switch, switch-free linanena bungwe switch ndi mabwalo ena.

The thyristor kupanga muyezo ndi processing teknoloji 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 zopindulitsa zazinthu zaku Europe, mawonekedwe ake ndi magwiridwe antchito amakula kwambiri, kupambana kwakukulu komwe kumapezeka pakugwiritsa ntchito mphamvu zamagetsi. minda, ndipo mtengo wochulukira udapangidwa kwa anzawo.

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 alloy mphambano, flatness pamwamba, aloyi patsekeke komanso kufalitsa luso lonse, pakati chipata, mphete yozungulira chitsanzo anagwiritsidwa ntchito kuti athe odalirika ndi mkulu imayenera conduction ntchito thyristor, kuti kuonetsetsa magwiridwe antchito apamwamba.

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 kuyeza kwa ukadaulo wa evaporation wa ma elekitironi kunagwiritsidwa ntchito popanga filimu yokhuthala ya aluminiyamu pamtunda wa silicon, ndipo wosanjikiza wa ruthenium wokutidwa pa molybdenum udzakulitsa kukana kutopa kwambiri, nthawi ya moyo wa thyristor idzawonjezeka kwambiri.

Kufotokozera zaukadaulo

1. Phase controlled thyristor yokhala ndi alloy type chip yopangidwa ndi RUNAU Electronics, osiyanasiyana I_{Mtengo wa TAV}kuchokera ku 300A mpaka 6000A ndi V_DRM/V_RRMkuchokera 800V mpaka 4400V.
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;
3. I²t=ine²F SM×tw/2,tw= Sinusoidal theka la mafunde apano m'lifupi.Pa 50Hz, I²t=0.005I²FSM(A²S);
4. pa 60Hz:I_{Mtengo wa FSM}(8.3ms)=ine_{Mtengo wa FSM}(10ms)×1.066,T_j=T_j;Ine²t(8.3ms)=ine²T(10ms)×0.943,T_j=T_jm
