Ho hlokahala borokho ba mekhahlelo e meraro ea thyristor ho laola motlakase oa DC.Sesebelisoa se loketseng ke sa bohlokoa ho etsa bonnete ba ts'ebetso e tsitsitseng ea starter e bonolo ho laola motlakase mme e tlameha ho khethoa ho lumellana le thepa ea motlakase le tlhokahalo ea tsamaiso.Molao-motheo oa khetho o fanoa ka tlase:
1. Boemo: motlakase oa ho kenya Vmola=380V (3N 50Hz), tlhahiso ea DC ea hajoale Id=3600A, mokhoa o pholileng oa thyristor ke pholile ea moea, mocheso oa tikoloho TA=40 ℃, surge e lakatsehang hona joale ITSM=20KA.
2.Khetho ea motlakase: boleng ba tlhōrō ea motlakase oa mohala o lekantsoeng
VD(max)=*VI=*380=537V, coefficient e khahlanong le tšusumetso e nkoa e le 2.5, mokhoa oa ho bala boemo ba motlakase ke: V.DSM≥537V * 2.5 = 1343V, kahoo
VDSM= VRSM= 1400V.
3.Khetho ea hona joale: ka lebaka la kemiso ea thyristor e fapane ho phaella ho mefuta e fapaneng ea hona joale, kahoo re lokela ho bala boleng ba hona joale bo loketseng ho tloha thyristor le Vrrm = 1400V.Id=3600A, karolelano ea hajoale e feta ho thyristor IT=1200A, nako e lekantsoeng ea thyristor IT(AV)=1200A*2.5=3000A.
4.Moea o joalo o futhumatsang heatsink o tla khethoa ho latela kemiso ea thyristor.
5.The thyristor le heatsink li lokela ho khethoa khahlanong le kopo le litlhoko tse qaqileng tsa tsamaiso ea likoloi.The phase control thyristor le heatsink e entsoeng ke Jiangsu Yangjie Runau Semiconductor Co e kopantsoe haholo le boemo ba theknoloji ea theknoloji ea ho etsa lisebelisoa tse phahameng tsa semiconductor.E sebelisoa haholo ts'ebetsong ea taolo ea phetisetso ea enjene.Ka kopo ikopanye le litsebi tsa rona tsa litsebi ho khetha tse loketsengthyristorleho oela ha mochesobakeng sa ts'ebetso e ntle ka ho fetisisa ea kopo ea hau.
