Ikiraro cyibice bitatu bya thyristor ikosora birasabwa kugenzura moteri ya DC.Igikoresho gikwiye ningirakamaro kugirango hamenyekane imikorere ihamye yintangiriro yoroshye yo kugenzura moteri kandi igomba guhitamo guhuza numutungo wa moteri nibisabwa na sisitemu.Ihame ryo guhitamo ryatanzwe nkuko bikurikira:
1.Icyifuzo: kwinjiza voltage V.umurongo= 380V (3N 50Hz), ibisohoka DC ikigezweho I.d= 3600A, uburyo bwo gukonjesha bwa thyristor ni gukonjesha ikirere, ubushyuhe bwibidukikije T.A= 40 ℃, icyifuzo cyo kwiyongera cya I.TSM= 20KA.
2.Guhitamo voltage: agaciro k'umurongo wa voltage yagenwe
VD(max)= * V.I= * 380 = 537V, coefficente yo kurwanya ingaruka ifatwa nka 2.5, formula yo kubara igipimo cya voltage ni: VDSM37537V * 2.5 = 1343V, bityo
VDSM= V.RSM= 1400V.
3.Guhitamo ibyagezweho: bitewe nurutonde rwa thyristor iratandukanye hiyongereyeho amashanyarazi atandukanye, bityo rero tugomba kubara agaciro gakwiye kavuye muri thyristor hamwe na Vrrm = 1400V.I.d= 3600A, impuzandengo yikigereranyo inyura kuri buri thyristor I.T= 1200A, igipimo cyagenwe cya thyristor I.T (AV)= 1200A * 2.5 = 3000A.
4.Ubwo buryo bwo gukonjesha ikirere bizatoranywa ukurikije urutonde rwa thyristor.
5.Tristor na heatsink bigomba gutoranywa kubisabwa hamwe nibisabwa birambuye bya sisitemu yo kugenzura ibinyabiziga.Icyiciro cyo kugenzura thyristor na heatsink byakozwe na Jiangsu Yangjie Runau Semiconductor Co byahujwe cyane nuburyo bugezweho bwa tekinoroji yubuhanzi bwo gukora ibikoresho bikoresha ingufu za semiconductor.Irakoreshwa cyane muri porogaramu yo kugenzura ibinyabiziga.Nyamuneka saba abatekinisiye bacu babigize umwuga kugirango bahitemo ibikwiyethyristornaheatsinkkubikorwa byiza bya porogaramu yawe.
