Buundada hagaajinta thyristor saddex waji ah ayaa loo baahan yahay si loo xakameeyo matoorka DC.Qalabka ku habboon ayaa muhiim u ah in la hubiyo hawlgalka xasilloon ee bilawga jilicsan si loo xakameeyo mootada waana in la doortaa si ay ula mid noqoto hantida matoorka iyo shuruudaha nidaamka.Mabda'a xulashada ayaa lagu qeexay sida soo socota:
1.Condition: danab gelin Vline= 380V (3N 50Hz), wax soo saarka DC hadda Id= 3600A, habka qaboojinta ee thyristor waa qaboojinta hawada, heerkulka deegaanka TA= 40 ℃, qulqulka qulqulka la rabo ITSM=20KA.
2.Selection of danab: qiimaha ugu sarreeya ee danab line lagu qiimeeyay
VD(max)=*VI= * 380=537V, isbahaysiga kahortaga saamaynta waxaa loo tixgalinayaa 2.5, qaacidada lagu xisaabiyo darajada danabku waa: VDSM≥537V*2.5= 1343V, sidaas darteed
VDSM= VRSM= 1400V.
3.Selection of current: sababtoo ah dulucda thyristor way ka duwan tahay marka lagu daro hadda kala duwan, markaa waa in aan ka xisaabinnaa qiimaha ku haboon ee thyristor Vrrm=1400V.Id= 3600A, celceliska hadda socda wuxuu maraa thyristor kasta IT= 1200A, hadda la qiimeeyay ee thyristor IT (AV)=1200A*2.5=3000A.
4. Sida kuleyliyaha qaboojinta hawada waxaa lagu dooran doonaa iyadoo loo eegayo dulucda thyristor.
5.Tyristor iyo heatsink waa in lagu doortaa ka soo horjeeda codsiga iyo shuruudaha faahfaahsan ee nidaamka xakamaynta mootada.Xakamaynta wajiga thyristor iyo heatsink oo ay soo saartay Jiangsu Yangjie Runau Semiconductor Co ayaa si heer sare ah ugu dhex milmay gobolka tignoolajiyada farshaxanka ee soo saarista aaladda awooda sare ee semiconductor.Waxa si weyn loogu isticmaalaa codsiga xakamaynta gudbinta mootada.Fadlan la xidhiidh farsamoyaqaannadayada xirfadlayaasha ah si aad u dooratid kuwa ku habboonthyristoriyokululayntaWaxqabadka ugu wanaagsan ee codsigaaga.
