1.IEC ngenderwaho yakoreshejwe mu kuranga thyristor, imikorere ya diode, igaragaramo ibipimo icumi, ariko abakoresha akenshi bakoresha icumi cyangwa irenga, iyi ngingo muri make thyristor / diode yibipimo nyamukuru.
2.Gereranya Imbere Yimbere NIBA (AV) (ikosora) / Bivuze kuri leta ya IT (AV) (Thyristor): isobanurwa ukurikije ubushyuhe bwa sink ubushyuhe cyangwa ubushyuhe bwikibazo TC THS mugihe yemerewe kunyura mugice kinini cya sine impuzandengo.Kuri iyi ngingo, ubushyuhe bwihuza bwageze ku bushyuhe ntarengwa bwemewe Tjm.Igitabo cyibicuruzwa bya LMH gitanga leta ikwiranye nubushyuhe bwa sink ubushyuhe THS cyangwa ubushyuhe bwikigereranyo TC indangagaciro, uyikoresha agomba kuba ashingiye kumiterere nyayo kuri leta, hamwe nubushyuhe bwumuriro kugirango ahitemo icyitegererezo cyibikoresho.
3.Imizi yimbere isobanura kwaduka kweri NIBA (RMS) (ikosora) / Kuri leta ya RMS IT IT (RMS) (Thyristor): isobanurwa ukurikije ubushyuhe bwa sink ubushyuhe cyangwa ubushyuhe bwikibazo TC THS mugihe yemerewe gutembera mubikoresho byinshi agaciro keza.Mugukoresha, uyikoresha agomba kwemeza ko mubihe byose, imiyoboro ya RMS inyura mubikoresho byubushyuhe ntibishobora kurenza imizi ihwanye na kare kare agaciro.
4.Gukurikirana IFSM y'ubu (ikosora), ITSM (SCR)
Abahagarariye bakora mubihe bidasanzwe, igikoresho kirashobora kwihanganira ako kanya kurenza urugero agaciro karenze.10ms igice cya sine wave hamwe nimpinga LMH itangwa mubicuruzwa byintoki inrush agaciro kayo nigipimo ntarengwa cyemewe cyo guhuza igikoresho kiri munsi ya 80% VRRM ikoreshwa mugihe cyibiciro byagaciro.Mubuzima bwigikoresho gishobora kwihanganira inrush igarukira kumubare wabakoresha bakoresha bagomba kugerageza kwirinda kurenza urugero.
5.Nta mpinga isubirwamo ya voltage ya leta VDSM / Ntisubiramo impagarike ya voltage VRSM: bivuga thyristor cyangwa rectifier diode ihagarika leta irashobora kwihanganira voltage ntarengwa yamenetse, mubisanzwe hamwe no gupima impanuka imwe kugirango wirinde kwangiza igikoresho.Umukoresha mugupima cyangwa gusaba, birabujijwe kuri voltage ikoreshwa kubikoresho, kugirango wirinde kwangiza igikoresho.
6.Isubiramo ryinshi rya reta ya leta ya VDRM / Gusubiramo impagarike ihindagurika ya voltage VRRM: bivuze ko igikoresho kiri mukubuza leta, reta-reta na revers irashobora kwihanganira voltage ntarengwa isubirwamo.Mubisanzwe igikoresho ntigisubiramo voltage ya 90% (ibikoresho bidasubirwaho na voltage ibikoresho bya voltage bifata bike 100V).Abakoresha mukoresha bagomba kwemeza ko uko byagenda kose, ntibagomba kwemerera igikoresho kwihanganira voltage nyirizina irenze iyo itari iy'igihugu kandi isubiramo impanuka ya voltage.
7.Impera zisubiramo zitari muri leta (kumeneka) IDRM y'ubu / Gusubiramo impinga ihindagurika (kumeneka) IRRM y'ubu
Thyristor muguhagarika leta, kugirango ihangane nimpanuka zisubirwamo zumubyigano wa VDRM na VRRM Gusubiramo impagarike yibisubizo byumuvuduko, imbere no guhindukira unyuze mubice bigize imiyoboro y'amazi.Iyi parameter yemerera igikoresho gukora munsi yubushyuhe ntarengwa bwa Tjm yapimwe.
8.Kora kuri leta ya voltage VTM (SCR) / Impinga yimbere ya voltage VFM (ikosora)
Yerekeza ku gikoresho cyateganijwe mbere yimpera yimbere ya IFM (ikosora) cyangwa impanuka ya reta ya ITM (SCR) ni voltage yumuriro, bizwi kandi ko impanuka ya voltage yamanuka.Iyi parameter irerekana mu buryo butaziguye ibiranga igikoresho ku gihombo cya leta, bigira ingaruka ku gikoresho kiri kuri leta igezweho.
Igikoresho ku ndangagaciro zitandukanye ziri munsi ya leta (imbere) ya voltage yumuriro irashobora kugereranywa na voltage yumutambiko hamwe na résistoriste, ati:
VTM = VTO + rT * ITM VFM = VFO + rF * IFM
Koresha isosiyete yo muri Otirishiya mu gitabo cy’ibicuruzwa kuri buri cyitegererezo gitangwa mu gipimo ntarengwa cy’ibikoresho kuri leta (imbere) hejuru y’umubyigano wa voltage hamwe n’umubyigano w’umubyigano hamwe n’umuvuduko ukabije, umukoresha arakeneye, urashobora gutanga igikoresho cy’ibikoresho byinjira n’umurongo w’ibipimo byapimwe agaciro.
9.Umuzunguruko wagabanijwe kuzimya igihe tq (SCR)
Mubihe byagenwe, ibyingenzi byingenzi bya thyristor bigabanuka hejuru ya zeru, kuva kuri zeru kwambuka kugirango ubashe kwihanganira ibintu biremereye voltage ikoreshwa aho kugirango uhindure igihe ntarengwa.Igihe cya Thyristor cyo kuzimya igihe cyagenwe kugirango ibizamini bishoboke, Run Company yo muri Otirishiya yakoze ibikoresho byihuse, byihuta cyane bya thyristor itanga igihe cyo kuzimya kuri buri gipimo cyapimwe, ntabwo bisobanuwe cyane, imiterere ijyanye niyi ikurikira:
Imiyoboro ya ITM-leta ihwanye nigikoresho ITAV;
Kuri leta igabanuka igipimo di / dt = -20A / μs;
Umuvuduko mwinshi wa voltage dv / dt = 30A / μs;
Guhindura voltage VR = 50V;
Ubushyuhe bwo guhuza Tj = 125 ° C.
Niba ukeneye ibisabwa byihariye mubisabwa mugihe cyigihe cyo kugerageza, urashobora kudusaba.
10.Igipimo gikomeye cyo kuzamuka kwa leta iriho di / dt (SCR)
Yerekeza kuri thyristor kubuza leta kugera kuri leta, thyristor irashobora kwihanganira igipimo ntarengwa cyo kuzamuka kwa leta.Igikoresho kirashobora kwihanganira kuri leta iriho Igipimo gikomeye cyo kuzamuka di / dt amarembo yimiterere ningaruka zikomeye, turasaba rero cyane ko abakoresha bakoresha imbarutso ya progaramu, imbarutso ya pulse ya amplitude: IG ≥ 10IGT;igihe cyo kuzamuka kwa pulse: tr ≤ 1μs.
10. Igipimo gikomeye cyo kuzamuka kwumubyigano wa leta dv / dt
Mubihe byagenwe, ntabwo bizatera thyristor kuva kuri reta kugeza kuri leta ihindura byinshi byemewe byihuta byihuta byihuta.Koresha igitabo cyibicuruzwa byamasosiyete yo muri Otirishiya bitanga umuto wubwoko bwose thyristor dv / dt agaciro, mugihe umukoresha dv / dt afite ibisabwa byihariye, birashobora gukorwa mugihe utumije.
11.Irembo ritera voltage VGT / Irembo ritera IGT iriho
Mubihe byagenwe, kugirango thyristor izimya leta kubisabwa byibuze byibuze byinjira mumarembo.Thyristor yafunguye mumasaha yo gufungura, gufungura igihombo nibindi bikorwa bikora ukoresheje amarembo yayo yerekana imbaraga imbaraga zikomeye.Niba mugukoresha IGT ikomeye cyane kugirango itere thyristor, thyristor ntizemera ko ibona ibintu byiza byo gufungura, mubihe bimwe na bimwe bitera kunanirwa imburagihe cyangwa kwangiza igikoresho.Niyo mpamvu wasabye ko ukoresha porogaramu ukoresheje uburyo bukomeye bwa trigger, imbarutso ya pulse ya amplitude: IG ≥ 10IGT;igihe cyo kuzamuka kwa pulse: tr ≤ 1μs.Kugirango umenye neza imikorere yigikoresho, IG igomba kuba nini kuruta IGT.
12.Yizere kurwanya Rjc
Yerekeza ku gikoresho mu bihe byagenwe, igikoresho kiva mu masangano kigana ubushyuhe bwiyongera kuri watt.Kurwanya Crusts byerekana ubushobozi bwubushyuhe bwigikoresho, iyi parameter igira ingaruka itaziguye kumikorere ya leta yagenwe.Koresha igitabo cyibicuruzwa bya sosiyete yo muri Otirishiya kubikoresho bikonjesha bikonje byerekana uburyo buhoraho bwo guhangana nubushyuhe bwumuriro wa semiconductor power modules, butanga uruhande rumwe rukonjesha ubushyuhe bwumuriro.Abakoresha bagomba kumenya ko igice kibase cyingaruka ziterwa nubushyuhe bwatewe nuburyo bwo kwishyiriraho, gusa ukurikije imfashanyigisho yo gushiraho ingufu zashyizweho kugirango harebwe niba ubushyuhe bwumuriro bwibikoresho byujuje ibisabwa.
