Thyristor Tlhaloso

Litekanyetso tsa 1.IEC li ne li sebelisetsoa ho khetholla thyristor, ts'ebetso ea diode, e na le likarolo tse 'maloa tse leshome, empa basebelisi ba atisa ho sebelisa tse leshome kapa ho feta, sehlooho sena ka bokhutšoanyane thyristor / diode ea mekhahlelo e meholo.
2.Average Forward Current IF (AV) (rectifier) ​​/ Mean on-state current IT (AV) (Thyristor): e hlalosoa ho ea ka mocheso o tebang oa mocheso kapa mocheso oa TC THS ha o lumelloa ho phalla ka har'a halofo ea sine ea sesebelisoa. wave karolelano ea hona joale.Mothating ona, mocheso oa mateano o fihletse mocheso o phahameng o lumelletsoeng Tjm.Bukana ea Sehlahisoa sa LMH e fana ka boemo bo nepahetseng ba boemo ba hona joale bo tsamaellanang le thempereichara ea tekano ea mocheso THS kapa litekanyetso tsa mocheso oa TC, mosebelisi o lokela ho ipapisa le maemo a hona joale le maemo a mocheso ho khetha mofuta o nepahetseng oa sesebelisoa.
3.Forward motso bolela square jwale IF (RMS) (rectifier) ​​/ On-state RMS Current IT (RMS) (Thyristor): e hlalosoa ka ho ya ka mocheso sink mocheso kapa nyeoe mocheso TC THS ha e lumelloa ho phalla ka boholo ba sesebelisoa. boleng ba hona joale bo sebetsang.Ha e sebelisoa, mosebelisi o tla etsa bonnete ba hore maemong afe kapa afe, mocheso oa RMS o phallang ka har'a sesebelisoa ha o fete motso o lumellanang le boleng ba lisekoere tsa boleng ba hona joale.
4.Surge hona joale IFSM (rectifier), ITSM (SCR)
E emela ho sebetsa maemong a ikhethang, sesebelisoa se ka mamella maemo a hona joale a overload overload hang-hang.10ms half sine wave e nang le tlhoro eo LMH e fanoeng ka har'a bukana ea tlhahiso ea inrush boleng ba hajoale ke mocheso o phahameng o lumelletsoeng oa sesebelisoa o ka tlase ho 80% VRRM e sebelisitsoeng tlasa maemo a litekanyetso tsa tlhahlobo.Bophelong ba sesebelisoa ka mamella inrush hona joale e lekanyelitsoeng ke palo ya basebedisi ba a sebelisa lokela ho leka ho qoba overload.
5.Non repetitive peak off-state voltage VDSM / Non repetitive peak reverse voltage VRSM: e bua ka thyristor kapa rectifier diode e thibela boemo bo ka mamella matla a mangata a ho senya, hangata ka tlhahlobo ea pulse e le 'ngoe ho thibela tšenyo ea sesebelisoa.Mosebelisi tekong kapa ts'ebetsong, o tla thibeloa ho motlakase o sebelisoang ho sesebelisoa, ho qoba tšenyo ea sesebelisoa.
6.Peak e pheta-phetoang off-state voltage VDRM / Repetitive peak reverse voltage VRRM: e bolela hore sesebelisoa se boemong ba ho thibela, se-off-state le se ka morao se ka mamella matla a phahameng a ipheta-phetang.Ka kakaretso sesebelisoa ha se phete letšoao la motlakase oa 90% (lisebelisoa tse sa pheteheng tsa motlakase o phahameng li nka 100V e fokolang).Basebelisi ba sebelisoang ba tla etsa bonnete ba hore maemong afe kapa afe, ha baa lokela ho lumella sesebelisoa hore se mamelle motlakase oa nnete o feta boemo ba sona le Repetitive peak reverse voltage.
7.Peak e pheta-phetoang ho tloha boemong (ho lutla) IDRM ea hona joale / Repetitive peak reverse (leakage) IRRM ea joale
Thyristor e boemong ba ho thiba, ho mamella voltage e iphetang ea off-state VDRM le VRRM Repetitive peak reverse voltage, phallo e eang pele le e ka morao ka har'a karolo ea tlhoro ea metsi.Paramethara ena e lumella sesebelisoa ho sebetsa tlas'a mocheso o phahameng ka ho fetisisa oa Tjm o lekantsoeng.
8.Peak on-state voltage VTM (SCR) / Peak forward voltage VFM (rectifier)
E bua ka sesebelisoa ka tlhoro e reriloeng esale pele ea IFM (rectifier) ​​kapa boemo ba hona joale ba maemo a holimo ITM (SCR) ke peak voltage, e tsejoang hape ka hore ke peak voltage drop.Paramethara ena e bonts'a ka kotloloho litšobotsi tsa tahlehelo ea sesebelisoa maemong a mmuso, e amang boemo ba sesebelisoa se lekantsoeng hona joale.
Sesebelisoa se maemong a fapaneng a hona joale ka tlas'a matla a holimo (ho ea pele) se ka hakanyetsoa ka motlakase oa threshold le slope resistor, ho boletse:
VTM = VTO + rT * ITM VFM = VFO + rF * IFM
Matha k'hamphani ea Austria ka bukeng ea sehlahisoa bakeng sa mofuta o mong le o mong li fanoe ka matla a phahameng a sesebelisoa sa boemo (ho ea pele) le matla a matla a monyako le ho hanyetsa moepa, litlhoko tsa mosebelisi, o ka fana ka motlakase oa menyako ea sesebelisoa le moepa oa khanyetso e lekantsoeng. boleng.
9.Circuit commutated turn-time time tq (SCR)
Tlas'a maemo a boletsoeng, motlakase o ka sehloohong oa thyristor pele o theohela holim'a zero, ho tloha ho zero crossing ho khona ho mamella motlakase oa ntho e boima e sebelisoa ho e-na le ho fetola nako e fokolang ea nako.Nako ea nako ea ho tima ea Thyristor e khethoa bakeng sa maemo a teko, Run Austrian company e entsoeng ka potlako, lisebelisoa tse phahameng tsa maqhubu a thyristor li fana ka nako ea ho tima ea boleng bo bong le bo bong bo lekantsoeng, ha bo hlalosoe ka ho khetheha, maemo a lumellanang ke a latelang:
ITM-state tlhōrō ea hona joale e lekana le sesebelisoa sa ITAV;
Sekhahla sa ho fokotseha ha hona joale di / dt = -20A/μs;
Sekhahla se matla sa ho phahama ha motlakase dv / dt = 30A/μs;
Reverse voltage VR = 50V;
Mocheso oa mateano Tj = 125 ° C.
Haeba o hloka maemo a itseng a kopo ka boleng ba tlhahlobo ea nako e sa sebetseng, o ka kopa ho rona.
10. Sekhahla sa bohlokoa sa ho phahama ha on-state current di / dt (SCR)
E bua ka thyristor ho tloha ho thibela boemo ho ea ho mmuso, thyristor e ka mamella tekanyo e phahameng ea ho phahama ha boemo ba hona joale.Sesebelisoa se ka mamella boemo ba hona joale ba boemo bo Bohlokoa ba boemo ba ho phahama ha di / dt heke trigger ka tšusumetso e kholo, kahoo re khothaletsa ka matla hore basebelisi ba sebelise mochini oa ts'ebeliso, moferefere oa hona joale oa amplitude: IG ≥ 10IGT;nako ea ho phahama ha sekhahla: tr ≤ 1μs.
10. Sekhahla sa bohlokoa sa ho phahama ha motlakase oa off-state dv / dt
Tlas'a maemo a boletsoeng, e ke ke ea etsa hore thyristor e tlosoe mmuso ho ea sebakeng se fetolang lebelo le phahameng le lumellehang la ho phahama ha matla.Run Austria company product manual e fana ka mefuta e fokolang ea mefuta eohle ea thyristor dv / dt boleng, ha mosebedisi dv / dt a na le litlhoko tse khethehileng, a ka etsoa ha o laela.
11.Gate trigger voltage VGT / Gate trigger hona joale IGT
Tlas'a maemo a boletsoeng, ho etsa hore thyristor e tima boemo ka tekanyo e hlokahalang ea heke le heke ea hona joale.Thyristor e butsoe nakong ea lihora tsa ho bula, tahlehelo ea ho bula le ts'ebetso e 'ngoe e matla ka ho sebelisa matla a pontšo ea heke ea eona ka tšusumetso e kholo.Haeba ts'ebetsong ea IGT ea bohlokoa ho feta ho qala thyristor, thyristor e ke ke ea lumella ho fumana litšobotsi tse ntle tsa ho bula, maemong a mang esita le ho baka ho hlōleha pele ho nako kapa tšenyo ea sesebelisoa.Ka hona e khothalelitsoe hore sesebelisoa sa mosebelisi se sebelise mokhoa o matla oa trigger, trigger pulse current amplitude: IG ≥ 10IGT;nako ea ho phahama ha sekhahla: tr ≤ 1μs.Ho netefatsa ts'ebetso e tšepahalang ea sesebelisoa, IG e tlameha ho ba kholo ho feta IGT.
12.Crusts ho hanyetsa Rjc
E bua ka sesebelisoa tlas'a maemo a boletsoeng, sesebelisoa se phalla ho tloha mateanong ho ea ho phahama ha mocheso o hlahisoang ka watt.Khanyetso ea Crusts e bonahatsa matla a mocheso oa sesebelisoa, parameter ena e na le tšusumetso e tobileng ho ts'ebetso e lekantsoeng ea boemo ba sesebelisoa.Matha bukana ea sehlahisoa sa k'hamphani ea Austria bakeng sa sesebelisoa sa ho futhumatsa se nang le mahlakoreng a bataletseng se bonts'a ho hanyetsa mocheso o tsitsitseng oa li-module tsa matla a semiconductor, ho fana ka pholileng e lehlakoreng le le leng ho hanyetsa mocheso.Basebedisi ba lokela ho hlokomela hore karolo e bataletseng ea liphello karolong e ka holimo mogote angoa ka ho toba ke maemo a ho instola tse, feela ho ea ka bukana bakeng sa kgothaletswa ntseng bo eketseha matla tlhomamiso e le ho etsa bonnete ba ho hanyetsa mogote oa sesebediswa ho kopana le ditlhoko crusts.
