1.IEC miyero yakashandiswa kuratidza iyo thyristor, diode kuita, inoratidzira akati wandei gumi paramita, asi vashandisi vanowanzo shandisa gumi kana zvakadaro, chinyorwa ichi muchidimbu thyristor / diode yemaparamita makuru.
2.Average Forward Current IF (AV) (rectifier) ​​/ Mean on-state current IT (AV) (Thyristor): inotsanangurwa maererano nekupisa kunyura tembiricha kana tembiricha yekesi TC THS kana ichibvumidzwa kuyerera nepakati peiyo mudziyo wehafu sine. wave current average.Panguva ino, tembiricha yejunction yasvika pakupisa kwayo kunobvumidzwa Tjm.LMH Kambani Chigadzirwa Manual inopa yakakodzera nyika ikozvino inoenderana nekushisa kunyura tembiricha THS kana kesi tembiricha TC kukosha, mushandisi anofanirwa kunge ari pamusoro peiyo-yenyika ikozvino, uye mamiriro ekupisa kusarudza yakakodzera modhi yechishandiso.
3.Forward midzi inoreva square ikozvino IF (RMS) (rectifier) ​​/ On-state RMS Current IT (RMS) (Thyristor): inotsanangurwa maererano nekupisa kunyura tembiricha kana kesi tembiricha TC THS kana ichibvumidzwa kuyerera nepamusoro pechishandiso. inoshanda ikozvino kukosha.Mukushandisa, mushandisi anozoona kuti mune chero mamiriro, RMS ikozvino inoyerera kuburikidza nemudziyo kesi tembiricha haipfuure inoenderana mudzi inoreva square ikozvino kukosha.
4.Surge ikozvino IFSM (rectifier), ITSM (SCR)
Inomiririra kushanda mumamiriro ezvinhu akasarudzika, chishandiso chinogona kumirisana nekukasira kwakanyanyisa kuwandisa kwazvino kukosha.10ms hafu sine wave ine peak iyo LMH yakapihwa mune yechigadzirwa bhuku inrush yazvino kukosha ndiyo yakanyanya kutenderwa junction tembiricha yemudziyo iri pasi pe80% VRRM inoiswa pasi pemamiriro eiyo test value.Muhupenyu hwechigadzirwa chinogona kumira inrush ikozvino inogumira nehuwandu hwevashandisi vari kushandiswa vanofanira kuedza kudzivirira kuwandisa.
5.Non repetitive peak off-state voltage VDSM / Non repetitive peak reverse voltage VRSM: inoreva thyristor kana rectifier diode iri kuvharidzira nyika inogona kumira zvakanyanya breakover voltage, kazhinji ine imwechete pulse test kudzivirira kukanganisa kumudziyo.Mushandisi mukuyedza kana kushandisa, anozorambidzwa kune voltage inoiswa kune mudziyo, kudzivirira kukuvara kumudziyo.
6.Repetitive peak off-state voltage VDRM / Repetitive peak reverse voltage VRRM: zvinoreva kuti chigadziro chiri mumamiriro ekuvharira, iyo-off-state uye reverse inogona kumira yakawanda inodzokorora peak voltage.Kazhinji mudziyo haudzokorore voltage 90% mucherechedzo (isina-inodzokororwa voltage yakakwira voltage zvishandiso zvinotora mashoma akamakwa 100V).Vashandisi vari kushandiswa vanozoona kuti chero zvazvingava, havafanire kubvumira mudziyo kuti umire nemhepo chaiyo inodarika yayo off-state uye Repetitive peak reverse voltage.
7.Kudzokorora peak off-state (leakage) ikozvino IDRM / Repetitive peak reverse (leakage) ikozvino IRRM
Thyristor in blocking state, kushingirira kudzokorora peak off-state voltage VDRM uye VRRM Repetitive peak reverse voltage, kumberi nekudzokera kumashure kuyerera nepakati peak drain current.Iyi parameter inobvumira chishandiso kushanda pasi peiyo tembiricha yekusangana Tjm yakayerwa.
8.Peak on-state voltage VTM (SCR) / Peak mberi voltage VFM (rectifier)
Inoreva mudziyo neyakafanotemerwa kumberi peak ikozvino IFM (rectifier) ​​kana iyo peak ikozvino mamiriro ITM (SCR) ndiyo peak voltage, inozivikanwawo sepeak voltage kudonha.Iyi parameter inotaridza zvakananga hunhu hwechishandiso pa-nyika kurasikirwa, zvichikanganisa iyo mudziyo pa-state ikozvino yakayerwa kugona.
Chishandiso pamhando dzakasiyana dzazvino pasi pe-on-state (mberi) peak voltage inogona kufananidzwa neiyo threshold voltage uye slope resistor, akati:
VTM = VTO + rT * ITM VFM = VFO + rF * IFM
Mhanyai kambani yeAustria mugwaro rechigadzirwa chemodhi yega yega inopihwa muhukuru hwechishandiso pa-state (mberi) peak voltage uye chikumbaridzo voltage uye kutsetseka kuramba, mushandisi anoda, unogona kupa mudziyo wechikumbaridzo voltage uye kutsetseka kwekuyerwa kwekupokana. value.
9. Circuit yakachinja-chinja nguva tq (SCR)
Pasi pemamiriro akatsanangurwa, iyo huru ikozvino ye thyristor kumberi inodonha pamusoro zero, kubva pa zero kuyambuka kuti ikwanise kumirisana neinorema element voltage inoiswa pachinzvimbo chekushandura nguva shoma.Thyristor kudzima nguva kukosha kunotarirwa mamiriro ekuyedzwa, Mhanya Austrian kambani inogadzirwa nekukurumidza, yakakwirira-frequency thyristor zvishandiso zvinopa yekudzima nguva yeimwe neimwe yakayerwa kukosha, haina kunyanya kutsanangurwa, mamiriro anoenderana anotevera:
ITM-nyika yepamusoro peak ikozvino yakaenzana nemudziyo ITAV;
On-state ikozvino kuderera mwero di / dt = -20A/μs;
Inorema voltage kukwira mwero dv / dt = 30A/μs;
Reverse voltage VR = 50V;
Junction tembiricha Tj = 125 ° C.
Kana iwe uchida chaiyo application mamiriro mune off-time bvunzo kukosha, unogona kukumbira kwatiri.
10.Critical rate yekusimuka kwe-on-state ikozvino di / dt (SCR)
Inoreva iyo thyristor kubva pakuvhara nyika kuenda kune iyo nyika, iyo thyristor inogona kumira muyero wepamusoro wekukwira kwe-on-state ikozvino.Chishandiso chacho chinogona kumira pa-nyika ikozvino Yakakosha mwero wekusimuka di / dt gedhi rinokonzeresa mamiriro nekukanganisa kukuru, saka isu tinokurudzira zvakasimba kuti vashandisi vashandise iyo yekushandisa trigger, iyo inokonzeresa pulse ikozvino amplitude: IG ≥ 10IGT;nguva yekutsiga: tr ≤ 1μs.
10. Chiyero chakakosha chekukwira kwe-off-state voltage dv / dt
Pasi pemamiriro akatarwa, hazvizokonzerese kuti thyristor kubva kunze kwenyika kuenda kune iyo nyika kushandura iyo inotenderwa kumberi voltage kusimuka kumhanya.Run Austrian kambani chigadzirwa bhuku rinopa diki pane ese marudzi thyristor dv / dt kukosha, kana mushandisi dv / dt aine zvakakosha zvinodiwa, anogona kuitwa pakuhodha.
11.Gate trigger voltage VGT / Gedhi rinokonzera ikozvino IGT
Pasi pemamiriro akatsanangurwa, kuita iyo thyristor yekudzima mamiriro neinodiwa shoma gedhi voltage uye gedhi razvino.Thyristor yakavhurwa mukati memaawa ekuvhura, kurasikirwa kwekuvhura uye kumwe kuita kwakasimba nekushandisa mugedhi rayo inokonzeresa chiratidzo chesimba pane yakakura kukanganisa.Kana mukushandiswa kweiyo yakanyanya kunetsa IGT kukonzeresa thyristor, thyristor haizoregi kuwana yakanaka yekuvhura maitiro, mune dzimwe nguva inokonzeresa kutadza kumberi kana kukuvadzwa kwechishandiso.Saka yakakurudzira kuti mushandisi ashandise kushandisa yakasimba trigger mode, iyo inokonzeresa pulse ikozvino amplitude: IG ≥ 10IGT;nguva yekutsiga: tr ≤ 1μs.Kuti uve nechokwadi chekushanda kwakavimbika kwechigadzirwa, IG inofanira kunge yakakura kudarika IGT.
12.Crusts kuramba Rjc
Zvinoreva mudziyo pasi pemamiriro akatarwa, mudziyo uri kuyerera kubva pajunction kuenda kune tembiricha inokwira inogadzirwa pa watt.Crusts kuramba inoratidza kupisa kwechishandiso, iyi parameter ine yakananga kukanganiswa kwechigadzirwa-nyika yakatarwa kuita.Mhanyai Austrian kambani chigadzirwa bhuku re flat sided kutonhora mudziyo unoratidza yakatsiga-mamiriro ekupisa kwekushisa kweiyo semiconductor simba modules, inopa iyo imwe-sided kutonhora kupikisa kwemafuta.Vashandisi vanofanirwa kucherechedza kuti iyo yakatsetseka chikamu cheiyo crust thermal mhedzisiro yakanangana nemamiriro ekuisa, chete zvinoenderana negwaro reyakakurudzirwa yekumisikidza simba kuisirwa kuitira kuti ive nechokwadi chekupisa kwechishandiso kusangana nezvinodiwa crusts.
