Kwihlabathi elintsonkothileyo lezinto ze-elektroniki, uzinzo lwe-Igbts (i-Incherid I-Interrid bipolitors) njengelitye lendawo yokunyaniseka.Eli nqaku lidla intliziyo ye-pivonon ye-pivotan kwi-Igbs: isiphumo seLatch-up.Le mpembelelo iyonke intloko yayo xa imida iwela-ngqo, xa indawo yokusebenza ekhuselekileyo idlulile, ingenisa umlanjana wendlela yokubaleka yangoku.Iingcambu zale ndawo yenzekayo ayiloyisi kuphela nge-chip's uyilo kodwa kunye noyilo lwangaphakathi olungasebenziyo.Ngaphandle kokungathandeki okuphantsi kokusilela kwe-lanch-up kwi-PeAndoos ye-World-World Remandoos, ukubamba indlela yayo kuhlala kuyinto uyilo lwe-nuenced kunye nokusetyenziswa kwe-Igbs.
Masiqalise uhambo ngesakhiwo esisisiseko kunye nemigaqo yokusebenza ye-Igbt.Ukucocwa kweMosfET kunye neempawu ze-BJT, i-Igbt ivela njenge-semicondcuchouse.Iibhloko zayo ze-blueprint ezinxibelelana ne-bi-mos ye-bibytonUmdaniso wevolthi ngaphambili phakathi kwesango kunye ne-Emitter ivuselela i-mos tshisotor, ichitha indlela enyangekayo esezantsi kwisiseko se-PNP sothutho kunye nomqokeleli.Lo mthetho ubeka i-PNP ye-PNP.I-ploce chickens njengendawo ye-voltage ye-DWINGLES okanye ibuyise umva, icime i-Mos Tolisotor kunye nokufikelela kwisiseko se-PNP sothutho yangoku - ngenxa yoko, i-Igbt Dims.I-Igbts, ikhutshiwe ngenxa yolawulo lwevolthi, i-biquitious kumandla e-elektroniki.
Iziphumo ze-latch-up, i-culesty ebuhlungu yangaphakathi, ubuyela kwisekethe elinganayo ye-Igbt.Ifihliwe ngaphakathi kwezinto ezineparasitic, njengabafihlikiweyo.Iqokeleli egqithisileyo yangoku iphefumla ubomi buye kwala macandelo, kuphelise i-NPN TOTICT.Lo msitho ubeka phambili indlela yokusabela, ukugcwalisa zombini i-NPN kunye ne-PNP yothutho kunye nokuvusa i-quericic traksi kwi-conferitic kwi-lock-up.Le meko ye-canario uMqokeleli Okwangoku, ekhokelela kwi-malstrom yokusetyenziswa kwamandla kwaye, ekugqibeleni, isixhobo sokufa.
Ngaphaya kwendawo ye-static, impembelelo eguqukayo ye-Latch-up imiyalelo.Ngexesha lokujika okukhawulezayo, i-DV yangoku i-DV / DT Spawn i-Sheation okwangoku.Olu rhabaxa, ukuthuka ngokusebenzisa indawo yokwandiswa komzimba kwi-Rs, kunokukhuthaza i-NPN TOTISTOR.Yiyo loo nto ityhila i-saga yokuziva iguqukayo, yaphakamisa i-statter yokusilela kwesixhobo.
Ukuchasana nesiphumo se-latch-up, indlela eyahlukileyo yendlela.Eyona nto iphambili, kufuneka injini i-Igbt isebenza ngokunganyangekiyo kwezi mpembelelo, mhlawumbi ngokunciphisa i-RS.Emva koko, ukulawula i-PNP ye-PNP ye-HFA ngokubhekisele kwezolimo ze-N-Buffer Fleader kunye nenqanaba lokudlala libalulekile.Okokugqibela, sinokuyibeka i-HNP ye-PNP ye-PNP ye-HFE ineendlela zokunciphisa ubomi.
Ukuqukumbela, indawo ekhuselekileyo yokusebenza sisithende se-igbtt's Achilles 'Utyatyamba ngaphaya kwezinongoUkusuka ekufumaneni imveliso yokugqibela, inyathelo ngalinye kwi-Igbt Lewomveliso ye-Igbst ibaluleke kakhulu ekuvuneni izinto ze-notch, ezilungiselelwe iimfuno ezahlukeneyo.Ngokutyhila imityenzisi entsonkothileyo kwi-Igbts, sivula amandla okuphucula uyilo lwabo kunye nokusetyenziswa, inkqubo yenkqubo yokuxhomekeka kunye nokusebenza kakuhle.
