Imbaraga Zirenze IGBT Aluminium Ubushyuhe

Umugenzuzi wa moteri Yakinguye Irembo rya Bipolar Transistor (Isohora Irembo Bipolar Transistor, IGBT) imikorere yo gukwirakwiza ubushyuhe iragenda iba moteri IGBT ubu yinjira mumasoko yingufu za elegitoroniki yinganda, nka (gusudira) ubushyuhe, imashini ikurura, moteri, nibindi.Ruiqifengitanga IGBT yubushyuhe bwo guteranya ibicuruzwa byemerera IGBT gukorera hejuru yubushyuhe bwo hejuru mugihe ubushyuhe bwakazi bukora murwego rwumutekano mukomatanya kurwanya ubushyuhe buke hamwe na silicon ya Vce (kuri).

IGBT mubihe byinshi ikorana nigikoresho kinini cyingufu, ingufu nyinshi bivuze ko ubushyuhe bukabije, IGBT ireba ubushobozi bunini, inshuro nyinshi, byoroshye gutwara, igihombo gito, modular, yerekana icyerekezo cyiterambere, ugereranije nibindi bikoresho bya elegitoroniki, Ubushyuhe bwa IGBT bufite ubwizerwe buhanitse, disiki yoroshye, byoroshye kurinda, nta muyoboro wa buffer uhari kandi guhinduranya inshuro ni ndende, bityo ubushyuhe bwa IGBT ku isoko rya elegitoronike biba ngombwa cyane.Kugirango ugere kuri ibyo bikorwa bihanitse, inzira nyinshi zikoreshwa mumuzunguruko uhuriweho, nka epitaxy, implantation ion, lithographie nziza, nibindi. Mu myaka yashize, imikorere yimbaraga za IGBT module yubushyuhe bwazamutse vuba, ibipimo byagenwe bifite yageze ku magana amperes, kwihanganira voltage irenga 1500V, kandi iracyatera imbere.Kubera ko ibikoresho bya IGBT bifite ibimenyetso byiza biranga diode ya PIN, ibiranga ingufu za p-umuyoboro wa IGBT module yubushyuhe ntibitandukanye cyane nubwa n-umuyoboro wa IGBT, bifasha cyane gufata imiterere yuzuzanya muri porogaramu, bityo ikaguka ikoreshwa ryayo murwego rwa ac na tekinoroji yo kugenzura.Inyungu nini ya IGBT nuko ishobora kwihanganira ihungabana ryubu haba kumurongo cyangwa mugufi.Ihuza ryayo ntago ari ikibazo kandi guhuza kwayo biroroshye kubera gutinda kwayo gutinze.

Uburyo bwo kohereza ubushyuhe bwa IGBT mubusanzwe burimo gukonjesha ikirere, gukonjesha amazi, ubushyuhe bwumuringa cyangwa ubushyuhe bwa aluminium.Ubushuhe bwayo bushingiye ku ihame shingiro ryo guhererekanya ubushyuhe, inzira itemba yubushyuhe hamwe nubushyuhe buke bwo kurwanya ubushyuhe bwateguwe kubikoresho kugirango ubushyuhe butangwa nigikoresho bushobora gusohoka vuba bishoboka, kugirango harebwe niba imbere ubushyuhe bwubushyuhe bwibikoresho burigihe bugumishwa mubushuhe bwemewe.

Kugeza ubu, ubushyuhe bwa IGBT busanzwe bushyirwa mu isoko cyane cyane burimo gukwirakwiza ubushyuhe, imiyoboro yubushyuhe hamwe na substrate, kuri substrate ihabwa ibice byinshi bifitanye isano, hanyuma igikoni kikaba gisudira hamwe nuwagurishije kugeza igice cyuka cya umuyoboro w'ubushyuhe.Muri tekinoroji ya IGBT yubushyuhe bwa tekiniki yubushyuhe, igice cyo guhumeka cyumuyaga ushyinguwe mumashanyarazi ya substrate kandi ntabwo gihuye neza nubuso bwa IGBT.Mubikorwa byakazi, ubushyuhe buva hejuru ya IGBT bwoherezwa hanze binyuze muri substrate hanyuma bukoherezwa kumuyoboro wubushyuhe hamwe nubushyuhe.Ubwanyuma, ubushyuhe buva mubushyuhe bwimurirwa mu kirere na convection.Kuberako substrate ubwayo ifite imbaraga zo kurwanya ubushyuhe, kandi coefficente yubushyuhe bwumuriro wa pipe yubushyuhe irarenze cyane iy'ibanze, imikorere yubushyuhe bwumuriro wa pisine yubushyuhe iragabanuka, kandi imikorere yo gukwirakwiza ubushyuhe iragabanuka.Ubushyuhe bwa IGBT burashobora kwimura ubushyuhe buringaniye kuva muri substrate kugeza kuri fin, bushobora gukemura neza ikibazo cyo gukwirakwiza ubushyuhe bwumuriro mwinshi, atari hamwe gusa nubushobozi buhanitse ariko nanone hamwe nuburyo bworoshye kandi nta bice byimuka, bishobora rwose kumenya kubungabunga- ubuntu.
