Intangiriro

Transformers zirashaje cyane.

Iyo ni yo myitwarire ya mbere abantu benshi bagira iyo bumvise "ikoranabuhanga rya transformer." N'ubundi kandi, induction ya electromagnetic yavumbuwe mu 1831. Uburyo bw'ibanze bwa transformer igezweho bwashyizweho mu 1885. Ni iyihe nkuru nshya igikoresho cy'imyaka 140 gishobora kuba cyaratanze?

Ariko ukuri ni ibinyuranye rwose. Ikoranabuhanga rya transformer ririmo guhinduka cyane kurusha ikindi kintu cyose mu myaka mirongo itanu ishize.

Imipaka itatu isobanura iyi mpinduka: transformateur za solid-state ziri kuva kuri "passive" zikajya kuri "active"; ibikoresho bya silicon carbide biri gutanga imbaraga muri iyi mpinduka; kandi ibikoresho by'icyatsi kibisi biri gutuma transformateur zikora neza kandi zitangiza ibidukikije. Kubiyobora ni ibintu bishya bisabwa n'impinduramatwara ya AI n'impinduka ku ngufu ku isi.

Iyi nkuru irakuganisha cyane muri izi mpaka eshatu, ihishura ahazaza h'ikoranabuhanga rya transformer.

Igice cya Mbere: Transformers za Solid-State—Kuva kuri "Iron Mass" kugeza kuri "Power Router"

1.1 Iherezo ry'Abahindura Ibintu Bisanzwe

Transformateur zisanzwe ni nziza kandi zifite aho zigarukira.

Mu buryo bworoshye bwazo, ni nziza cyane: icyuma cyo hagati hamwe n'imirongo y'umuringa, induction ya electromagnetic, nta bice bigenda, byizewe mu myaka ibarirwa muri za mirongo. Muri ubwo buryo bworoshye, zishobora guhindura voltage gusa mu buryo budakora. Ntizishobora kugenzura urujya n'uruza rw'amashanyarazi, ntizishobora gushyiraho imiraba, ntizishobora guhangana n'uruza rw'amazi mu cyerekezo kimwe, ntizishobora guhuza DC neza.

Mu gihe cy’imiyoboro y’amashanyarazi ikoresha icyerekezo kimwe n’imitwaro ihamye, iyi mipaka ntacyo yari ivuze. Ariko imiyoboro y’amashanyarazi y’iki gihe itandukanye cyane—ingufu z’izuba n’iz’umuyaga zirahindagurika cyane, imodoka zikoresha amashanyarazi zirasharira mu buryo butunguranye, ibigo by’amakuru bisaba ubusugire bukabije, kandi icyerekezo cy’amashanyarazi ntikiba gihamye. Imiterere y’imashini zisanzwe zihindura amashanyarazi irushaho kuba ingorabahizi.

1.2 Transformers zo mu rwego rwo hejuru: Gusobanura bundi bushya icyo Transformer ari cyo

Transformers za Solid-state (SSTs) zihindura burundu umukino.

Ihame ryabo ry’imikorere ritandukanye rwose n’iry’imashini zisanzwe zihindura amashanyarazi: icya mbere, ni ugukosora AC yinjira muri DC; hanyuma ugakoresha ikoranabuhanga rikoresha ingufu kugira ngo uhindure DC ibe AC ​​ifite frequency yo hejuru (hetz ibihumbi kugeza ku bihumbi amagana); unyuze muri transformer nto ifite frequency yo hejuru; hanyuma ukongera gukosora cyangwa gusubira inyuma ugana ku musaruro wifuza.

Ingano ya transfoma ingana cyane n'inshuro ikoreshwa—inshuro nyinshi bivuze ko igice cy'imbere gito. Transfoma ikenera ibiro amagana by'inkingi y'icyuma kuri 50 Hz ishobora gukenera gusa igice cy'imbere cy'icyuma kingana n'ikiganza kuri kilohertz nyinshi. Iryo ni ryo banga riri inyuma y'ubushobozi bwa SST bwogabanya ingano kugeza kuri 90%ugereranije n'ibishushanyo mbonera bisanzwe.

1.3 Intambwe y'Impinduka mu Kugera ku bushobozi bwo Gukora

Kugabanya ingano ni umusaruro ukurikira. Ikintu cy’ingenzi mu by’ukuri ni icyo SST zishobora gukora:

• Kugenzura neza ingufu z'amashanyarazi: umusaruro ukomeza kuba mwiza nubwo haba hari impinduka zidasanzwe mu buryo bw'ingufu
• Gushungura harmonic ikora: gutanga imiraba ya sine imeze neza cyane
• Imicungire y'ingufu mu cyerekezo kibiri: kwakira neza ikwirakwizwa ry'ibicuruzwa bikwirakwijwe
• Interineti ya DC itaziguye: amashami akoresha imirasire y'izuba, ububiko, n'amakuru ashobora guhuzwa mu buryo butaziguye
• Kwihutakwitandukanya n'amakosa: gusubiza mu masegonda make kugira ngo birinde ibikoresho biri inyuma y'amazi

Transformateur zisanzwe ni "ibice bidakora." SST ni "amanode akora." Zigaragaza uruhurirane rwinshi rw'ibikoresho by'ikoranabuhanga bikoresha ingufu n'ikoranabuhanga rikoresha transformateur - kuva ku "buremere bw'icyuma" kugera ku "rutayeri y'amashanyarazi".

1.4 Ishingiro ry'Ikigo cy'Amakuru cya AI

Porogaramu ya mbere ikomeye ituma SST ikoreshwa ni ikigo cy’amakuru cya AI.

Imitwaro y’imyitozo ya AI ifite umwihariko wayo: ihindagurika cyane mu masegonda make. Igihe kimwe, iba irimo gukora cyane; ikindi gihe, iba idakora. Uku guhinduka gukomeye gushimangira sisitemu z’amashanyarazi—voltage ishobora kugabanuka no kwiyongera, bigatuma seriveri iguma mu buryo ihagaze neza.

Transformateur zisanzwe nta cyo zikora. SST ntabwo zikora—zishobora gusubiza mu masegonda make, zigatuma umusaruro uhoraho kandi zigatuma seriveri ziguma mu buryo bwiza.

Icy'ingenzi kurushaho, ibigo by'amakuru birimo gukoresha uburyo bwa DC distribution. Seriveri zikorera imbere kuri DC. Uburyo busanzwe ni AC muri, gukosora kuri DC, hanyuma zigakwirakwiza—ibyiciro byinshi byo guhindura, ubushobozi buke, ubushyuhe bwinshi. SST zishobora gufata AC ifite voltage iri hagati mu buryo butaziguye zikanasohora DC ifite voltage iri hasi, zigakuraho ibyiciro byinshi nakunoza imikorere muri rusange ku kigero cya 3% cyangwa kirenga.

Ku kigo cy’amakuru cya hyperscale, iyo 3% bivuze miliyoni z’amadolari mu kuzigama amashanyarazi buri mwaka na toni ibihumbi mirongo mu kugabanya karuboni.

1.5 Ishusho y'isoko
