Lub tswvyim ntawm transformer tau tshwm sim tom qab kev tshawb pom ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction nyob rau hauv lub xyoo pua puv 19. Nyob rau hauv 1831, Michael Faraday nrhiav tau electromagnetic induction, nteg lub theoretical foundation rau yav tom ntej hwj chim hloov khoom siv. Los ntawm 1880s, engineers pib sim nrog voltage transformation siv alternating tam sim no (AC) los daws cov teeb meem tsis muaj zog cuam tshuam nrog ntev -siv fais fab kis. Cov khoom siv thaum ntxov muaj cov qauv yooj yim- feem ntau nrog qhib sib nqus hluav taws xob- thiab kev ua haujlwm qis, tab sis lawv tau pom tias muaj peev xwm txhim kho kev sib kis tau zoo los ntawm kev hloov pauv qib voltage.
Lub sijhawm dhau los ntawm lig 19th thiab thaum ntxov 20th centuries cim ib theem ntawm kev loj hlob sai sai rau transformers. Raws li AC cov tshuab maj mam hloov pauv cov kab hluav taws xob ncaj qha (DC), cov tshuab hloov pauv tau los ua ib qho tseem ceeb ntawm cov phiaj xwm hluav taws xob. Hungarian engineers-xws li Déri, Bláthy, thiab Zipernowsky- tau ua lub luag haujlwm tseem ceeb hauv kev tsim cov kaw - cov tub ntxhais hloov pauv, uas ua rau muaj txiaj ntsig zoo thiab ua rau kev lag luam thov. Tom qab ntawd, cov tuam txhab xws li Westinghouse tau tsav cov txheej txheem ntawm cov tshuab hluav taws xob, ua rau muaj kev hloov pauv thoob plaws hauv kev tsim hluav taws xob, kev sib kis, thiab kev sib txuas.
Thoob plaws hauv lub xyoo pua 20th, transformer thev naus laus zis txuas ntxiv kom paub tab thiab ua kom zoo dua. Kev txais yuav ntawm silicon steel cores txo qis eddy - tam sim no poob, thaum roj - raus txias txias tshuab txhim kho kev ua haujlwm ruaj khov rau siab - muaj peev xwm units. Tsav los ntawm kev xav tau hluav taws xob nce ntxiv, kev txhim kho ntxiv -high voltage (EHV) thiab ultra-high voltage (UHV) technologies ua ntev - nrug, siab - muaj peev xwm xa hluav taws xob tau. Niaj hnub nimno transformers tseem pom kev txhim kho hauv cov ntaub ntawv, rwb thaiv tsev, thiab cov qauv tsim, thaum tib lub sijhawm hloov mus rau kev ua tau zoo dua, kev poob qis, thiab kev saib xyuas ntse.
