Cov keeb kwm kev loj hlob ntawm transformers tuaj yeem taug qab mus rau thaum ntxov xyoo pua 19th. Qee qhov kev sim ua ntej lub cev muaj zog tau pom tias tam sim no tuaj yeem hloov mus rau hauv qhov hluav taws xob hauv qab electromagnetic induction. Lub tswv yim no tau muab tso rau los ntawm tus kws tshawb fawb Askiv Askiv Michael Faraday hauv xyoo 1831. Nyob rau xyoo tom ntej no, ntau tus kws tshawb fawb thiab cov kws tshaj lij tau tshawb fawb thiab txhim kho electromagnetic induction technology.
Nyob rau hauv 1885, Italian physicist Rudolf Jurabioni tau tsim thawj lub tswv yim transformer. Lub tshuab hluav taws xob no tuaj yeem hloov pauv tam sim no rau hauv qhov sib txawv ntawm qhov sib txawv thiab cov khoom siv hluav taws xob, ua rau nws muaj txiaj ntsig zoo hauv kev xa hluav taws xob ntau dua. Qhov kev tsim kho no ua rau kev xa hluav taws xob ua tau thiab tuaj yeem ua rau muaj kev hloov pauv nyiaj txiag thiab kev sib raug zoo.
Nyob rau hauv thaum ntxov 20th caug xyoo, ntau yam kev siv ntawm transformers pib nthuav, nrog rau kev sib txuas lus, induction cookers, thiab lub zog cia technology. Nyob rau xyoo 1950, cov tshuab hluav taws xob microelectronics tshwm sim ua rau kev txhim kho ntawm cov tshuab hloov pauv sai dua. Niaj hnub nimno transformers feem ntau yog ua los ntawm silicon, uas muaj ntau dua efficiency thiab me me ntim.
Zuag qhia tag nrho, txoj kev loj hlob ntawm transformers tau nrog kev vam meej nyob rau hauv lub tshav pob ntawm hluav taws xob engineering. Los ntawm kev tshawb fawb theoretical thaum ntxov mus rau niaj hnub siv tau zoo thiab txuag hluav taws xob, transformers, raws li classic electromagnetic induction thev naus laus zis, tau ua tiav kev vam meej thiab kev loj hlob.
