Xyoo 1955, tus kws tshawb fawb Asmeskas GHRoyer thawj zaug ua tiav ib qho transistor- rau -DC converter uas siv cov saturation ntawm cov hlau nplaum core los ua tus kheej -zoo siab oscillation. Txij thaum ntawd los, ntau hom DC converters siv cov thev naus laus zis no tau tshwm sim, uas tau hloov qhov kev siv thaum ntxov ntawm kev sib hloov thiab cov khoom siv oscillator commutation nrog lub neej luv luv, tsis muaj kev ntseeg siab, thiab kev hloov pauv tsis zoo. Vim hais tias lub hwj chim transistor nyob rau hauv lub transistor DC converter ua hauj lwm nyob rau hauv lub nyob rau hauv -tawm lub xeev, lub resulting tswj fais fab mov muaj ib tug loj tus naj npawb ntawm cov zis pawg, sib txawv polarity, high efficiency, me me thiab lub teeb yuag, yog li nws tau dav. siv lub sijhawm ntawd. Aerospace thiab tub rog cov khoom siv hluav taws xob. Vim lub backwardness ntawm microelectronic khoom thiab thev naus laus zis nyob rau lub sijhawm ntawd, transistors nrog siab tiv taus hluav taws xob, kev hloov pauv siab thiab lub zog siab tsis tuaj yeem tsim tawm, yog li DC converter nyob rau lub sijhawm no tsuas yog siv cov khoom siv hluav taws xob tsawg, thiab kev hloov pauv ceev tsis tau. siab. siab dhau lawm.
Txij li thaum xyoo 1960, vim muaj kev loj hlob sai ntawm microelectronics thev naus laus zis, transistors nrog siab rov qab voltage tau tshwm sim. Txij thaum ntawd los, DC converter tuaj yeem raug kho ncaj qha thiab lim los ntawm lub hauv paus, thiab lub zog zaus hloov pauv tsis tas yuav tsum tau nqis los, yog li txo qis kev siv hluav taws xob ntau. Nthuav nws daim ntawv thov ntau yam, thiab raws li qhov no, lub zog hloov pauv yam tsis muaj lub zog zaus theem -down transformer tau yug los. Lub hwj chim zaus transformer raug tshem tawm, thiab qhov ntim thiab qhov hnyav ntawm kev hloov hluav taws xob tswj hluav taws xob tau txo qis, thiab kev hloov hluav taws xob tswj hluav taws xob tuaj yeem ua tiav kev ua haujlwm siab, me me thiab lub teeb yuag.
Tom qab xyoo 1970, qhov siab - zaus thiab siab - rov qab -voltage fais fab transistors, siab - zaus capacitors, hloov diodes, hlau cores ntawm switching transformers thiab lwm yam khoom muaj feem xyuam. rau cov tshuab no kuj tau tsim thiab tsim tawm tsis tu ncua, yog li tsis muaj lub zog zaus transformer hloov hluav taws xob regulator. Cov khoom siv hluav taws xob tau tsim kho sai thiab siv dav hauv cov khoos phis tawj hluav taws xob, kev sib txuas lus, aerospace, xim TV thiab lwm yam, kom lub zog zaus transformer- pub dawb hloov hluav taws xob tau dhau los ua tus thawj coj ntawm ntau yam khoom siv hluav taws xob.
