Electronic transformers ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob niaj hnub no. Raws li kev siv zaus, hluav taws xob transformers tuaj yeem muab faib ua cov tshuab hluav taws xob tsawg, nruab nrab zaus transformers thiab high-frequency transformers. Txhua ntu zaus ntawm transformers muaj nws tus kheej cov kev cai tshwj xeeb hauv kev tsim thiab kev tsim khoom, thiab ib qho tseem ceeb tshaj plaws yog cov khoom siv ntawm cov tub ntxhais. Kab lus no yuav tham txog qhov kev faib tawm zaus ntawm cov hluav taws xob transformers thiab lawv cov ntaub ntawv tseem ceeb.

Tsawg zaus transformers

Tsawg zaus transformers feem ntau yog siv nyob rau hauv lub hwj chim electronics nrog ib tug tsawg zaus ntau yam, feem ntau ua hauj lwm nyob rau hauv lub zaus ntawm 50 Hz mus rau 60 Hz. Cov transformers no tau siv dav hauv kev xa hluav taws xob thiab kev faib hluav taws xob, xws li hluav taws xob hloov hluav taws xob thiab kev sib cais transformers. Cov tub ntxhais ntawm lub tshuab hluav taws xob tsawg zaus feem ntau yog ua los ntawm silicon steel los xij, tseem hu ua silicon steel los xij.

Silicon hlau Sheetsyog ib hom khoom sib nqus mos uas muaj cov ntsiab lus silicon siab, muab cov hlau nplaum zoo permeability thiab tsis muaj hlau tsis zoo. Hauv kev siv tsawg zaus, kev siv cov ntaub ntawv silicon steel zoo txo ​​qhov poob ntawm qhov hloov pauv thiab txhim kho kev ua haujlwm. Tsis tas li ntawd, cov nplooj ntawv silicon steel muaj lub zog zoo txhua yam thiab kev tiv thaiv corrosion, ua kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob ua haujlwm ntev.

Mid-Frequency Transformers

Mid-frequency transformers feem ntau ua haujlwm nyob rau hauv ntau yam ntawm ob peb kilohertz (kHz) thiab feem ntau yog siv hauv cov khoom siv sib txuas lus, lub zog modules, thiab qee qhov kev tswj hwm kev lag luam. Cov cores ntawm nruab nrab zaus transformers feem ntau yog ua los ntawm amorphous magnetic cov ntaub ntawv.

Amorphous Magnetic Khoomyog cov hlau uas tsim los ntawm cov txheej txheem txias sai, ua rau muaj cov qauv amorphous atomic. Qhov tseem ceeb ntawm cov khoom siv no suav nrog cov hlau tsis tshua muaj hlau tsis tshua muaj thiab siab sib nqus permeability, muab kev ua tau zoo nyob rau hauv nruab nrab-ntau zaus. Kev siv cov khoom siv hlau nplaum amorphous zoo txo ​​qis zog hauv transformers thiab txhim kho kev hloov dua siab tshiab, ua rau lawv tsim tshwj xeeb rau cov ntawv thov uas xav tau kev ua haujlwm siab thiab poob qis.

High-Frequency Transformers

High-frequency transformers feem ntau ua haujlwm ntawm ntau zaus hauv megahertz (MHz) ntau lossis siab dua thiab siv dav hauv kev hloov cov khoom siv hluav taws xob, cov khoom siv sib txuas lus siab, thiab cov khoom siv cua sov siab. Cov cores ntawm high-frequency transformers feem ntau yog ua los ntawm PC40 ferrite khoom.

Tom ntej: PC40 Ferriteyog ib qho khoom siv high-frequency core nrog siab sib nqus permeability thiab qis hysteresis poob, muab kev ua tau zoo hauv kev siv ntau zaus. Lwm cov yam ntxwv tseem ceeb ntawm cov ntaub ntawv ferrite yog lawv cov hluav taws xob tiv thaiv siab, uas ua rau txo qis qhov poob tam sim no hauv cov tub ntxhais, yog li txhim kho kev ua haujlwm ntawm transformer. Qhov kev ua tau zoo tshaj ntawm PC40 ferrite ua rau nws yog qhov kev xaiv zoo tshaj plaws rau high-frequency transformers, ua tau raws li qhov xav tau ntawm kev ua haujlwm siab thiab tsis tshua muaj kev poob hauv cov ntawv thov siab.

Kev faib tawm zaus ntawm cov hluav taws xob hloov hluav taws xob thiab kev xaiv cov ntaub ntawv tseem ceeb yog qhov tseem ceeb cuam tshuam rau lawv cov kev ua tau zoo thiab kev siv ntau yam. Tsawg zaus transformers cia siab rau qhov zoo heev sib nqus permeability thiab txhua yam khoom ntawm silicon steel los xij, mid-frequency transformers siv cov yam ntxwv poob qis ntawm amorphous magnetic cov ntaub ntawv, thaum high-frequency transformers nyob ntawm siab magnetic permeability thiab tsis tshua muaj eddy tam sim no poob ntawm PC40. ferrite. Cov kev xaiv cov khoom no ua kom muaj kev ua haujlwm zoo ntawm cov khoom siv hluav taws xob thoob plaws ntau zaus thiab muab lub hauv paus ruaj khov rau kev ntseeg tau thiab kev ua tau zoo ntawm cov khoom siv hluav taws xob niaj hnub no.

Los ntawm kev nkag siab thiab paub txog qhov kev paub no, engineers tuaj yeem tsim tau zoo dua thiab txhim kho cov tshuab hluav taws xob kom ua tau raws li qhov xav tau ntawm ntau yam kev thov, txhawb kev nce qib thiab kev loj hlob ntawm cov khoom siv hluav taws xob.
