Lub luag hauj lwm ntawm High Frequency Transformers nyob rau hauv Switching Fais Fab Khoom
Switching transformers muaj ntau yam zoo xws li kev hloov pauv siab, me me, lub teeb yuag, thiab kev ua haujlwm dav dav. Lawv yog siv rau hauv lub xov tooj ntawm tes chargers, roj teeb tsheb chargers, thiab ntau yam khoom siv hauv tsev. Yog li ntawd, hauv kev hloov cov khoom siv hluav taws xob, peb ib txwm pom lub tshuab hluav taws xob ntau zaus. Niaj hnub no, peb yuav tham txog nws lub luag haujlwm hauv kev hloov cov khoom siv hluav taws xob raws li qhov kev hloov pauv siab no.
Txoj haujlwm ua haujlwm ntawm kev hloov hluav taws xob
Muaj ob hom kev siv hluav taws xob hloov pauv: tus kheej zoo siab hloov cov khoom siv hluav taws xob thiab tus kheej zoo siab hloov hluav taws xob khoom siv. Tam sim no, cia peb coj tus kheej zoo siab hloov hluav taws xob ua piv txwv los piav qhia nws cov txheej txheem ua haujlwm, yog li peb tuaj yeem piav qhia ntxiv txog lub luag haujlwm ntawm cov tshuab hluav taws xob ntau zaus hauv kev hloov cov khoom siv hluav taws xob. Nyob rau hauv ib qho excitation switching fais fab mov, ib tug ywj siab oscillator generates ib tug tswj mem tes teeb liab los tswj cov conduction thiab disconnection ntawm hloov raj. Thaum lub raj hloov V yog nyob rau hauv lub xeev hloov, yuav muaj electromotive quab yuam generated nyob rau hauv thawj winding ntawm lub high-frequency transformer, uas yuav hnov nyob rau hauv lub thib ob winding. Lub electromotive quab yuam ntawm lub thib ob winding yog them los ntawm VD2 diode mus rau lub electrolytic capacitor, uas plays lub luag hauj lwm lim, Qhov no yuav tos rau ib tug ruaj khov DC voltage ntawm lub load RL.
Kev ua haujlwm ntawm High Frequency Transformers siv nyob rau hauv Hloov Cov Khoom Siv Hluav Taws Xob
Kuv xav tias high-frequency transformers muaj ob lub luag haujlwm tseem ceeb hauv kev hloov cov khoom siv hluav taws xob. Wb tham txog lawv cais. Thawj qhov taw tes yog tias siv cov tshuab hluav taws xob ntau zaus hauv kev hloov cov khoom siv hluav taws xob yog txhawm rau txhim kho kev hloov pauv ntawm cov khoom siv hluav taws xob. Vim yog siv cov silicon steel core ua cov tub ntxhais hlau ntawm high-frequency transformer, daim ntawv silicon steel no muaj cov hlau nplaum zoo heev, uas tuaj yeem txhim kho cov kev tiv thaiv thiab permeability, yog li txhim kho kev hloov pauv ntawm kev hloov hluav taws xob thiab ua kom nws cov khoom tso tawm. .
Lub ntsiab lus thib ob yog los tiv thaiv kev nyab xeeb ntawm kev thauj khoom thiab cov neeg ua haujlwm tom qab, ua si lub luag haujlwm ntawm kev nyab xeeb kev sib cais, thaum tseem ua kom huv lub zog hluav taws xob los tiv thaiv kev cuam tshuam. Peb xav tias qhov tso zis hluav taws xob ntawm cov khoom siv hluav taws xob hloov pauv siab dhau los vim qee qhov laj thawj thaum lub sijhawm ua haujlwm, thiab qhov hluav taws xob ntau dhau yuav raug xa mus rau qhov kev tiv thaiv Circuit Court. Kev tiv thaiv Circuit Court nyob rau hauv lub switching fais fab mov yuav qhib hom kev tiv thaiv, uas yuav "hais kom" lub hloov raj kom tsis txhob ua hauj lwm. Thaum lub raj hloov pauv tsis ua haujlwm, thawj winding kawg ntawm high-frequency transformer tsis tuaj yeem tsim hluav taws xob hluav taws xob, nyob rau hauv txoj kev no, qhov thib ob winding ntawm high-frequency transformer tsis tuaj yeem tau txais lub zog hluav taws xob induced, thiab tsis muaj qhov hluav taws xob tawm ntawm qhov tso zis kawg, yog li tiv thaiv lub load los ntawm high voltage puas. Yog tsis siv high-frequency transformers, qhov tshwm sim no yuav ua tau txaus ntshai heev. Yog tias lub raj hloov pauv tau tawg, qhov hluav taws xob siab yuav raug tso tawm ncaj qha rau cov khoom siv hluav taws xob, hluav taws xob hluav taws xob ncaj qha, thiab txawm tias muaj kev phom sij rau tib neeg txoj sia.
