Lub luag hauj lwm ntawm high zaus transformer nyob rau hauv switching fais fab mov
Switching transformers muaj ntau yam zoo xws li kev hloov pauv siab, me me, lub teeb yuag, thiab kev ua haujlwm dav dav. Hloov cov khoom siv hluav taws xob yog siv rau hauv lub xov tooj ntawm tes chargers, roj teeb tsheb chargers, thiab ntau yam khoom siv hauv tsev. Hauv kev hloov cov khoom siv hluav taws xob, peb yuav tsum muaj lub tshuab hluav taws xob ntau zaus. Niaj hnub no peb yuav tham txog lub luag hauj lwm ntawm no high-frequency transformer nyob rau hauv switching fais fab mov.
Txoj haujlwm ua haujlwm ntawm kev hloov hluav taws xob
Peb paub tias muaj ob hom kev siv hluav taws xob hloov pauv: tus kheej zoo siab hloov hluav taws xob thiab lwm yam zoo siab hloov hluav taws xob. Tam sim no peb yuav siv cov piv txwv ntawm lwm qhov zoo siab hloov hluav taws xob los piav qhia nws cov txheej txheem ua haujlwm kom 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 lwm yam zoo siab switching fais fab mov, ib tug ywj siab oscillator generates ib tug tswj pulse teeb liab los tswj cov conduction thiab disconnection ntawm lub raj hloov. Thaum hloov lub raj V nyob rau hauv lub xeev hloov, yuav muaj ib tug electromotive quab yuam generated nyob rau hauv thawj winding ntawm lub high-frequency transformer. Yog li hais tias nws yuav raug ntxias mus rau qhov thib ob winding, lub zog hluav taws xob ntawm lub tshuab hluav taws xob thib ob yuav them cov hluav taws xob hluav taws xob los ntawm VD2 diode, thiab lub tshuab hluav taws xob electrolytic no yuav ua raws li cov lim dej, kom qhov ruaj khov DC voltage yuav tau txais ntawm lub load RL.
Lub luag hauj lwm ntawm high zaus transformers siv nyob rau hauv switching fais fab mov
Kuv xav tias lub high-frequency transformer feem ntau muaj ob txoj haujlwm hauv qab no hauv kev hloov hluav taws xob, thiab peb yuav tham txog lawv cais hauv qab no. Thawj qhov taw tes yog tias kev siv cov tshuab hluav taws xob ntau zaus hauv kev hloov cov khoom siv hluav taws xob yog los txhim kho kev hloov pauv ntawm cov khoom siv hluav taws xob. Txij li thaum cov tub ntxhais hlau ntawm lub siab zaus transformer yog silicon steel sheet hlau core, silicon steel daim ntawv no muaj cov hlau nplaum zoo permeability thiab tuaj yeem txhim kho qhov kev tiv thaiv thiab sib nqus permeability, yog li txhim kho kev hloov pauv ntawm kev hloov hluav taws xob thiab nce nws cov zis. . zog.
Lub ntsiab lus thib ob yog los tiv thaiv kev nyab xeeb ntawm kev thauj khoom tom qab thiab kev nyab xeeb ntawm tus kheej, uas ua lub luag haujlwm ntawm kev sib cais kev nyab xeeb, thiab 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 qhov hloov hluav taws xob hloov hluav taws xob siab dhau rau qee qhov laj thawj thaum lub sijhawm ua haujlwm, yog li cov hluav taws xob ntau dhau yuav raug xa mus rau qhov kev tiv thaiv Circuit Court, tom qab ntawd kev tiv thaiv Circuit Court nyob rau hauv lub zog hloov hluav taws xob yuav tig rau hom kev tiv thaiv, thiab Nws yuav "hais kom" hloov Thaum lub raj hloov pauv tsis ua haujlwm, thawj winding kawg ntawm high-frequency transformer tsis tuaj yeem tsim hluav taws xob quab yuam, yog li qhov thib ob winding ntawm high-frequency transformer tsis tuaj yeem tau txais lub zog hluav taws xob, thiab cov khoom siv hluav taws xob. yuav tsis muaj hluav taws xob tso zis, yog li tiv thaiv lub load yog tiv thaiv los ntawm high voltage puas. Yog tias tsis siv lub tshuab hluav taws xob ntau zaus, thaum qhov tshwm sim no tshwm sim, nws yuav txaus ntshai heev. Yog tias lub raj hloov pauv tau tawg, qhov hluav taws xob siab yuav raug tso tawm ncaj qha rau ntawm cov khoom siv hluav taws xob, uas yuav ncaj qha hlawv cov khoom siv hluav taws xob, thiab txawm tias muaj kev phom sij rau tib neeg lub neej.
