Txoj cai ntawm switching fais fab mov
1. Thaum lub sij hawm ntawm lub hwj chim, tom qab lub teeb nyem ib pliag thiab tawm mus maj mam, lub hwj chim mov yog ib txwm los ntawm cov tswv yim mus rau rectification thiab filtering, thiab qhov txhaum yuav tsum nyob rau hauv lub rov qab Circuit Court. Txwv tsis pub, lub hwj chim fuse los yog lub input lim inductor qhib.
2. Yog hais tias lub rectifier thiab lim circuit yog ib txwm, xyuas seb puas muaj 310V voltage ntawm ob qho kawg ntawm lub raj hloov. Yog tias tsis yog, tus qauv resistor R0 los yog lub hauv paus ntawm lub transformer yog qhib.
3. Yog tias qhov hluav taws xob ntawm lub raj hloov hluav taws xob zoo li qub, xyuas seb qhov hloov hluav taws xob lub raj hluav taws xob puas muaj qhov hluav taws xob ntawm ob peb volts mus rau lub kaum os volts, yog tias tsis yog, xyuas qhov pib ua hauj lwm thiab lub voj voog tsav.
4. Yog hais tias tus tsav muaj hluav taws xob thiab lub raj hloov pauv yog qhov qub, qhov kev xav ntawm tus kheej yog qhov tsis raug lossis cov lus tawm tswv yim tsis raug.
5. Yog tias lub teeb pom kev ib txwm nyob, lub raj hloov pauv tau tawg (luv luv luv) lossis tus choj rectifier tawg (luv luv luv).
6. Yog hais tias lub teeb tig rau thiab tawm ib ntus, lub load muaj qhov cuam tshuam luv luv, thiab cov khoom tuaj yeem kuaj pom. Schematic daim duab ntawm switching zog mov qauv
7. Yog tias qhov hloov pauv hloov lub raj tawg rau ntau zaus, xyuas seb puas muaj qhov qhib Circuit Court txhaum nyob rau hauv lub ncov voltage tshem tawm Circuit Court thiab lub load.
8. Tom qab cov kauj ruam ntawm kev saib xyuas saum toj no thiab kuaj xyuas tias qhov load voltage yog qhov qub, hloov K tuaj yeem raug kaw. Yog tias qhov tso zis zoo li qub thaum kuaj xyuas dua, nws txhais tau hais tias cov khoom siv hluav taws xob hloov tau raug kho.
Lus Cim: Cov lus tawm tswv yim tsis zoo ntawm cov khoom siv hluav taws xob hloov pauv thiab qhov thib ob ntawm lub tshuab hloov pauv yuav tsum tsis txhob qhib, txwv tsis pub lwm qhov ntawm Circuit Court yuav puas.
