Hloov fais fab mov yog ib hom khoom siv hluav taws xob uas siv hluav taws xob niaj hnub siv hluav taws xob los tswj lub sijhawm sib piv ntawm kev hloov mus rau thiab tawm hauv lub sijhawm kom tswj tau qhov tso tawm hluav taws xob ruaj khov.Hloov cov khoom siv hluav taws xob feem ntau yog tsim los ntawm pulse width modulation (PWM) tswj ICs thiab MOSFET.Nrog rau txoj kev loj hlob thiab kev tsim kho tshiab ntawm lub zog hluav taws xob tshuab hluav taws xob, kev siv hluav taws xob hloov hluav taws xob thev naus laus zis kuj tseem niaj hnub tsim kho tshiab.Tam sim no, cov khoom siv hluav taws xob hloov pauv tau siv dav hauv yuav luag txhua yam khoom siv hluav taws xob vim nws qhov me me, lub teeb yuag thiab kev ua haujlwm siab.Nws yog ib txoj hauv kev siv hluav taws xob tsis tseem ceeb rau txoj kev loj hlob sai ntawm kev lag luam hluav taws xob niaj hnub no.
Cov khoom siv tseem ceeb: Hloov cov khoom siv hluav taws xob tau siv dav hauv kev lag luam automation tswj, cov cuab yeej siv tub rog, cov cuab yeej tshawb fawb, LED teeb pom kev zoo, cov cuab yeej tswj kev lag luam, cov khoom siv sib txuas lus, cov khoom siv hluav taws xob, cov cuab yeej siv, cov cuab yeej kho mob, semiconductor tub yees thiab cua sov, cua purifiers, hluav taws xob. tub yees, kua siv lead ua zaub, LED teeb, kev saib xyuas kev ruaj ntseg, cov khoom siv digital thiab cov cuab yeej siv thiab lwm yam haujlwm.
Basic muaj pes tsawg leeg ntawm switching fais fab mov
1. Main Circuit Court
Impulse tam sim no txwv: txwv lub impulse tam sim no nyob rau sab input thaum lub hwj chim qhib.
Input filter: Nws txoj haujlwm yog lim cov clutter uas muaj nyob rau hauv daim phiaj fais fab thiab tiv thaiv cov clutter tsim los ntawm lub tshuab tsis pub rov qab mus rau hauv daim phiaj fais fab.
Rectification thiab filtering: ncaj qha kho lub zog AC ntawm daim phiaj mus rau hauv lub zog DC ncaj qha.
Inverter: Tig txoj kev taw qhia rau hauv high-frequency alternating tam sim no, uas yog ib feem ntawm high-frequency switching fais fab mov.
Output rectification thiab filtering: Raws li cov kev xav tau ntawm lub load, muab ib tug ruaj khov thiab txhim khu kev qha DC fais fab mov.
2. Tswj Circuit Court
Ntawm qhov tod tes, cov qauv raug coj los ntawm qhov tso zis davhlau ya nyob twg thiab muab piv nrog cov nqi teev, thiab tom qab ntawd lub inverter yog tswj los hloov cov mem tes dav lossis mem tes zaus kom ruaj khov cov zis.Ntawm qhov tod tes, raws li cov ntaub ntawv muab los ntawm kev ntsuas Circuit Court, kev tiv thaiv Circuit Court muab Kev tswj xyuas Circuit Court ua rau ib tus neeg tiv thaiv kev ntsuas rau cov khoom siv hluav taws xob.
3. Kev kuaj xyuas Circuit Court
Muab cov ntaub ntawv ntawm ntau yam tsis muaj thiab ntau yam twj paj nruag hauv kev ua haujlwm hauv kev tiv thaiv Circuit Court.
4. Pab txhawb zog
Paub txog qhov software (chaw taws teeb) pib ntawm lub hwj chim, thiab muab lub zog rau kev tiv thaiv Circuit Court thiab tswj Circuit Court (chips xws li PWM)
