Dc fais fab PWM siv thev naus laus zis, qhov zoo thiab kev txwv

Pulse-width modulation yog txheej txheem los tswj lub sijhawm piv ntawm cov khoom siv hluav taws xob hloov pauv los ntawm kev kho cov mem tes dav lossis lub sijhawm los tswj cov zis hluav taws xob. Vim nws txoj kev tiv thaiv zoo ntawm kev hu xov tooj, cov lus teb zoo dynamic, qhov zoo ntawm qhov zaus thiab kev ua haujlwm zoo, nws tau siv dav hauv hluav taws xob inverters, thiab nws cov thev naus laus zis tau dhau los ua ntau dua. PWM tswj tshuab tau dav siv hauv inverter Circuit Court, uas muaj kev cuam tshuam loj tshaj plaws ntawm inverter circuit. Tam sim no, PWM inverter Circuit Court yog siv nyob rau hauv ntau lub inverter circuits. Hauv luv luv, koj tuaj yeem yooj yim stabilize cov zis voltage.

PWM technology ua haujlwm li cas?

PWM thev naus laus zis yog cov txheej txheem uas tswj cov zis hluav taws xob los ntawm kev kho lub sijhawm hloov pauv ntawm kev hloov pauv. PWM thev naus laus zis feem ntau ua tiav kev hloov hluav taws xob los ntawm kev tswj Circuit Court. Kev tswj Circuit Court tswj lub sij hawm ntawm qhov hloov raws li qhov sib txawv ntawm qhov tso zis hluav taws xob thiab qhov muab hluav taws xob kom ua tiav lub hom phiaj tso tawm hluav taws xob ruaj khov.

Qhov zoo ntawm PWM technology

1. ruaj khov tso zis voltage

PWM thev naus laus zis tswj lub sijhawm ua haujlwm ntawm qhov hloov mus ua kom tiav kev tswj hwm ntawm cov zis hluav taws xob. PWM thev naus laus zis ua rau cov zis hluav taws xob tswj tau ruaj khov dua li cov txheej txheem kev hloov kho ib txwm muaj, txhim kho kev ruaj ntseg thiab kev ntseeg siab ntawm kev hloov pauv DC fais fab mov.

2. Txhim kho lub zog efficiency

PWM thev naus laus zis txo cov hluav taws xob poob los ntawm kev hloov cov khoom siv hluav taws xob rau hauv cov cim mem tes siab. Nyob rau tib lub sijhawm, PWM thev naus laus zis tuaj yeem tswj lub sijhawm hloov pauv ntawm qhov hloov pauv, txo qhov poob ntawm qhov hloov pauv hauv lub xeev wired, thiab yog li txhim kho lub zog ua haujlwm.

3. Paub ntau qhov tso zis voltages

Los ntawm kev tswj lub sijhawm hloov pauv, PWM thev naus laus zis tuaj yeem ua tiav ntau yam ntawm cov zis hluav taws xob. Piv txwv li, hauv cov khoom siv hluav taws xob hauv computer, PWM thev naus laus zis tuaj yeem ua tiav cov zis sib txawv, xws li 12V, 5V, thiab 3.3V, kom tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob sib txawv.

4. Siv kev tiv thaiv kev ruaj ntseg

Wide pulse modulation technology tswj lub sijhawm ua haujlwm ntawm kev hloov kom ua tiav kev tiv thaiv lub zog. Piv txwv li, hauv cov khoom siv hluav taws xob, PWM thev naus laus zis tuaj yeem tiv thaiv kev nyab xeeb ntawm cov khoom siv hluav taws xob los ntawm kev tswj lub sijhawm hloov pauv ntawm kev hloov thiab txiav tawm lub zog hluav taws xob thaum qhov hluav taws xob siab dhau lossis qis dhau.

The limitations of PWM technology

1. Lub suab nrov: PWM thev naus laus zis tsim cov teeb liab mem tes siab, uas ua rau muaj kev cuam tshuam ntawm hluav taws xob thiab suab nrov, cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob.

2. Tus nqi siab: PWM thev naus laus zis yuav tsum muaj kev tswj xyuas tshwj xeeb thiab cov keyboards, thiab nws kim heev.

3. Cov kev xav tau siab rau cov keyboards: PWM thev naus laus zis xav tau cov keyboards ceev. Kev kub ceev hloov cov raj muaj qhov xav tau siab rau kev hloov cov raj.

Hauv cov ntsiab lus, PWM thev naus laus zis yog cov cuab yeej siv dav tshaj plaws hauv kev hloov pauv DC cov khoom siv hluav taws xob. Nws muaj qhov zoo ntawm kev ruaj ntseg zoo, kev ua haujlwm siab, thiab kev ntseeg siab. Txawm li cas los xij, PWM thev naus laus zis kuj muaj nws cov kev txwv. Xws li lub suab nrov, tus nqi siab, thiab kev xav tau siab rau kev hloov cov raj. Yog li ntawd, txhawm rau ua kom tau raws li cov kev cai ntawm cov khoom siv hluav taws xob hauv kev siv tswv yim, nws yog ib qho tsim nyog yuav tsum xaiv cov cuab yeej tswj kom tsim nyog raws li qhov xwm txheej tshwj xeeb.
