Jjw 3-2000 va uniross tswj hwm AC DC adapter

Uniross tswj hwm AC DC adapter tseem hu ua DC Voltage Regulator. Nws cov khoom siv hluav taws xob voltage feem ntau yog AC Voltage, thaum cov hluav taws xob ntsaws voltage ntawm cov regulator tuaj yeem nyob ruaj khov. Lub uniross tswj hwm AC DC adapter ntawm cov kev tswj hwm muaj feem cuam txheeb xyuas ruaj khov, cov roj ci me me thiab kev teb ceev. Tus qub sawv cev rau cov nyhuv ntawm kev hloov pauv hauv cov lus qhia voltage ntawm cov zis hluav taws xob. Cov ripple chefficied sawv cev rau AC tivthaiv ntawm cov zis hluav taws xob nyob hauv txoj kev ua haujlwm ,. Lub tom kawg qhia lub sijhawm rau lub sijhawm uas yuav tsum tau rov qab los rau ib txwm muaj thaum cov tswv yim voltage lossis thauj cov hloov pauv hloov pauv. DC voltage dob stabilized zog muab faib ua txuas ntxiv mus txuas hom txuas ntxiv mus txuas ntxiv thiab hloov ob hom. Cov kev hloov qub hloov ib leeg-theem lossis peb-theem poltage rau cov nqi hluav taws xob tsim nyog los ntawm lub zog hluav taws xob (thiab tom qab ntawd tau txais lub zog hluav taws xob (lossis tom qab ntawd tau txais cov hluav taws xob ruaj khov (lossis tom qab ntawd tau txais cov hluav taws xob ruaj khov (lossis tom qab ntawd) los ntawm cov kev tswj hluav taws xob ruaj khov. Qhov hluav taws xob hluav taws xob no yog qhov yooj yim, me me ripple, kev cuam tshuam me me, ntau cov neeg siv khoom, feem ntau tsawg dua 40% rau 60%). Cov tom kawg kho cov zis hluav taws xob los ntawm kev hloov lub sijhawm tawm ntawm lub sijhawm hloov kho (lossis hloov) kom ua tiav voltage cov cai. Qhov kev siv fais fab tuag yog me me, kev ua tau zoo tuaj yeem ncav cuag txog 85%, tab sis qhov tsis zoo yog loj cuam tshuam thiab cuam tshuam loj. Yog li ntawd, txoj kev loj hlob tau nrawm txij li xyoo 1980s. Los ntawm txoj kev ua haujlwm tuaj yeem faib ua:

① Cov txheej txheem tswj hwm hom. Kho cov zis hluav taws xob los ntawm kev hloov lub sijhawm uas tab ntawm cov thyristor.

② Cho yuam hom. Cov tswv yim tsis khov dc voltage, kom hloov pauv ntawm-tawg piv rau tau txais ib txoj kev hloov kho DC, thiab tom qab ntawd lim kom tau txais ruaj ruaj dc voltage.

③ Hloov hom. Tsis khov DC voltage yog thawj hloov dua siab tshiab AC los ntawm inverter ua haujlwm ntau zaus, kom ua tiav lub hom phiaj ntawm cov khoom siv tsis ruaj khov, kom ua tiav lub hom phiaj ntawm cov khoom siv hluav taws xob ruaj khov DC voltage.
