Kev tsim tshwj xeeb kev daws teeb meem thiab cov yam ntxwv rau kev sib txuas ntawm cov khoom siv hluav taws xob sib txuas
Piv nrog rau cov khoom siv hluav taws xob hloov pauv ib txwm muaj, tshwj xeeb kev sib txuas hluav taws xob hloov hluav taws xob muaj cov yam ntxwv ntawm cov khoom siv hluav taws xob tshiab, kev ua haujlwm tshwj xeeb, kev ua haujlwm siab heev thiab kev siv dav dua. Feem ntau tshwj xeeb kev sib txuas hluav taws xob hloov hluav taws xob feem ntau siv monolithic hloov hluav taws xob hloov hluav taws xob sib xyaw ua ke, ua ke nrog cov khoom siv hluav taws xob sib txuas (xws li kev tswj lub voj voog) tsim kom muaj cov yam ntxwv sib txawv thiab daim ntawv thov thaj chaw, kom tau raws li qhov xav tau ntawm cov neeg siv sib txawv.
Tshwj xeeb integrated switching fais fab mov feem ntau suav nrog tsib hom hauv qab no:
(1) Composite switching fais fab mov;
(2) Tsis tu ncua voltage / tsis tu ncua tam sim no (CV / CC) hom hloov hluav taws xob;
(3) txiav tawm tam sim no tso zis hom hloov fais fab mov;
(4) tsis tu ncua fais fab tso zis hom hloov fais fab mov;
(5) lwm yam tshwj xeeb hloov fais fab mov, xws li high-speed modem (HighSpeedModem) fais fab mov, DVD fais fab mov.
Tshwj xeeb integrated switching fais fab mov tsim kev daws teeb meem thiab nta
Tshwj xeeb monolithic switching fais fab mov muaj ob lub tswv yim tsim: thawj yog kev siv lub hom phiaj monolithic switching fais fab mov integrated circuits (xws li, TOPSwitch-II, TOPSwitch-FX, TOPSwitch-GX, thiab lwm yam), thiab tom qab ntawd nrog cov voltage. tswj voj, tam sim no tswj voj thiab lwm yam Peripheral circuits tsim, uas yog yus muaj los ntawm cov zis ntau zog, tab sis lub peripheral Circuit Court yog complex; Qhov thib ob yog kev siv cov LinkSwitch tsis ntev los no qhia txog kev ua haujlwm siab tsis tu ncua voltage / tas li-tam sim no peb lub davhlau ya nyob twg monolithic switching fais fab mov nti, lossis siv LinkSwitch-TN series, DpA-Switch series ntawm monolithic Switching fais fab mov nplooj siab IC, uas tuaj yeem ua kom yooj yim rau hauv Circuit Court, txo cov nqi, tsim nyog rau cov khoom siv hluav taws xob nruab nrab thiab me me tshwj xeeb hloov hluav taws xob.
Tshwj xeeb integrated switching power supply kev ua tau zoo yam ntxwv
(1) Kev siv cov khoom siv hluav taws xob tsis tu ncua / qhov tam sim no monolithic hloov hluav taws xob LNK500, AC input voltage ntau ntawm 85 ~ 265V, thaum AC input voltage ntawm 265V, to tam sim no<5μA, rated output voltage of 5.5V, the maximum output current of 0.45A, the output power of 2.5W.
2) Kev siv hluav taws xob tsawg, kev ua haujlwm siab, tsis muaj lub zog siv hluav taws xob<0.3W, typical value of power supply efficiency η ≈ 68%.
3) Ntawm qhov taw tes lub zog siab, qhov tso zis hluav taws xob tau tso cai kom muaj ± 10% yuam kev thaum thawj.
5) Nrog kev tiv thaiv overheat, tso tawm luv Circuit Court tiv thaiv thiab qhib lub voj tiv thaiv.
6) Ua raws li tus qauv thoob ntiaj teb CISpR22B / EN55022B rau electromagnetic compatibility.
