Qhov tseem ceeb ntawm AC / DC hloov fais fab adapter chips
AC / DC hloov lub hwj chim adapter adapter adapter nti (lossis module) tuaj yeem ua rau hauv lub zog hloov pauv los ntawm kev sib txuas qee cov hluav taws xob cuam tshuam thiab hloov pauv hloov.
Lub ntsiab ua haujlwm tseem ceeb ntawm ib nrab choj hloov fais fab hloov yog tias cov choj hloov pauv ntawm sab saud thiab qis dua (vmos thaum muaj lwm yam) hloov lwm yam. Ua ntej, tam sim no ntws nyob rau hauv lub choj sab sauv hloov lub raj, thiab cov khoom muaj nuj nqi ntawm inductor chev yog siv los sau hluav taws xob lub zog hauv lub kauj. Thaum kawg, tus choj hloov sab sab sab yog kaw thiab qis dua tus choj hloov lub raj tau qhib, thiab lub peev xwm indactror thiab capacitor txuas ntxiv mus muab lub zog rau sab nraud. Tom qab ntawd kaw cov raj hauv qab tus choj thiab qhib cov choj sab saud kom tso cai rau nkag mus, thiab rov ua tus txheej txheem no. Vim tias nws yuav tsum tau hloov hloov ntawm ob txoj hlua hloov, nws yog hu ua lub hloov fais fab adapter.
Raws li hloov lub zog IC hauv AC-DC lub zog hluav taws xob hloov kho. Lub ntsiab zoo ntawm ACC / DC hloov lub zog hloov pauv tau yog:
A: Me me thiab lub teeb hnyav (tsuas yog 20% mus rau 30% ntawm qhov loj thiab qhov hnyav ntawm cov ntaub qhwv hluav taws xob linear)
B: High efficiency (feem ntau yog 60% rau 70%, thaum cov kab hluav taws xob hloov kho tsuas muaj 30% rau 40%)
Muaj zog tiv thaiv kev cuam tshuam muaj peev xwm, dav kev tawm tsam ntau heev, thiab modularity.
Cov feem ntau siv tsawg-voltage ac hloov zog adapter powerity ncaj qha rau hauv ib qho hluav taws xob ntawm ib ncig ntawm 300v tom qab dhau los ntawm EMI Lim. Lub Circuit Court tswj tau lub raj hloov pauv thiab txiav tawm ntawm kev kub siab, thiab tom qab ntawd hloov pauv voltages, uas yog li ntawd rectified rau qhov xav tau AC voltage.
