Hom thiab cov ntawv thov ntawm hloov hluav taws xob siv hluav taws xob
Muaj ob hom niaj hnub hloov hluav taws xob cov khoom siv fais fab tuag: Ib qho yog DC hloov fais fab tuag; Lwm hom yog AC hloov fais fab mov. Lub ntsiab tseem ceeb ntawm no yog nyob rau DC switching fais fab khoom, nws muaj txoj haujlwm muaj hwj chim loj (coks hluav taws xob rau hauv cov khoom siv hluav taws xob zoo tshaj plaws (cov hluav taws xob zoo) uas tau raws cov cuab yeej siv.
Cov tub ntxhais ntawm DC hloov fais fab khoom yog DC / DC converter. Yog li ntawd, kev faib tawm DC Switching Powering fais fab khoom yog nyob ntawm kev faib tawm ntawm DC / DC Conterers. Qhov ntawd yog hais, kev faib tawm DC Switching Powering Powering Powerers, thiab kev faib tawm ntawm DC hloov fais fab khoom siv.
Hloov chaw hluav taws xob yog ib hom fais fab mov uas siv cov hluav taws xob siv hluav taws xob niaj hnub no los tswj cov transistive tig thiab tawm, tswj cov kev tawm tsam ruaj khov. Hloov chaw hluav taws xob feem ntau muaj ntawm cov mem tes dav dav (PWM) tswj IC thiab hloov cov cuab yeej siv (Mosfet, BJT, thiab lwm yam). Kev loj heev yog qhov kev taw qhia ntawm nws txoj kev txhim kho, uas ua rau hloov fais fab dua thiab siv dav dua, tshwj xeeb tshaj yog nyob hauv cov miniaturization thiab qhov tseem ceeb ntawm cov khoom lag luam siab.
Ib qho ntxiv, kev txhim kho thiab kev siv ntawm hloov hom hwj huam yog qhov tseem ceeb hauv kev txuag hluav taws xob, kev tiv thaiv kev txuag ib puag ncig. Tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov high-tech, kev txhim kho ntawm hloov cov khoom siv fais fab ntawm ob lub teeb, me me, lub suab qis, muaj kev ntseeg siab.
Piv rau cov khoom siv hluav taws xob tawm, tus nqi ntawm ob qho hloov hluav taws xob nce nrog kev nce cov zis zog, tab sis lawv cov nqi kev loj hlob muaj sib txawv. Tus nqi ntawm cov khoom siv fais fab linear yog qhov ua tau zoo dua li ntawm kev hloov fais fab fais fab ntawm qee yam tso zis hwj chim taw tes. Nrog rau kev txhim kho thiab kev tsim kho lub zog hluav taws xob tshuab, hloov fais fab kev ua kom muaj zog, muab ntau qhov chaw tsim kho kom hloov cov khoom siv hluav taws xob. Kev loj zaus hloov chaw fais fab yog nws txoj kev txhim kho.
