Hom thiab kev siv ntawm cov khoom siv hluav taws xob hloov pauv
Muaj ob hom kev hloov hluav taws xob niaj hnub: ib qho yog DC hloov hluav taws xob; Lwm qhov yog AC switching fais fab mov. Cov lus qhia tseem ceeb ntawm no tsuas yog DC hloov hluav taws xob, nws txoj haujlwm yog los hloov cov khoom siv hluav taws xob qub nrog cov hluav taws xob tsis zoo (lub zog ntxhib), xws li hluav taws xob hluav taws xob lossis roj teeb hluav taws xob, rau hauv DC voltage (lub zog zoo) nrog cov khoom zoo dua. kom ua tau raws li cov kev cai ntawm cov khoom siv.
Lub hauv paus ntawm DC hloov fais fab mov yog DC / DC converter. Yog li, kev faib tawm ntawm DC hloov hluav taws xob yog nyob ntawm kev faib tawm ntawm DC / DC converter. Qhov ntawd yog hais tias, kev faib tawm ntawm DC hloov hluav taws xob yog qhov tseem ceeb tib yam li kev faib tawm ntawm DC / DC converter, thiab kev faib tawm ntawm DC / DC converter yog qhov kev faib tawm ntawm DC hloov hluav taws xob.
Kev hloov pauv hluav taws xob yog siv cov cuab yeej hluav taws xob niaj hnub siv hluav taws xob, tswj kev hloov pauv hloov pauv hloov pauv ntawm lub sijhawm thiab lub sijhawm tawm, kom tswj tau qhov tso tawm hluav taws xob ruaj khov ntawm lub zog hluav taws xob, hloov hluav taws xob feem ntau yog los ntawm pulse width modulation (PWM) tswj IC thiab cov khoom siv hloov pauv (MOSFET, BJT, thiab lwm yam) tsim cov khoom siv hluav taws xob hloov hluav taws xob ntau zaus yog cov kev taw qhia ntawm nws txoj kev loj hlob, high-frequency switching power supply miniaturization thiab switching power supply kom nkag mus rau ntau qhov chaw ntawm Daim Ntawv Thov, tshwj xeeb tshaj yog nyob rau hauv lub teb ntawm high-tech daim ntaub ntawv, los txhawb lub miniaturization ntawm high-tech khoom, lub teeb yuag.
