Qhov sib txawv ntawm AC rau DC fais fab mov thiab DC rau DC fais fab mov.
Hauv ntiaj teb ntawm cov tshuab fais fab, Alternating Current (AC) thiab Direct Current (DC) yog ob hom hluav taws xob uas siv ntau. AC yog ib qho hluav taws xob uas hloov pauv tas li, thaum DC yog ib qho hluav taws xob uas ntws tas li hauv ib qho kev taw qhia. Thaum xaiv lub zog fais fab, peb tuaj yeem xaiv ntawm AC rau DC lossis Dc Mus Rau Dc raws li peb cov kev xav tau.
Kev muab hluav taws xob AC/DC yog ib lub cuab yeej uas hloov AC mus rau hauv DC. Qhov kev hloov pauv no feem ntau ua tiav los ntawm kev kho. Lub rectifier hloov AC lub zog mus rau hauv DC lub zog nrog kev taw qhia tas mus li. Diodes feem ntau siv hauv rectifiers vim tias lawv tsuas yog tso cai rau tam sim no ntws mus rau hauv ib qho kev taw qhia. Lub rectifier tuaj yeem yog ib nrab-yoj rectifier lossis ib qho puv-yoj rectifier. Ib nrab-yoj rectifiers tso cai tsuas yog ib nrab ntawm AC voj voog kom dhau, thaum puv-yoj rectifiers tso cai rau tag nrho AC voj voog kom dhau. Capacitors feem ntau siv ua ke nrog rectifiers kom du cov zis DC tam sim no.
DC/DC fais fab mov yog ib lub cuab yeej uas hloov DC mus rau ntau qib voltage lossis tam sim no. Qhov kev hloov pauv no feem ntau ua tiav los ntawm lub DC-DC converter.
Ib lub DC-DC converter tuaj yeem tsa lossis txo qhov input voltage kom muab qhov output voltage siab dua lossis qis dua. Lawv kuj tuaj yeem tsa lossis txo qhov input tam sim no kom muab qhov output tam sim no siab dua lossis qis dua. Cov DC-DC converters feem ntau siv cov thev naus laus zis switching mode power supply. Switching mode power supplies siv cov khoom siv switching, xws li transistors lossis MOSFETs, los tswj cov dej ntws ntawm tam sim no. Kev tswj lub sijhawm hloov thiab zaus ntawm cov khoom siv no, qhov voltage lossis tam sim no hloov pauv tuaj yeem ua tiav.
Cov khoom siv fais fab AC rau DC thiab cov khoom siv fais fab DC rau DC muaj kev siv sib txawv hauv ntau daim ntawv thov. Cov khoom siv fais fab AC/DC feem ntau siv rau hauv cov khoom siv hauv tsev, cov khoom siv hluav taws xob, thiab cov khoos phis tawj uas xav tau fais fab DC.
Ntawm qhov tod tes, cov khoom siv fais fab DC-rau-DC feem ntau siv rau hauv cov tsheb fais fab, cov vaj huam sib luag hnub ci, thiab cov khoom siv sib txuas lus wireless uas xav tau cov hluav taws xob sib txawv lossis cov theem tam sim no. Cov khoom siv fais fab AC rau DC thiab cov khoom siv fais fab DC tam sim no ua lub luag haujlwm tseem ceeb hauv cov tshuab fais fab, uas tso cai rau peb muab cov khoom siv fais fab ruaj khov thiab txhim khu kev qha raws li cov kev xav tau fais fab sib txawv.
Hauv ntej, cov khoom siv fais fab AC rau DC thiab cov khoom siv fais fab DC ncaj qha yog cov khoom siv sib xws hauv cov tshuab fais fab, muab rau peb cov kev xav tau fais fab ruaj khov thiab txhim khu kev qha.
