Hloov hom fais fab mov txoj cai thiab cov yam ntxwv
Txoj Cai Ua Haujlwm
DC switching fais fab mov muaj xws li input ib feem, lub hwj chim hloov dua siab tshiab ib feem, tso zis ib feem thiab tswj ib feem. Lub zog hloov dua siab tshiab ib feem yog lub hauv paus ntawm cov khoom siv hluav taws xob hloov hluav taws xob, uas ua rau cov khoom siv hluav taws xob ntau zaus ntawm DC tsis ruaj khov thiab ua tiav cov kev hloov pauv uas xav tau rau cov zis. Nws yog tsuas yog tsim los ntawm kev hloov transistors thiab high-frequency transformers. Daim duab 1 kos lub schematic thiab sib npaug daim duab ntawm DC switching fais fab mov, uas yog tsim los ntawm ib tug tag nrho-yoj rectifier, ib tug switching tube V, ib tug excitation teeb liab, ib tug tam sim no-renewal diode Vp, lub zog cia inductor thiab ib tug filtering capacitor. C. Qhov tseeb, qhov tseem ceeb ntawm DC switching fais fab mov yog DC transformer.

Txhawm rau hloov mus rau cov kev xav tau ntawm cov neeg siv, cov tuam txhab loj hauv tsev thiab txawv teb chaws hloov hluav taws xob hloov hluav taws xob tau cog lus rau kev tsim kho ib txhij ntawm cov khoom siv ntse tshiab, tshwj xeeb tshaj yog los ntawm kev txhim kho qhov poob ntawm cov khoom siv hluav taws xob thib ob, thiab nce kev tshawb fawb thiab thev naus laus zis hauv lub zog. ferrite (Mn-Zn) cov ntaub ntawv los txhim kho lub siab zaus thiab cov flux loj dua kom tau txais qib siab ntawm cov khoom sib nqus, thaum daim ntawv thov ntawm SMT thev naus laus zis tau ua rau muaj kev vam meej hauv kev hloov hluav taws xob. Cheebtsam yog teem rau ntawm ob sab ntawm lub rooj tsavxwm Circuit Court los xyuas kom meej tias lub switching fais fab mov yog lub teeb, me me thiab nyias. Yog li ntawd, txoj kev loj hlob ntawm DC switching fais fab mov yog siab zaus, muaj kev ntseeg siab, tsawg noj, tsis tshua muaj suab nrov, tiv thaiv kev cuam tshuam thiab modularity.
Qhov tsis zoo ntawm DC hloov hluav taws xob yog tias muaj kev cuam tshuam loj dua, kev muaj peev xwm hloov mus rau qhov chaw hnyav thiab tsis muaj zog tam sim ntawd. Vim yog lub hauv paus microelectronics technology, capacitive resistance ntaus ntawv ntau lawm technology thiab magnetic khoom technology thiab ib co technologically advanced lub teb chaws tseem muaj ib tug tej yam txawv, yog li cov zus tau tej cov DC switching fais fab mov kev teeb meem, txij nkawm teeb meem thiab tus nqi siab.
