Txhawm rau kom ua tiav qhov kev ua tau zoo ntawm lub tshuab hluav taws xob benchtop, nws yog ib qho tseem ceeb kom nkag siab txog nws cov hauv paus ntsiab lus. Lub rooj zaum hluav taws xob hloov pauv AC lub zog hluav taws xob los ntawm lub qhov hluav taws xob phab ntsa mus rau DC lub zog uas yog siv los ua lub zog rau ntau yam khoom hauv lub computer. Nws feem ntau ua haujlwm ntawm ib-theem AC input thiab muab ntau yam DC tso zis voltages, xws li +12V, -12V, +5V, thiab +3.3V.
Txhawm rau hloov AC lub zog nkag mus rau hauv DC lub zog, lub tshuab hluav taws xob siv hluav taws xob siv lub tshuab hluav taws xob los hloov cov hluav taws xob siab thiab tsis tshua muaj hluav taws xob tam sim no AC nkag mus rau hauv qhov hluav taws xob qis thiab siab dua tam sim no AC teeb liab. Lub teeb liab AC no yog tom qab kho siv diodes, uas hloov AC teeb liab mus rau hauv lub zog DC.
Txhawm rau ua kom lub zog tawm ntawm DC voltage, lub tshuab hluav taws xob siv hluav taws xob siv cov khoom siv hluav taws xob uas khaws cov nqi ntau dhau thiab tso tawm thaum lub sijhawm tsis tshua muaj hluav taws xob, ua rau muaj qhov ruaj khov DC tso zis ntau dua. Tom qab ntawd, DC voltage yog tswj los ntawm kev siv hluav taws xob hluav taws xob hluav taws xob los xyuas kom meej tias nws tseem nyob rau hauv nruj tolerances, tiv thaiv kev puas tsuaj rau cov khoom. Ntau yam kev tiv thaiv, xws li kev tiv thaiv overvoltage, kev tiv thaiv overcurrent, thiab kev tiv thaiv luv luv, kuj tau tsim rau hauv cov khoom siv hluav taws xob los tiv thaiv kev puas tsuaj rau cov khoom thaum muaj teeb meem.
Kev nkag siab txog cov hauv paus ntsiab lus ntawm lub desktop fais fab mov tuaj yeem pab xaiv cov khoom siv hluav taws xob tsim nyog rau lub khoos phis tawj thiab ua kom pom kev ua haujlwm zoo.
Hauv tsab xov xwm no, peb yuav hais txog cov hauv paus ntsiab lus ntawm cov khoom siv hluav taws xob lub rooj zaum yog dab tsi, yuav siv nws li cas kom raug, thiab yuav tsum nrhiav dab tsi thaum xaiv tus qauv.
Benchtop Power Supply yog dab tsi?
Thaum koj tab tom ua haujlwm ntawm qhov project uas yuav tsum muaj qhov tseeb ntawm DC lub zog, lub rooj zaum fais fab tuaj yeem tuaj yeem ua ke. Qhov tseem ceeb yog lub zog me me uas tsim los zaum ntawm koj lub rooj zaum ua haujlwm.
Cov khoom siv no tseem hu ua cov khoom siv hluav taws xob hauv chaw kuaj mob, cov khoom siv hluav taws xob DC, thiab cov khoom siv hluav taws xob programmable. Lawv zoo meej rau cov khoom siv hluav taws xob rau cov neeg uas xav tau kev nkag mus rau lub zog siv tau yooj yim thiab yooj yim siv.
Thaum muaj ntau hom khoom siv hluav taws xob hauv lub rooj zaum muaj - suav nrog cov khoom siv sib txuas lus, ntau hom tso zis, thiab muaj ntau yam nta - lawv txhua tus tsim los ua kom koj cov haujlwm yooj yim dua thiab raug dua.
Nws ua haujlwm li cas?
Lub rooj zaum fais fab mov yog ib qho khoom siv ntau yam uas muab kev tswj hwm lub zog rau cov khoom siv hluav taws xob. Nws ua haujlwm los ntawm kev kos duab AC fais fab los ntawm lub hauv paus thiab lim nws kom muab cov zis DC tas li. Cov txheej txheem suav nrog ntau yam, suav nrog transformer, rectifier, capacitor, thiab voltage regulator.
Piv txwv li, nyob rau hauv ib tug linear fais fab mov, lub transformer nqis los ntawm voltage mus rau ib tug tswj theem, lub rectifier converts AC tam sim no mus rau DC, lub capacitor lim tawm cov suab nrov ntxiv, thiab lub voltage regulator kom ruaj khov DC tso zis. Nrog lub peev xwm los kho qhov hluav taws xob thiab qib tam sim no thiab tiv thaiv cov khoom siv los ntawm kev siv hluav taws xob ntau dhau, lub tshuab hluav taws xob lub rooj zaum yog ib qho tseem ceeb rau kev tshuaj xyuas tsis siv neeg, kev pabcuam hauv tsev kawm ntawv, thiab lwm yam.
Vim li cas thiaj tseem ceeb?
Lub rooj zaum lub rooj zaum fais fab yuav tsis yog cov khoom siv zoo nkauj tshaj plaws hauv lub tshuab hluav taws xob lub chaw kuaj mob, tab sis nws qhov tseem ceeb tsis tuaj yeem hais ntau dhau. Yog tsis muaj ib qho, kev sim thiab prototyping yuav ua tsis tau nyob rau hauv thawj qhov chaw.
Cov khoom siv hluav taws xob hauv Benchtop muab qhov chaw ruaj khov thiab ruaj khov ntawm qhov hluav taws xob rau kev sim thiab siv hluav taws xob hauv hluav taws xob. Lawv tso cai rau cov engineers sib txawv ntawm qhov voltage thiab tam sim no rau cov khoom siv los ntsuas lawv cov kev txwv, saib seb lawv ua li cas hauv cov ntawv thov sib txawv, thiab xyuas kom lawv ua haujlwm kom raug hauv cov khoom kawg.
Kev nqis peev hauv lub tshuab hluav taws xob zoo yuav tsis zoo li qhov kev yuav khoom flashiest. Txawm li cas los xij, nws tuaj yeem ua rau muaj kev cuam tshuam loj rau kev ua tiav thiab kev ua haujlwm ntawm kev tsim hluav taws xob thiab kev tsim kho.
