Vim li cas ho tsis tuaj yeem siv lub tshuab hloov pauv hloov pauv raws li lub zog hloov pauv hloov tau?
Lub sine nthwv dej huv yog tsim los ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv ntawm AC-DC-AC hloov pauv ntawm cov hloov tam sim no hauv lub zog loj. Ob qhov tso zis voltage thiab zaus tuaj yeem hloov pauv hauv ib qho tshwj xeeb. Nws tuaj yeem hloov pauv tag nrho cov haujlwm ntawm qhov hloov pauv zaus thiab nquag siv. Nws ua haujlwm raws li cov khoom siv hluav taws xob dav dav thiab tuaj yeem tiv thaiv lub cuab yeej zoo dua.
Lub zog sib txawv ntawm cov khoom siv hluav taws xob tsis tshua muaj nyob ze rau qhov zoo tshaj plaws AC fais fab mov nyob rau hauv uas nws tuaj yeem tso tawm qhov hluav taws xob hluav taws xob thiab zaus ntawm txhua lub teb chaws thiab siv rau cov khoom sib txawv ntawm impedance yam ntxwv, xws li resistive, capacitive, inductive, thiab lwm yam tsis-linear. load cuam tshuam. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ntau hom kev thauj khoom hu rau ntau lub zog muaj peev xwm los ntawm qhov sib txawv ntawm lub zog hluav taws xob.
Lwm lub npe rau lub zaus hloov pauv yog qhov hloov pauv hloov ceev ceev. Lub cev muaj zog ceev yog tswj thiab hloov los ntawm lub zaus converter. Nws ua haujlwm feem ntau nrog lub cev muaj zog. Nws cov zis voltage muaj ib tug mem tes square yoj duab nrog ntau yam harmonics. Nws yuav ua mob rau cov khoom siv txawv teb chaws yog tias nws siv los kuaj xyuas nws. loj tiag tiag. Nws tsis ua tau raws li cov qauv ntawm AC fais fab mov vim tias nws qhov voltage thiab zaus hloov pauv raws tib lub sijhawm thiab tsis tuaj yeem hloov kho ib tus zuj zus. Los ntawm kev hloov cov zaus ntawm lub cev muaj zog lub zog ua haujlwm, lub zaus hloov pauv yog lub zog tswj cov cuab yeej siv microelectronics thiab zaus hloov tshuab los tswj AC motors.
Cov neeg siv tuaj yeem simulate thoob ntiaj teb voltages thiab zaus thiab tau txais cov ntaub ntawv sim ua kom raug los ntawm kev xaiv lub zog tsim nyog. Tom qab txheeb xyuas cov khoom siv hluav taws xob sib txawv thiab cov khoom siv zaus hloov pauv, kuv xav tias txhua tus neeg muaj kev nkag siab zoo ntawm lawv cov khoom siv hluav taws xob tso tawm nrog rau ntau yam teeb meem uas tshwm sim los ntawm kev siv cov zaus hloov pauv hauv chav kuaj. Qhov kev paub no ua lub hauv paus rau lub chaw soj nstuam xaiv cov khoom siv hluav taws xob hloov hluav taws xob tsim nyog.
Qhov no yog vim lub fact tias cov kws txawj nyob rau hauv mechanical engineering, uas muaj ib tug tsawg dua kev nkag siab nyob rau hauv hluav taws xob engineering, tsuas tuaj yeem ua kom cov khoom ua tau zoo ntawm cov khoom siv thiab hom kev sim thiab pab kom tsis txhob muaj kev cuam tshuam thoob ntiaj teb cov khoom xa tuaj los ntawm kev ua tib zoo xaiv cov khoom siv hluav taws xob hauv tsev. Cov khoom siv hluav taws xob sib txawv sib txawv yog qhov kev xaiv zoo tshaj plaws thaum nws los txog rau cov khoom siv hluav taws xob tshwj xeeb!
