Lub tshuab hluav taws xob txuas hluav taws xob tag nrho yog hluav taws xob hluav taws xob uas hloov AC tam sim no mus rau DC tam sim no. Cov hluav taws xob uas tawm los ntawm lub qhov (socket) yog AC tam sim no, thaum cov khoom siv hluav taws xob niaj hnub no tau siv los ntawm DC tam sim no. Qhov no txhais tau tias tag nrho yoj choj choj rectifier yog ib qho uas nquag thiab muaj txiaj ntsig hauv Circuit Court. Hauv qhov kev qhia no, peb yuav tsim lub yoj choj choj rectifier siv cov khoom yooj yim, pheej yig. Qhov tshwj xeeb no yuav hloov 120V AC tam sim no rau 6V DC tam sim no. Hauv qhov no, 1k ohm resistor yog lub load hauv Circuit Court, tab sis hauv daim ntawv thov siv tau, lub load yuav yog qee yam khoom siv hluav taws xob. Cov lus piav qhia ntxaws ntxaws txog qhov kev ua haujlwm hauv Circuit no tuaj yeem pom ntawm no: Full Wave Bridge Rectifier. Ib qho kev sim ntawm qhov Circuit no tuaj yeem pom ntawm no: Tag Nrho Wave Choj Rectifier Simulation

Kauj Ruam 1: Nkag Siab Koj Cov Cheeb Tsam

Ua ntej pib kev sib dhos, nws yog ib qho tseem ceeb uas peb paub tias cov khoom ua haujlwm zoo li cas thiab txoj hauv kev los teeb tsa lawv li cas.

Ua ntej tshaj, nco koj tus kheej tias lub khob cij ua haujlwm li cas. Ob kab ntawm ob sab ntawm lub khob cij (ntawm kab liab thiab xiav) yog cov kab hluav taws xob tau txuas nrog hluav taws xob raws qhov ntev ntawm lub khob cij. Lub caij no, cov kab sab hauv tau txuas nrog hluav taws xob raws qhov dav ntawm lub khob cij, tab sis tsis hla hla qhov faib nruab nrab. Hauv qhov kev tsim qauv no, peb yuav siv qhov kev faib ua haujlwm nruab nrab kom peb tau txais txiaj ntsig los nthuav tawm cov khoom sib txuas thiab ua kom lub tshuab ntxhua khaub ncaws huv.

Ntxiv mus, yuav tsum paub tias diodes tsuas yog ua rau hauv ib qho kev taw qhia, thiab nws yog qhov tsim nyog tias cov diodes tau taw qhia rau hauv txoj kev yog rau kev ua haujlwm. Cov diodes siv hauv txoj haujlwm no coj los ntawm sab dub mus rau sab nyiaj (hais txog lub cim cim rau lub diode, sab nyiaj yog sab uas "xub" taw qhia rau.)

Thaum kawg, nco ntsoov tias lub capacitor yog cov lus qhia tshwj xeeb ib yam nkaus, thiab cov hluav taws xob yuav tsum ntws los ntawm cov ceg luv mus rau ceg ntev ntawm lub capacitor.

Kauj Ruam 2: Sib dhos Circuit

Tam sim no khaws cov lus qhia ntawm cov khoom siv hauv siab, sib sau ua ke hauv Circuit Court raws li cov txheej txheem thiab daim duab muab. Thaum cov pins tshwj xeeb uas cov khoom siv tso rau hauv yuav tsum tsis zoo ib yam li hauv daim duab, cov khoom siv yuav tsum txuas nrog hluav taws xob tib yam nkaus li piv txwv li cov khoom sib dhos hauv tib kab hauv peb kab lus yuav tsum yog tib kab ib yam li hauv koj li.

Kauj Ruam 3: Txuas rau Transformer

Siv cov xov hluav taws xob txuas, txuas cov hlua hluav taws xob mus rau qhov tsim tawm ntawm AC hloov pauv. Rau kev nyab xeeb, xyuas kom lub tshuab hluav taws xob tsis ntsaws! Rau qee qhov kev hloov pauv (xws li ib qho siv hauv daim duab) nws yuav tsim nyog siv lub ciaj ntswj lossis tus ntswj kom nruj cov txiv ntoo uas txuas cov xov hlau. Qhov no yuav ua rau koj lub Circuit nrog 6V AC tom qab nws hloov pauv los ntawm 120V AC uas tawm ntawm phab ntsa. Tom qab koj ntsaws rau hauv lub tshuab hloov pauv, xyuas kom tseeb tias koj hnov tsw qee yam hlawv lossis haus luam yeeb thiab tshem tawm tam sim tam sim ntawd.

Kauj Ruam 4: Kuaj Koj Li Circuit Court

Txij ntawm no mus, lub Circuit Court yuav tsum ua haujlwm tau zoo, tab sis peb tsis tuaj yeem qhia tau tshwj tsis yog peb ntsuas ntsuas. Txhawm rau ua qhov no, peb yuav siv oscilloscope. Qhib koj lub oscilloscope thiab txuas qhov kev sojntsuam hla tus tiv thaiv ntawm lub Circuit Court raws li qhia hauv daim duab. Kho qhov ntsuas ntawm qhov oscilloscope kom txog thaum koj pom cov kab ncaj ncaj nyob ib puag ncig 3.5 V nrog lub suab me me zoo li hauv daim duab saum toj no. Cov ripples no yog tshwm sim los ntawm lub capacitor them thiab tso hluav taws xob.

Kauj Ruam 5: Troubleshooting/Cov Lus Qhia

Ua ntej tshaj plaws, thaum sib dhos lub voj voog no, nws tau pom zoo tias txhua yam khoom siv tau nthuav tawm ncaj qha rau ntawm lub khob cij. Qhov no tsis tsuas yog ua kom yooj yim rau kev teeb tsa hauv koj lub rooj sib txoos tab sis kuj ua rau nws tsis tshua muaj qhov uas ob lub ntsej muag kov thiab luv Circuit Court. Tsis tas li, nco ntsoov nias koj cov xov hlau thiab cov khoom sib txuas tau nias tag nrho kom lawv tsim hluav taws xob txuas nrog lub khob cij.

Raws li tau hais tseg hauv qib 1, xyuas kom tseeb tias txhua yam ntawm koj cov khoom siv tau qhia kom raug, tshwj xeeb tshaj yog thaum diodes vim lawv tsuas ua haujlwm hauv ib qho kev qhia.

Yog tias qhov tso tawm ntawm oscilloscope tsis zoo, xyuas kom qhov ntsuas tau raug. Nws raug nquahu kom koj pib nrog qhov ua haujlwm tshwj xeeb thiab mus los ntawm qhov ntawd. Yog tias tsis muaj lub teeb liab, ntsuas qhov hloov pauv ntawm qhov hloov pauv kom paub tseeb tias nws ua haujlwm tau zoo. Feem ntau, nws yog kev coj ua zoo los ntsuas lub teeb liab hla txhua qhov khoom siv kom pom qhov twg hauv Circuit Court ua tsis tiav.
