Hom kev hloov pauv tau muab rau saum toj no muaj qhov sib piv ntawm 115: 6.3, uas yog me ntsis tawm ntawm 115: 6 hloov pauv kuv tau siv. Txawm li cas los xij, qhov sib txawv ntawm qhov sib txawv hauv qhov hluav taws xob tso tawm yuav tsis ua rau muaj kev hloov pauv loj hauv cov txiaj ntsig thiab yuav tsis tshuab lub diodes lossis cov resistor. Tsis tas li, zoo nkauj txhua yam loj ntawm diodes yuav tsum sib xws nrog txoj haujlwm no, tab sis nco ntsoov koj tshuaj xyuas tias qhov siab tshaj qhov rov qab hluav taws xob ntau dua li qhov tso tawm ntawm lub tshuab hluav taws xob.

*Rau Cov Neeg Nyob Hauv Lub Tebchaws uas Siv 220V AC

Qhov hluav taws xob tso tawm los ntawm kev hloov pauv yuav ob npaug, tab sis qhov ntawd yuav tsis tshuab cov khoom siv yog tias koj tau txais hom raug. Txwv tsis pub, koj tuaj yeem ua ob npaug ntawm qhov tsis kam ntawm tus tiv thaiv lossis siv lub tshuab hloov pauv uas muaj qhov sib piv piv ze rau 220: 6.

Kauj ruam 1: Circuit Court

Koj tuaj yeem siv cov phiaj xwm muab hauv cov duab (P1) ua cov lus qhia los tsim cov phiaj xwm. Lossis koj tuaj yeem tsim lub Circuit Court siv cov duab ntawm Circuit uas kuv tau ua rau ntawm lub khob cij (P2 thiab P3). Nco ntsoov tias lub tshuab hluav taws xob tau tsom mus rau hauv ib txoj hauv kev uas nws cov ceg ntev (ceg zoo) tau txuas rau sab saum toj (lub qhov G4 ntawm kuv lub khob cij). Kev taw qhia ntawm tus tiv thaiv tsis muaj teeb meem. Ib daim duab uas qhia txog kev ntws tam sim no hauv diode. Txheeb nws hauv cov duab (P4). Lub tshuab hluav taws xob txuas hluav taws xob tag nrho yuav tsis ua haujlwm tshwj tsis yog lub diodes nyob hauv txoj kev yog. Hauv kuv qhov teeb tsa, lawv txhua tus tau hais qhia rau sab xis, yog li koj tuaj yeem tshawb xyuas sai yog tias txhua lub diode nyob hauv qhov kev qhia raug.

Nov yog qhov txuas rau kev sib tham sib simulation ntawm lub voj voog no:

Vam tias qhov kev sim sib tham sib tham pab koj nkag siab txog qhov kev ua haujlwm no li cas.

*Nov yog qhov txuas rau cov lus qhia yuav siv lub khob cij li cas yog tias koj tsis paub nws.

Kauj Ruam 2: (Tsis teb los tau) Siv Lub Tshuab Hluav Taws Xob Ua Haujlwm thiab Oscilloscope los Ntsuam Xyuas

Ua ntej ntsaws rau hauv lub tshuab hluav taws xob, koj tuaj yeem sim koj lub tshuab hluav taws xob txuas hluav taws xob tag nrho los ntawm kev txuas nws mus rau lub tshuab hluav taws xob muaj nuj nqi thiab saib ntawm qhov nthwv dej ntawm qhov ntsuas hluav taws xob siv lub oscilloscope.

1. Txuas lub oscilloscope: Kev sojntsuam yuav tsum txuas nrog rau sab xis ntawm tus tiv thaiv thiab av los ntawm kev txuas nws lub hauv paus sojntsuam mus rau sab laug ntawm tus tiv thaiv ib yam li qhia hauv daim duab.

2. Daim duab uas kuv muab (P1) qhia txoj hauv kev uas koj yuav tsum txuas lub cuab yeej muaj lub khob cij tig 90 degrees raws lub moos. Nco ntsoov tias txhua yam tau txuas nrog kom raug ua ntej tig lub tshuab hluav taws xob ua haujlwm.

3. Kho koj lub tshuab hluav taws xob kom nws tsim cov sinusoidal waveform nrog lub hauv paus-txhais-xwmfab voltage ntawm 6V (koj tuaj yeem ntsuas qhov no nrog lub ntsuas cua yog tias tsim nyog).

Nco ntsoov tias cov xov hlau zoo nkag mus rau txoj kab hluav taws xob liab ntawm lub khob cij (qhov twg muaj kab liab), thiab hauv av (tsis zoo) xaim mus rau hauv txoj kab hluav taws xob xiav (qhov twg muaj kab xiav).

Yog tias cov nthwv dej koj pom zoo ib yam rau qhov kuv tau muab (P2), mus rau kauj ruam tom ntej.

Cov lus qhia daws teeb meem:

1. Yog tias cov duab yoj ntawm lub oscilloscope tsis zoo ib yam li kuv, sim ntsuas nws cov ntsug thiab kab rov tav.
2. Nco ntsoov tias tsis muaj cov xov hlau sib chwv ib leeg thaum ua qhov ntsuas.
3. Yog tias tsis muaj qhov ntsuas hluav taws xob, sim rov txuas dua ntawm cov khoom siv thiab lub khob cij raws li nws yuav yog qhov koj muaj lub Circuit Court uas qhib tsis tau
4. Txuas mus rau phau ntawv qhia yuav siv lub oscilloscope li cas:
5. Txuas mus rau phau ntawv qhia yuav siv lub tshuab hluav taws xob li cas:

Kauj Ruam 3: Txuas Breadboard rau Transformer

Txuas tus hloov pauv thiab oscilloscope nrog cov lus qhia hauv ntu yav dhau los thaum siv cov duab hais hauv ntu no. Daim ntawv ceeb toom tias thaum txuas lub khob cij rau lub tshuab hloov pauv, sab zoo/tsis zoo tsis muaj teeb meem txij li tam sim no hloov pauv. Txoj hauv kev uas koj txuas lub khob cij rau lub oscilloscope tseem zoo ib yam.

Kauj Ruam 4: Cov Ntsiab Lus Los Ntawm Oscilloscope

Qhov Voltage hla tus tiv thaiv (load voltage) yuav tsum sib txawv ntawm 5V thiab 6V, nrog lub sijhawm ntawm 8.33 ms.

Vim li cas lub sijhawm 8.33 ms?

Qhov zaus ntawm cov txheej txheem yuav tsum yog ob npaug ntawm cov khoom siv hluav taws xob, uas muaj zaus ntawm 60 Hz. Qhov laj thawj yog tias tag nrho yoj choj choj rectifier tsis muaj lub capacitor yeej siv qhov tseem ceeb ntawm thawj sinusoidal waveform, yog li cov yoj rov ua dua nws tus kheej txhua ib nrab lub sijhawm. Yog li qhov zaus ob npaug thiab lub sijhawm ib nrab. 1/(2*60) = 0.00833s = 8.33ms.

Kauj Ruam 5: Piav Qhia

Hauv Circuit no, 120 Vpeak-to-peak AC voltage tau hloov pauv mus rau 6 V nrog lub tshuab hloov pauv. Yog li tam sim no muaj txiaj ntsig peb muaj 6V AC fais fab mov. 4 diodes tau teeb tsa nyob rau hauv ib txoj kev uas txawm tias cov tswv yim tam sim no taug kev mus rau ob qho tom ntej thiab rov qab qhia, cov zis tam sim no los ntawm pab pawg ntawm diodes taug kev tsuas yog hauv ib qho kev qhia, tab sis qhov hluav taws xob tsis tas li vim tias qhov hluav taws xob nkag yog sinusoidal (uas txhais tau tias nws oscillates zoo li sine lossis cosine yoj). Qhov hluav taws xob tso tawm nrog kev hwm rau lub sijhawm thaum tsis muaj lub tshuab txuas nrog zoo li P2 (t-axis tsis ntsuas).

Cov diodes tuaj yeem ua qhov no vim tias lawv tsuas tso cai rau tam sim no ntws hauv ib qho kev qhia (feem ntau).

Lub tshuab hluav taws xob ua haujlwm khaws cov hluav taws xob hluav taws xob thiab tso tawm thaum lub zog tam sim no qis rau ntawm sab nraub qaum. Cov cuab yeej ntawm lub capacitor haum rau ua kom du tawm qhov hluav taws xob tso tawm.

Koj tuaj yeem ua tibzoo saib ntawm kev sim sib tham rau qhov pom kev pom ntau npaum li cas ntawm cov dej ntws tam sim no:
