Kev kho dua tshiab yog txheej txheem ntawm kev hloov pauv hloov pauv tam sim no mus rau qhov ncaj qha tam sim no.

Kauj Ruam 1: Sib Diagram ntawm Txoj Haujlwm

Kev kho dua tshiab yog txheej txheem ntawm kev hloov pauv hloov pauv tam sim no mus rau qhov ncaj qha tam sim no. Txhua tus thiab txhua lub zog siv hluav taws xob offline muaj qhov kho qhov thaiv uas ib txwm hloov pauv hloov tam sim no mus rau qhov ncaj qha tam sim no. Lub rectifier block yog ib qho nce mus rau qhov hluav taws xob siab DC lossis txawm nqis los ntawm AC phab ntsa qhov chaw txais khoom mus rau qhov qis DC. Tsis tas li ntawd, cov txheej txheem tau suav nrog cov ntxaij lim dej uas ua rau DC hloov pauv tau yooj yim. Txoj haujlwm no hais txog kev hloov pauv ntawm qhov hloov pauv tam sim no mus rau tam sim no nrog thiab tsis muaj lub lim. Txawm li cas los xij, lub rectifier siv yog puv nthwv dej rectifier. Cov hauv qab no yog daim duab sib dhos ntawm txoj haujlwm.

Kauj Ruam 2: Txoj Kev Rectification

Muaj ob txoj hauv kev yooj yim kom tau txais kev kho kom raug. Ob leeg yog raws li hauv qab no:

1. Center Tapped Full Wave Rectification Daim duab qhia chaw ntawm lub chaw tapped tag nrho yoj kev kho yog raws li hauv qab no.

2. Choj Rectification siv Plaub Diodes

Thaum ob qho ntawm cov ceg ntoo ntawm kab hluav taws xob txuas nrog rau ceg thib peb tau tsim lub voj thiab hu ua kev teeb tsa ntawm tus choj txuas. Hauv ob qho txheej txheem no ntawm kev kho tus choj, cov txheej txheem nyiam dua yog Choj kho qhov muag siv diodes, vim tias ob lub diodes uas xav tau kev siv lub chaw nruab nrab tapped transformer uas tsis ntseeg tau rau txheej txheem kho. Ntxiv mus, pob diode tau npaj muaj nyob rau hauv daim ntawv ntawm pob, xws li GBJ1504, DB102, thiab KBU1001 thiab lwm yam.

Yam Yuav Tsum Ua Cov khoom siv xav tau raws li hauv qab no. 1. Transformer (220V/15V AC nqis qis)

2. Resistors

3. MIC RB 156

4. Capacitors

5. Diode (IN4007)

6. Mov ci Board

7. Txuas cov xov hlau

8. DMM (Digital Multi Meter)

Lus ceeb toom ceev faj:

Hauv qhov haujlwm no kom muaj RMS qhov hluav taws xob ntawm 15V, nws qhov siab tshaj yuav nce siab dua 21V. Yog li, cov khoom siv yuav tsum muaj peev xwm txhawb nqa 25V lossis siab dua.

Kev ua haujlwm ntawm Circuit:

Kev siv cov kauj ruam qis hloov pauv tau suav nrog uas yog suav nrog cov thawj thiab theem thib ob cov cua uas raug mob hla cov tub ntxhais txheej hlau. Qhov tig ntawm thawj qhov cua yuav tsum siab dua li qhov tig ntawm qhov thib ob winding. Txhua qhov ntawm cov cua no tau ua raws li qhov sib cais inductors thiab thaum thawj qhov winding tau muab nrog qhov hloov pauv tam sim no qhov chaw winding tau zoo siab uas tig rov tsim cov flux. Whereas qhov thib ob winding tau ntsib qhov hloov pauv tau tsim los ntawm thawj qhov kev sib tw induction thiab EMF hla qhov thib ob winding. EMF raug ntxias yog tom qab ntawd ntws hla qhov hluav taws xob sab nraud uas txuas nrog nws. Qhov inductance ntawm cov cua sib xyaw ua ke nrog qhov sib piv sib piv tau txiav txim siab tus nqi ntawm cov dej ntws tau tsim los ntawm thawj qhov kev sib tw thiab EMF ua rau hauv qhov thib ob winding.

Kauj Ruam 3: Daim duab Circuit Court yooj yim

Nram qab no yog daim duab qhia chaw yooj yim siv hauv software.

Txoj Haujlwm Ua Haujlwm Rau txoj haujlwm, txiav txim siab hloov pauv qhov hluav taws xob tam sim no uas muaj qhov qis dua qis dua li 15V RMS uas yuav luag 21V qhov siab tshaj plaws rau qhov siab tshaj plaws tau raug kho rau qhov ncaj qha tam sim no siv tus choj txuas. Cov nthwv dej ntawm kev hloov pauv tam sim no tuaj yeem faib ua qhov ib nrab mus rau qhov zoo thiab tsis zoo. Nov yog qhov tam sim no thiab qhov ntsuas hluav taws xob tau ntsuas los ntawm digital multi meter (DMM) hauv RMS qhov tseem ceeb. Cov hauv qab no yog qhov Circuit Court simulated rau qhov project.

Thaum qhov zoo ib nrab ntawm kev hloov pauv tam sim no dhau los ntawm diodes D2 thiab D3 yuav ua lossis ua rau muaj kev tsis ncaj ncees, thaum lub diodes D1, thiab D4 yuav ua thaum qhov tsis zoo ib nrab yuav dhau los ntawm Circuit Court. Yog li ntawd, thaum ob qho tib si ntawm ib nrab mus rau ib nrab diodes yuav ua. Waveform ntawm cov zis tuaj yeem tsim tawm raws li hauv qab no.

Cov yoj yoj hauv cov xim liab hauv daim duab saum toj no yog qhov hloov pauv tam sim no thaum lub nthwv dej hauv cov xim ntsuab yog qhov ncaj qha tam sim no raug kho los ntawm choj rectifiers.

Kev tsim tawm nrog kev siv Capacitors

Txhawm rau txo qhov cuam tshuam ripple hauv cov yoj yoj lossis ua kom cov nthwv dej txuas ntxiv mus peb yuav tsum ntxiv cov lim dej lim ntawm nws cov zis. Kev ua haujlwm yooj yim ntawm lub capacitor yog thaum nws tau siv nyob rau hauv sib npaug rau lub load rau tswj lub qhov hluav taws xob tas li ntawm nws cov zis. Yog li no, qhov no yuav txo qhov ripples hauv qhov tsim tawm ntawm Circuit.

Kauj Ruam 4: Siv 1uF Capacitor rau Lim

Thaum 1uF capacitor tau siv nyob rau hauv Circuit Court hla kev thauj khoom, muaj qhov hloov pauv tseem ceeb hauv kev tsim tawm ntawm Circuit Court ua kom du thiab zoo ib yam. Nram qab no yog daim duab qhia chaw yooj yim ntawm cov txheej txheem.

Cov zis tau raug lim los ntawm 1uF capacitor uas yog dampening nthwv dej tsuas yog qee yam raws li lub zog cia ntawm lub capacitor tsawg dua 1uF. Cov hauv qab no yog qhov tshwm sim simulation ntawm daim duab qhia chaw.

Raws li lub ripple tseem tuaj yeem pom hauv qhov tsim tawm ntawm Circuit Court yog li los ntawm kev hloov pauv qhov tseem ceeb ntawm lub capacitor, ripples tuaj yeem tshem tawm tau yooj yim. Cov hauv qab no yog cov txiaj ntsig rau lub peev xwm ntawm -1uF (Green), -4.7uF (Blue), -10uF (Mustard Green), thiab -47uF (Dark Green).

Kev ua haujlwm hauv Circuit nrog Capacitor thiab xam Ripple Factor Thaum lub sijhawm tsis zoo thiab ib nrab ib nrab mus, cov diodes tau sib koom ua ke nws tus kheej ua ntej lossis thim rov qab kev tsis ncaj ncees thiab lub capacitor tau txais ob qho tib si them thiab tso tawm dua. Lub sijhawm luv thaum lub zog hluav taws xob tam sim ntawd thaum lub zog khaws cia siab dua qhov hluav taws xob tam sim ntawd, lub tshuab hluav taws xob tom qab ntawd muab lub zog khaws cia. Yog li ntawd, ntau dua yog lub peev xwm khaws cia ntawm lub capacitor, qhov tsawg dua yuav yog nws cov txiaj ntsig ripple hauv cov zis waveforms. Qhov ripple tuaj yeem xam raws li hauv qab no.

Qhov ripple tau raug them los ntawm qhov muaj txiaj ntsig siab dua ntawm lub capacitor. Yog li ntawd, qhov ua tau zoo ntawm kev hloov pauv tag nrho yoj choj txuas yuav luag 80 feem pua uas yog ob npaug ntawm ib nrab yoj rectifier.
