Kusebenza ngokupheleleyo-wave rectifier, nendlela

Rectifier ebizwa converters kagesi, ezo semiconductor okanye esinye isixhobo se-elektroniki lokuguqula igalelo AC amandla DC kwimveliso. Wave rectifier eyakhelwe phezu isiqingatha-ibhulorho okanye yesekethe ibhulorho, ukuyilwa eneenkcukacha apho siza kuqwalasela.

Kakuhle eli isixhobo kunye rectifier ngokupheleleyo-wave

Uninzi lwezi zixhobo kudala ombane oluthambileyo yama- nzi. Lungisani pulsation, sebenzisa izihluzi ezizodwa.
Ukuphucula rectifier iparameters eziyimfuneko ukubonelela ukuhamba ngoku ukuba zombini isiqingatha nexesha le ombane igalelo. Ukulungiselela le njongo, zimbini iintlobo kwiisekethe basebenzisa i ukulungisa nesiqingatha-yomtshangatshangiso, esebenza antiphase kwaye synchronism kunye umthwalo eqhelekileyo.

Nale ukufakwa kufuna mthombo ezimbini ombane zaseprayimari, nto leyo eya kuba kwincopho eqhelekileyo. Esi sikimu ubizwa ngokuba "full-wave rectifier kunye ngongoma phakathi." Ixabiso avareji ye ombane kule resistors umthwalo kwi elizeleyo wave nokulungisa iziphawuli uya kudlula kabini wesiphaluka isiqingatha-ngumtshangatshangiso.

Kufuneka kuqatshelwe ukuba izikim dvuhpolupeiodnoy bako umbindi, inazo izinto zayo ezimbi. Xa ngoku eyipasile diode enye kwincopho malunga ombane umva kwisigaba ufikelela ezona kabini ombane igalelo, yintoni kufuneka kukhunjulwe ukukhetha ode ngenxa rectifier.

Kule nkalo, cinga isekethi epheleleyo-wave rectifier eneenkcukacha ngakumbi ukuba isiqulatho yesinyithi kokuba enkulu esebenzayo elinganayo ukumelana lwangaphakathi. Oku kukhokelela kubukho ilahleko enkulu neyayanyaniswa zokufudumeza ebalulekileyo transformer.

Xa ngolwakhiwo isekethe esinjalo capacitor mpuluswa, kubalulekile ukuqwalasela ukuba ombane ifildi womlinganiselo kusoloko iinqobo ezisemgangathweni zokusebenza, ezo zincinane kakhulu ngaphezu awo ubuninzi. Xa kungekho umthwalo capacitor le ombane bulungiswe isoloko awo ngokulinganayo. Oku kuthetha ukuba rectifier ngokupheleleyo-ngumtshangatshangiso kokuba ezi-ifildi sangoku capacitor 12, xa kungekho umthwalo ufumana amandla ombane ayi-17 V. Ukusuka oku, siyakwazi ukubona ukuba phantsi komthwalo le ombane kuyalungiswa unciphisa, kodwa abe ngaphantsi kwe yezahlukileyo ezikhoyo ombane ngoku yaye ziza kumiselwa umthamo a capacitor emlungisa.

circuit rectifier elolu hlobo luchazwe ngolu hlobo lulandelayo. Ukuze ukucinezela ukungenela primary transformer kwemicimbi inxibelelene lokucoca, nto leyo ubunjwe capacitors ezimbini kunye kwindawo eqhotyoshelweyo embindini ukuya emhlabeni. Kuyafuneka ukuba unipolar, nokunciphisa uhlahlelo okuba le ombane rated kunqula 200 V.

Ngokuqhelekileyo, iswitshi kuzakucwangcisa ekondensa, kuyimfuneko ukuba ithintele ombane mbane ngexesha ukusebenza kwi capacitors rectifier. Fullwave rectifier transformer a yesibini siya emininzi enempompo iziko, kodwa kule imveliso yesekethe kwebhulorho ayikho imfuneko. Isihluzi kuba rectifier kunye capacitor ezimbini resistor series. Nangona kunjalo, izinga eliphantsi yama- eyamkelekileyo ongeze omnye capacitor output kunye resistor.

Ekubeni kwiimatshini zombane usebenza ngokuvumelana kumgaqo ukuyilungisa, rectifiers ombane kunye inverter iintlobo ezimbini oomatshini zombane. Wabiza isixhobo inverter uguqula DC ombane AC.
