Izixhobo kunye yokusebenza siseko diode kwebhulorho rectifier yesekethe

Alternating current ombane atshintshelwe DC idaleka ngokusebenzisa leesekethe ezizodwa elektroniki - kwo diode. Diode ibhulorho rectifier yesekethe yahlulwe iinguqulelo ezimbini:-isigaba enye ontlantlu-ntathu.

Xa rectifier element engundoqo a diode. Ngokwemo, oko imbasa chip semiconductor kunye imimandla conductivity ezimbini ezahlukeneyo. A feature ingxelo unilateral umsinga wombane, kuxhomekeke indlela kwemali.

Ubume kunye umsebenzi diode rectifier ngokusekelwe iimpawu semiconductor PN lenguqu phakathi imimandla. ukuxhathisa yayo ixhomekeke ezichaseneyo le ombane lwangaphandle. Kwenye imeko, nto inkulu, ngamanye - kancinci.

I-single-Isigaba diode ibhulorho

Xa igalelo - AC ombane sine ngumtshangatshangiso ngamnye kumjikelo isiqingatha yangoku udlula iperi ilight kunye nezinye ivaliwe. Ngenxa yoko, umphathi wesekethe imveliso wambumba umntu diode kwebhulorho rectifier yama- ombane ukuba amaza izihlandlo ezimbini ezinkulu kuno kwi ugwebu.

Isigaba ezintathu-ibhulorho yesekethe

Le wesekethe isebenzisa diode rectifiers isiqingatha-kwebhulorho. Le ombane yemveliso ifunyenwe kunye pulsations ezincinane.

Indlela uwugudise yama- kwi nokolula igunya?

Umgangatho ombane bulungiswe lehla nge ukwanda pulsation yayo. Ukunciphisa oko, isicelo izinto, baba amandla xa kubonelelwa ukusuka rectifier kususwa phezu ukupheliswa lokufaka yayo.

Kulo mzobo, a rectifier diode ibhulorho kunye capacitor enxulumene ngaxeshanye kunye nomthwalo yokugqibela. amandla ayo yokugcina lukhethiwe ngokuxhomekeke umthwalo yangoku. Xa kusetyenziswa ukubetha le capacitor lo ukutshaja. Phakathi pulses (xa bengengabo), unikwa umthwalo ombane.

Ngenxa ukwenziwa mpuluswa filter imveliso ombane igcine neenkqubo ixabiso ngexabiso awo bulungiswe.

Ombane efanelekileyo xa imveliso lemifanekiso ayikwazi zingafumaneka ngenxa wokuqhuba capacitor phakathi pulses. Ngokuqhelekileyo, ezi pulsations avumeleke. Bangakwazi inokuncitshiswa ngokwandisa capacitance le capacitor.

Xa esebenzisa elona inductor mpuluswa, elidityaniswe kuyo series kunye nomthwalo. Umphathi wesekethe filter edityanisiweyo luquka inductors kunye capacitors.

Ukwakhiwa kwebhulorho diode

Icebo ibhulorho elula kwenziwa nge ilight ezahlukeneyo azikhuli. Ishishini ivelisa izakhiwo monolithic ezincinane ngobukhulu kwaye sitshiphu. Ukongeza, ukuba ifaniswe ilight ezineempawu ezifanayo, evumela ukuba basebenze kunye nobushushu efanayo. Oku kwandisa ukuthembeka wesekethe diode ibhulorho rectifier.

Buhle diode kwebhulorho eziqalelo ngamnye kukukwazi ukulungisa, xa omnye wabo lwaphela. Kwakhona ibandla kufuneka kutshintshwa ngokupheleleyo. Iziphene kulo zinqabile, kuba izinto ifaniswe ngokufanelekileyo.

rectifiers Power

Devices ephelisa nosebenzela elikhulu, ngokokuqhelekileyo anikwe amandla 220 V. izixhobo ngqo bangabi nayo, ekubeni ombane ezifunekayo iziphaluka elektroniki elincinane, kukho yangoku - rhoqo. Emva koko sebenzisa AC zombini.

Ombane base- yi nesiguquli, nayo leyo idala bodwa galvanic phakathi imixokelelwane isondlo zaseprayimari nasesekondari. Oku kunciphisa amathuba ugesi kunye ukhuselwe izixhobo xa elifutshane kwisiphaluka wesekethe.

amaqhoshana Modern zisebenza kwiimeko ezininzi le wesekethe transformerless lula ngaphandle ikheswa galvanic, apho amandla agqithisileyo lilo capacitor.

Driving le diode ibhulorho volts 12: imfundo kunye nebandla

Umbane lineemodyuli amabini, apho lokuqala - linyathelo-phantsi sombane, kwaye eyesibini - ibhulorho diode esiguqula olunye uhlobo ombane ukuya kwenye.

Wakhethwa transformer efanelekileyo. Primary oyinkampani ukunye ngumhloli. ukuqina kwayo kufuneka ibe ngoyena mkhulu. Ngu ukuqhubeka esifunekayo multimeter ke imo ukumelana womlinganiselo. Ngoko kukho ezinye izibini neempawu ezenziwe.

Inikezelwa primary ngokubhijela 220 V. ke tester iguqulelwe i imo womlinganiselo ifildi ombane kwaye umlinganiselo ombane kwelinye engathi. Khetha V. elinye okanye bayotywe 10 Kubalulekile ukuba ombane-12 V, ekubeni lokucoca capacitive emva kokuba linyuke nge-18%.

Le transformer siyahlengahlengiswa ngamandla ofunekayo, ngoko ke isitokhwe kuthathwa yi-25%.

4 diode ezijijekileyo kwi ibhulorho diode neliphela propaivayutsya. Ngoko ke wesekethe elidityaniswe, phezu capacitor output elidityaniswe 25 V no 2200 MF (electrolyte) kunye zaqinisekiswa msebenzi.

Transformerless ukujikeleza + volts diode ibhulorho rectifier 24

Ekusebenzeni engahlawulwayo esisetyenziswa ngokubanzi ephantsi-power umbane ngaphandle abaguquli.

220 Power bonelelo kubonelelwa ngalo C1 zokulinganisa capacitor. Le rectifier iqulathe ode VD1, VD2 kunye Zener ode VD3, VD4. Ukuphelisa kwama ezikhoyo kwebhulorho anxibelelanisa capacitor igunya kuthotho kunye resistor umda ngoku umiselwe ukungawi 50-100 ohms. Ukuze ikhulule capacitor xa kwaphulwa wesiphaluka, elidityaniswe ngokunxuseneyo noko 150-300 resistor kohm.

Umphathi wesekethe yemveliso imiselwe capacitor mpuluswa a capacitance ka-2000 PF.

Unxibelelwano ukungabikho galvanic kudala ingozi ugesi.

isicelo

Izicelo ze kwebhulorho diode libanzi kakhulu kwaye zahlukene:

• izibane (LED kunye izibane ezibengezelayo);
• izixhobo wekhadi umbane;
• umbane iiyunithi kwezixhobo zombane;
• supply amandla ezoshishino, ulawulo kokuxhuma.

Indlela ukukhetha diode yokwenza ibhulorho diode?

Indlela yokukhetha le ombane kwaye ngoku apho diode olo ebilayo. In ngqo ukufakwa kwaso uwa ombane malunga 0.6 V, njengoko ine- ukuxhathisa lwangaphakathi. Le ombane reverse ukuba diode ukumelana ngaphandle kokufaka imo yokuwa thermal kunye zombane, uye umda ethile. Ukuba yenzelwe 220 V, kufuneka stock angekho ngaphantsi kwe-25%. Kodwa ke kubhetele ukuthatha inkulu ngokwaneleyo ukukhusela ngokuchasene ngengozi amandla-line ngamandla.

Lwangoku kwakhona kususwa kulo myezo. Ukuba kuyimfuneko, inika kwiradiyetha okupholisa.

Kuba ukukhetha lasekunene reference itafile ezi ilight kunye kwo diode.

Manufacturers Iibhulorho diode

Phakathi izinto ukukhanyisa stand rectifiers series 1N4007 kunye MS250 elalenziwe Diotec. Ezi nkundla ke zenzelwe ukuba yombane ukuya ku-1000 V. Kwimeko yokuqala, wesiphaluka diode ibhulorho iqulathe ilight ezine amalungiselelo ebhodini wesiphaluka, yaye owesibini ubekwa kwindibano compact. Nangona series 1N4007 ethembeke ukusebenza, ibandla MS250 igcina ubunzima kunye umzila. Ngaphandle koku, uthotho lwe 1N4007 imfuno kuhlala phezulu, njengoko ixabiso liye lehla kakhulu kangangokuba uzimisele kakhulu ixabiso zezigqibo zezobhedu.

Manufacturing netheknoloji MS iibhulorho series diode kuyaqhubeka. Ngoku zonke 4 ngembonakalo yikristale kwebhulorho zifakwa kunye, nto leyo eyandisa ukuxhathisa yayo ubushushu ngenxa parameters efanayo.

Ukuthembeka rectifier liyancipha olwandayo lobushushu ngumsindo. Le ngxaki isonjululwe luthotho isixhobo B250S2A ibalwa yangoku 2.3 A no 0.7 A transmissive kwi 125 ° C.

abavelisi abaninzi ukuthenga ode, ebezikuyo rectifiers ukulungele. Le nkampani ukwenza yonke imveliso Diotec, ukususela eyimveliso ziikristale aqoqe package.

Enye inkampani emhlabeni phambili - IRF - anazo ubugcisa ezizodwa ukunciphisa ubungakanani iindawo, ukuphucula transfer ubushushu, ukwandisa ukwanela zobugcisa semiconductor. Yena nguye kuphela evelisa amacandelo wonke umjikelo conversion amandla.

isiphelo

Isekethi rectifier diode ibhulorho isetyenziswa kuzo zonke izixhobo ze-elektroniki. Ukuba isicelo full-wave rectifier, ogama iimpawu zingcono kakhulu kunokuba elinye ithuba. Khangela nasiphi na kubo kuphindwe prozvoniv diode nganye.
