Mabda 'qalab iyo qalliinka Bannaanka rectifier buundada diode a

Talantaalli ah qulqul koranto waa diinta DC pulsed iyadoo la adeegsanayo wareeggeedii electronic gaar ah - buundooyinka diode. Diode circuit rectifier buundada u qaybsan yahay laba nooc, mid-waji iyo saddex waji.

In element ugu weyn rectifier waa diode ah. Qaab ahaan, waa waslad khafiifa oo chip Semiconductor leh laba qaybood conductivity kala duwan. feature A waa mawduuc geesood ah ee koronto, taas oo ku xidhan jihada socodka.

Dhismaha iyo shaqada diode rectifier ku salaysan muuqaalada kala guurka pn Semiconductor dhexeeya goobaha ay. Its iska caabin ah ku xiran tahay polarity ee danab dibadda. In mid ka mid ah kiis, waa weyn yahay, in si kale - wax yar.

The buundada diode-hal waji

Marka la gelin ah - AC danab Culumida la ruxruxo ee wareegga kasta nus ka mid ah hadda ka maraa labo ka mid ah dioska- oo kale la xiray. Sidaas darteed, circuit wax soo saarka la aasaasay of danab Cabidkariin diode rectifier buundo isagoo inta jeer laba jeer ka badan ee gacanka.

The circuit buundada saddex waji

circuit wuxuu isticmaalaa diode rectifiers bar-buundada. danab saarka ayaa la helay iyadoo pulsations yar.

Sidee loo simi baxay Cabidkariin ee awoodda toosinta?

Tayada danab ku hagaajin hoos u la kordhiyo ay pulsation. Si aad u yareeyo, codsan xubno, aruursaday tamarta marka ka rectifier ka bariyeelay dul joojinta ay fayl bixisey.

In jaantuska, rectifier buundada diode la capacitor ah oo ku xiran in barbar load ee la soo dhaafay. awoodda ay kaydinta la doorto ku xiran load hadda. Marka aad codsanayso garaaca wadnaha capacitor waxaa ku amraya. Inta u dhaxaysa karsado (marka aan la), waxaa la siiyey load danab a.

Sidaas darteed of danab yeeesha saarka filter uu noqdo mid weyn iyo habab qiimaha qiimaha Ilodanimada saxo.

danab An fiican ee wax soo saarka ee filter ma laga heli karaa sabab u dheecaan ah ee capacitor u dhexeeya karsado. Sida caadiga ah, pulsations kuwanu waa la ogolaan karo. Waxay la yareyn karaa iyadoo la kordhinayo capacitance ee capacitor ah.

Haddii inductor yeeesha loo isticmaalo, waxa uu ku xiran yahay ee taxanahan la load ah. The circuit filter isku daro waxaa ka mid ah inductors iyo capacitors.

Dhismaha buundada diode ah

The buundada qalab fudud loo sameeyaa via adhesions dioska- oo kala duwan. warshadaha ayaa soo saarta dhismayaasha mabda'a ah in ka yar ee size iyo jaban. Intaa waxaa dheer, waxay kulan dioska- oo leh sifooyin la mid ah, in u ogolaanaya inay ka kulayl isla shaqeeyaan. Tani waxay kordhisaa isku halaynta of circuit diode rectifier buundada.

Faa'iidada ee buundada diode oo ka mid ah xubno qofka waa awooda si ay u cusboonaysiiyaan, markii mid ka mid ah ku guuldareysto. shirka ayaa sidoo kale waxa uu leeyahay in la gabi ahaanba bedelay. Unu waxa ku jira waa dhif iyo naadir, maxaa yeelay xubno ka yihiin si fiican isku aadiyo.

rectifiers Power

Qalabka in baabbi'in hadda u badan, caadi ahaan waxaa ku shaqeeya by 220 V. qalabka Direct aan la xiran, tan iyo danab loo baahan yahay ee wareeggeedii electronic waa yar yahay, hadda ah - si joogto ah. Markaas isticmaalaan adabtarada AC ah.

Danab hoos by transformer ah, kaas oo sidoo kale abuuri go'doon ah galvanic dhexeeya silsilado feed hoose iyo kuwa sare. Tani waxa ay yaraynaysaa halista ah ee shoog koronto iyo in laga ilaaliyo by qalab markii a-circuit gaaban ee Bannaanka.

adapters Modern shaqeeyaan kiisaska intooda badan ku soo wareegi jiray fududeeyey transformerless aan go'doomin galvanic, kuna waari dhexdeeda xoogga xad-dhaaf ah u nuugo by capacitor ah.

Wadista buundada diode 12 volts: edbinta iyo ururkii

korontada wuxuu ka kooban yahay laba qaybood, halkaas oo marka hore ka - transformer tallaabo-hoos ah, iyo tan labaad - buundada diode in badasha hal nooc oo danab si kale ah.

Soo xulay transformer ku haboon. The hoose loogu fuuli jiray waa la ahaatid. Its iska caabin ah waa in ay ahaadaan ugu weyn. By sii shishaysa multimeter la doonayo waa in hab cabbirka iska caabin ah. Markaas waxaa jira lamaane kale iyo xariiqyada sameeyey.

Ma bixisey si hoose loogu fuuli jiray 220 V. Markaasaa ahaatid la turjumay hab ah cabbirka danab talantaalli oo cabiraya danab ku windings kale. Dooro mid ama ka ambadeen 10 V. Waxaa muhiim ah in danab ahaa 12 V, tan iyo filter ah capacitive ka dib waxaa kor u kacay 18%.

transformer waxaa loogu habeeyaa awoodda la doonayo, ka dibna stock loo qaado 25%.

4 diode qaloocin in buundada diode iyo dhamaado propaivayutsya. Markaas wareeg ee ku xiran yahay, on capacitor wax soo saarka ee ku xiran 25 V iyo 2200-Ji (elektrolytka) iyo xaqiijin in hawlgalka.

circuit Transformerless ah diode rectifier buundada 24 volts

In dhaqanka hiwaayadda si ballaaran loo isticmaalo korontada low-awood aan gudbiyeyaasha.

Power sahayda 220 waxaa bixisey dhex C1 capacitor waaya'aragnimo ka. rectifier wuxuu ka kooban yahay dioska- VD1, VD2 iyo Zener dioska- VD3, VD4. Si aad u baabi'iyo mawjadahaa hadda marayo buundada isku xirta capacitor xoogga ee taxanahan la resistor a yareysey hadda lagu wadaa iska caabin ah 50-100 ohms. Si loo guto capacitor marka circuit jebiyey, ku xiran ee isku midka ah darina 150-300 resistor kohm.

circuit saarka ayaa la filayaa capacitor yeeesha capacitance a of 2000 PF.

The isgaarsiinta galvanic la'aanta abuuraa khatarta ah ee lama filaanka aheyd korontada.

codsiga

Codsiyada buundada diode ah waa mid aad u ballaaran oo kala duwan:

• nalalka (LED iyo nalalka dhaadheer);
• qalabka la isticimaalay korontada,
• unugyada korontada ee qalabka elektarooniga ah,
• korontada warshadaha, gacanta oo saxan.

Sida loo doorto diode ah samaynta buundada diode ah?

Shuruudaha ugu muhiimsan doorashada waa danab iyo haatan oo diode uusan u kululaatid. In mid noqoshada toos ah ku dul dhaco danab ee ku saabsan 0.6 V, sida uu leeyahay iska caabin gudaha ah. danab dambe in diode ka hor joogsadaa aan galaya hab burburka kaamerada iyo korontada, ayaa xad go'an. Haddii ay waxaa loogu talagalay 220 V, waxa ay qaadataa stock aan ka yarayn 25%. Laakiin waxa fiican in aad u weyn oo ku filan si looga hortago shil awood-line roobku qaado.

Hadda waxaa sidoo kale laga soo qaatay juunyeerka. Haddii loo baahdo, waxa uu siiyaa hiitarka a qaboojinta.

Wixii doorashada saxda ah ee miiska tixraaca waa dioska- iyo buundooyinka diode.

Soo-saareyaasha buundooyinka diode

Waxaa ka mid ah waxyaalaha aasaaska u ah nalalka taagan 1N4007 rectifiers taxane iyo MS250 macmalay by Diotec. Waxay waxaa loogu talagalay voltages ilaa 1000 V. In kiiska ugu horeysay, circuit buundada diode ka kooban yahay afar dioska- diyaarin on board Bannaanka, oo kii labaadna wuxuu ahaa waxaa lagu soo bandhigay sida shir is haysta. Inkastoo 1N4007 taxanaha ah oo lagu kalsoonaan karo in qalliin, shirkii MS250 badbaadiyay miisaanka iyo raad. Iyadoo ay taasi jirto, taxane ah oo baahida 1N4007 mid sare, sida qiimaha ayaa hoos u dhacay si ka badan in inta badan uu go'aamiyo qiimaha gabagabadii oo ah naxaas.

technology Warshadaha ee MS biriijyada diode taxane sii. Hadda oo dhan 4 of buundada crystal ayaa la wada rakibay, taas oo kordhinaysa iska caabin ah oo ay sabab u tahay heerkulka xuduudaheedu midayso ah.

rectifier halaynta hoos ula sii kordhaya heerkulka daarmayaay'e. Dhibaatadaan waa xalin by taxane B250S2A qalab xisaabiyaa on hadda ah 2.3 A iyo 0.7 transmissive A at 125 ° C.

saarayaasha intooda badan ka iibsan dioska-, oo korkoodana waxaa rectifiers diyaar. Shirkadda ayaa ku hawlan wax soo saarka dhan Diotec, ka saaridda of kiristaalo in ay wada shiraan iyo xirmo.

dunida kale shirkadda keentay - IRF - haysto teknoolajiyada gaar ah loo yareeyo size ee qaybo ka mid, loo hagaajiyo kala iibsiga kulaylka, kordhinta tayada of technology Semiconductor. Iyadu waa mid ka mid ah oo kaliya in ay soo saartaa qaybaha for wareegga diinta tamarta oo dhan.

gunaanad

circuit ee rectifier buundada diode la isticmaalay dhammaan qalabka elektarooniga ah. Waa in lagu dabaqaa rectifier ruxruxo buuxa, kuwaas oo sifooyinka waa badan ka wanaagsan yahay hal muddo. Hubi kasta oo iyaga ka mid noqon madax banaan prozvoniv kartaa diode kasta.
