The midziyo uye uchishandisa nhungamiro imwe diode zambuko rectifier redunhu

Rakatumbuka zvemagetsi ano iri vatendeukira DC pulsed kuburikidza nokushandisa inokosha zvigadzirwa nematunhu - diode mabhiriji. Diode zambuko rectifier redunhu rakakamurwa mushanduro maviri: mumwe-danho uye zvitatu-danho.

In huru rectifier chinhu ari diode. Zvayakaita, ndiko bwendefa semiconductor Chip maviri akasiyana conductivity zvikamu. A chinhu ari yaitsigira divi ndima magetsi, zvichienderana mirayiridzo kuyerera.

Marongerwo uye kushanda rectifier diode kwakavakirwa zvinoitwa semiconductor PN yokuchinjira pakati zvikamu. kurwisa kwayo kunoenderana polarity ari kwokunze voltage. Mune imwe nyaya, zviri guru, mune dzimwe - zvishoma.

The chete-danho diode zambuko

Kana mazano - AC Sine Wave voltage neimwe hafu kutenderera magetsi ichipfuura peya diodes uye mumwe yakavharwa. Somugumisiro, mashoko goho redunhu aumba munhu diode zambuko rectifier ripple voltage ane kakawanda kaviri kupfuura panguva Inlet.

The-danho matatu zambuko redunhu

Dunhu iri anoshandisa diode hafu-zambuko rectifiers. The goho voltage inotengwa pamwe pulsations zviduku.

Sei iti chechetere ripple pa kuswatura simba?

The chatingatevedzera kunogadzirisika voltage shoma kuwedzera zvayo pulsation. Kuderedza izvozvo, kushandisa zvinhu, kuunganidza simba kana kusvitsa kubva rectifier yabviswa pamusoro kugumiswa yayo pakunamata.

Munyaya diagram, mumwe diode zambuko rectifier aine capacitor kwakabatana munguva kufanana rokupedzisira mutoro. Its okuchengetera vanokwanisa anosarudzwa zvichienderana mutoro ano. Kana kushandisa kupomba ari capacitor iri kuchaja. Between pulses (kana havasi), izvozvo anopiwa voltage mutoro.

Somugumisiro yacho rimire Sefa goho voltage kunova yakakura uye anosvika kukosha kunogadzirisika amplitude ukoshi.

An akakodzera voltage panguva goho riri Sefa hazvigoni kuwanwa nokuda zvinoyerera ari capacitor pakati pulses. Kazhinji, pulsations ava bvumidzwa. Vanogona yakaderera nezvikamu kuwedzera capacitance yacho capacitor.

Kana rimire inductor rinoshandiswa hwakabatana mu ngaatevedzane mutoro. The zvikabatanidzwa Sefa redunhu zvinosanganisira inductors uye capacitors.

Kuvaka diode zambuko

The nyore mudziyo bhiriji zvinoitwa Via yoga diodes adhesions. The indasitiri unobereka monolithic hurongwa kuti iduku pakukura uye isingadhuri. Mukuwedzera, vari vachiwirirana diodes zvakafanana unhu, kuti dzinovabvumira vashande pamwe chete kupisa. Izvi anowedzera rakavimbika diode zambuko rectifier redunhu.

The mukana diode zambuko wacho zvinhu ndiyo kugadzira, kana mumwe wavo rotsva. Gungano anewo kutsiviwa zvachose. Zvikanganiso mariri zvisingawanzoitiki, nokuti zvinhu zviri zvakanaka vachiwirirana.

Power rectifiers

Namano kuti upise hombe kuitika, zvakadai vari dzinofambiswa ne 220 V. Direct mano hazvina kubatana, sezvo voltage zvinodiwa yemagetsi matunhu riri duku, munhu kuitika - kugara. Zvadaro shandisa AC adapteri.

Voltage kutura nokuda transformer, izvo zvinoitawo kuti galvanic voga pakati nesekondari chikafu ngetani. Izvi zvinoderedza mukana yemagetsi kuvhunduka uye kudzivirirwa midziyo kana pfupi-mudunhu remudunhu.

Modern adapters anoshanda kakawanda pazuva kwainoita transformerless redunhu pasina galvanic nevamwe, sezvamakaropafadzwa zvakawandisa simba wefodya ne capacitor.

Paakadzinga diode zambuko 12 volts: mirayiridzo ungano

The simba nerubatsiro ine modules maviri, uko wokutanga - danho-pasi transformer, uye wechipiri - a diode zambuko kuti vatendeuki imwe mhando voltage kune mumwe.

Vakasarudzwa dzakakodzera transformer. The chikuru ichitenderera riri ane tester. kurwisa kwayo kunofanira kuva mukuru. By chamazuva multimeter kutsvakwa kumigumo vari kurwisa chipimo muoti. Kunewo zvimwe vakaroorana uye akaita nyora.

Chiri akapa kuna chikuru ichitenderera 220 V. Ipapo tester iri rakashandurwa kuva rakatumbuka voltage chipimo muoti uye anoyera voltage panorumwe windings. Sarudza chimwe kana vanodzungunyika 10 V. Zvakakosha kuti voltage yaiva 12 V, sezvo capacitive Sefa pashure zvikava ne 18%.

The transformer iri kugadziridzwa kuti aida simba, ipapo Nehunde anotorwa 25%.

4 yakakoswa diode ari diode zambuko uye inoguma propaivayutsya. Ipapo redunhu zvakabatana, pamusoro goho capacitor zvakabatana 25 V uye 2200 MF (electrolyte) uye zvinosimbiswa ichishanda.

Transformerless redunhu of diode zambuko rectifier 24 volts

In mudzidzi tsika zvikuru kushandiswa pasi-simba simba wedzerai pasina transformers.

Power zvitengeswa 220 iri kusvitsa kuburikidza kutsigisa igwa capacitor C1. The rectifier ine diodes VD1, VD2 uye Zener diodes VD3, VD4. Kubvisa ano RINOFAMBIRA kuburikidza zambuko unobva simba capacitor mune ngaatevedzane kuitika vakaomerwa resistor wakaiswa nemishonga kuti 50-100 ohms. Kuti akwanise capacitor kana kuputswa dunhu, zvakabatana muna zvakafanana kwachiri 150-300 kohm resistor.

The goho Dunhu iri rimire capacitor ane capacitance kwa2000 PF.

Kushaya galvanic kutaurirana anosika ngozi yemagetsi kuvhunduka.

kunyoresa

Mafomu ose diode zambuko zvikuru rakafara uye zvakasiyana-siyana:

• chiedza (akatungamirira uye fluorescent mwenje);
• magetsi metering mano;
• simba nerubatsiro zviumbu zvigadzirwa michina;
• maindasitiri simba PAKAPERA, kuzvidzora uye ndiro.

How kusarudza diode paakagadzira diode zambuko?

Huru vakasarudzwa nzira ndivo voltage uye pari panguva iyo diode haisi overheated. Zvakananga usanganidzo payo Falls voltage vanenge 0,6 V, sezvo ane zvemukati nemishonga. The neizvi voltage kuti diode unopikiana pasina kupinda chafariz uye magetsi Kuparara muoti, ane imwe muganhu. Kana rakagadzirirwa 220 V, zvinotora hunde kwete asingasviki 25%. Asi zviri nani kuti uitore yakakura zvakakwana kudzivirira netsaona simba-mutsetse RINOFAMBIRA.

Current chiri akatorwa kubva chengetedza. Kana zvakakodzera, rinotipa kutonhora redhiyeta.

Nokuti zvakanaka kusarudza bhuku tafura muri diodes uye diode mabhiriji.

Manufacturers diode mabhiriji

Pazvinhu zvine maatomu akafanana okuvimba kumira rectifiers dzakatevedzana 1N4007 uye MS250 kugadzirwa ne Diotec. Ivo zvakagadzirirwa voltages anosvika 1000 V. Muchiitiko chokutanga, kuti diode zambuko redunhu ine diodes mana akaronga pamusoro redunhu bhodhi, uye yechipiri ngachipiwe sezvo ungano tsindirana. Kunyange zvazvo akatevedzana 1N4007 yakavimbika ichishanda, gungano MS250 anoponesa uremu uye tsoka. Pasinei neizvi, dzakatevedzana 1N4007 kudiwa anoramba yakakwirira, sezvo mutengo aregedza zvokuti dzinowanzotsigi- pakutsvaga mari mhedziso zvemhangura.

Manufacturing mabikirwo MS akatevedzana diode mabhiriji mberi. Zvino zvose 4 sekristaro zambuko vari ndakagadza pamwechete anowedzera ayo tembiricha kuramba nokuda zvakafanana parameters.

Kuvimbika rectifier shoma kuwedzera ambient tembiricha. dambudziko iri kugadziriswa zano B250S2A dzakatevedzana dzaona pamusoro kwazvino 2.3 A uye 0,7 A transmissive pa 125 ° C.

Vagadziri Most kutenga diodes, pakwakanga vakagadzirira rectifiers. The kambani iri mubasa Diotec yose kugadzira, kubva zvaAtemisi crystals vaungane uye pasuru.

Imwe nyika vaitungamirira kambani - IRF - ane rakasiyana ruzivo kuderedza kukura zvikamu, kuvandudza kupisa kutapurirana, kuwedzera kushanda zvakanaka kuti semiconductor michina. Iye ndiye chete inobereka zvinoumba yose simba kutendeuka yatinofema.
