The zida ndi opareshoni mfundo za rectifier dera diode mlatho

Alternating magetsi masiku ano anatembenukira kwa DC pulsed pogwiritsa ntchito madera wapadera zamakono - diode milatho. Diode mlatho rectifier dera lagawidwa Mabaibulo awiri: mmodzi gawo ndi atatu gawo.

Kwenikweni rectifier amafotokozera ndi diode. Amapanga, ndi mbale wa Chip michenga yopangira zida zamagetsi ndi mabacteria awiri osiyana madutsidwe. Mbali A ndime unilateral ya magetsi, malingana akulowera.

Kapangidwe ndi ntchito ya rectifier diode zochokera mbali michenga yopangira zida zamagetsi pn kusintha pakati mabacteria ndi. kukana umadalira pa polarity wa voteji kunja. Ngati munthu, ndi yayikulu, mu zina - pang'ono.

The osakwatiwa-gawo diode mlatho

Pamene athandizira - AC sine yoweyula voteji mu lililonse mkombero theka la pano umadutsa awiri diodes ndi zina kutsekedwa. Chifukwa, dera linanena bungwe kupangidwa kwa diode mlatho rectifier ripple voteji ndi pafupipafupi kawiri lalikulu kuposa pa polowera lapansi.

Mlatho dera atatu gawo

dera amagwiritsa ntchito diode theka mlatho rectifiers. The linanena bungwe voteji analandira ndi pulsations ang'onoang'ono.

Kodi kusalaza ripple pa kuwongola mphamvu?

Khalidwe la voteji kudzatha amachepetsa ndi kuwonjezeka mu pulsation ake. Kuchepetsa izo, ntchito zinthu, wambirimbiri mphamvu pamene amaperekedwa ku rectifier chitakonzedwa pa kuchotsa Kutengera ake.

Taperekachi, ndi diode mlatho rectifier ndi capacitor olumikizidwa ku kufanana ndi katundu lomaliza. yosungirako mphamvu amusankha malingana ndi katundu panopa. Pamene ntchito zimachitika pa capacitor ndi kulipiritsa. Pakati nyemba (akakhala), kwapatsidwa ndi voteji katundu.

Chifukwa cha kuwongola fyuluta linanena bungwe voteji amakhala zazikulu ndi njira mtengo wa kudzatha mtengo matalikidwe.

An voteji abwino pa linanena bungwe la sefa sungagulire chifukwa cha kumaliseche kwa capacitor pakati nyemba. Childs, pulsations izi zodyedwa. Iwo akhoza anatsika ndi kuwonjezeka capacitance wa capacitor lapansi.

Ngati kuwongola inductor ntchito, kuti chikugwirizana pa mndandanda ndi katundu. Ophatikizana fyuluta dera zikuphatikizapo inductors ndi capacitors.

Yomanga diode mlatho

Losavuta chipangizo mlatho anachita kudzera diodes osiyana adhesions. makampani umabala nyumba monolithic kuti ali ang'onoang'ono kukula ndi mtengo. Komanso, iwo chikufanana diodes ndi makhalidwe ofanana, kuti zimawathandiza kugwira ntchito ndi kutentha yomweyo. Zimenezi kudalirika kwa dera diode mlatho rectifier.

Ubwino wa diode mlatho wa zinthu payekha amatha kukonza, pamene wina wa iwo amalephera. Msonkhanowu alinso ndi m'malo kwathunthu. Akulakwitsa izo n'zochepa, chifukwa zinthu ndi bwino chikufanana.

mphamvu rectifiers

Zipangizo kulakalaka panopa chachikulu, ambiri ali zoyendetsedwa ndi 220 V. zipangizo Direct sali olumikizidwa, kuyambira voteji wofunikila madera a pakompyuta ndi ang'onoang'ono, apano - zonse. Ndiye ntchito AC adaputala.

Voteji adatchithisira ndi thiransifoma ndi zomwe amalenga kudzipatula galvanic pakati unyolo pulayimale ndi sekondale chakudya. Izi amachepetsa chiopsezo mantha magetsi ndipo atetezedwe zida pamene yochepa-dera ku dera la.

adaputala azamagetsi Modern ntchito nthawi zambiri pa wosalira transformerless dera popanda kudzipatula galvanic, mmene mphamvu owonjezera ndi chosakanikirana ndi capacitor lapansi.

Pothamangitsa diode mlatho 12 volts: malangizo ndi msonkhano

The magetsi imakhala zigawo ziwiri, kumene woyamba - sitepe-pansi thiransifoma, ndipo chachiwiri - ndi diode mlatho otembenuka mtundu wina wa voteji ndi mzake.

Anasankha abwino thiransifoma. Chachikulu kumulowetsa ali ndi Tester a. kukana ake ayenera kukhala wamkulu. Ndi kupitiriza multimeter anakhumba malekezero ali mode kukana kayesedwe. Ndiye pali mabanja ena ndi kulemba anapanga.

Umaperekedwa kwa choyambirira kumulowetsa 220 V. Ndiye Tester ndi ikumasuliridwa ndi alternating voteji mode muyeso ndipo amaona voteji pa windings ena. Sankhani chimodzi kapena chokulungira 10 V. Nkofunika kuti voteji anali 12 V, kuyambira sefa capacitive pambuyo izo chinawonjezeka ndi 18%.

thiransifoma The kusintha kwa mphamvu akufuna, ndiye katundu atengedwa ndi 25%.

4 zopotoka diode mu diode mlatho ndipo itha propaivayutsya. Ndiye dera la chikugwirizana, pa capacitor linanena bungwe chikugwirizana 25 V ndi 2200 MF (electrolyte) ndi kutsimikizika mu ntchito.

Transformerless dera la volts diode mlatho rectifier 24

Zochita zofufuzafufuza chimagwiritsidwa ntchito otsika mphamvu mphamvu okwanira popanda tiransifoma.

Mphamvu okwanira 220 umaperekedwa mwa ballast capacitor C1. The rectifier tichipeza diodes VD1, VD2 ndi Zener diodes VD3, VD4. Kuthetsa kukakhala panopa kudzera mlatho kulumikiza mphamvu capacitor mu mndandanda ndi panopa Kuchepetsa resistor wayikidwa kulimbikira 50-100 ohms. Kuti zimatulutsa capacitor pamene wosweka dera, olumikizidwa ku kufanana thereto 150-300 kohm resistor.

Dera linanena bungwe wayikidwa kuwongola capacitor ndi capacitance cha 2000 PF.

Chosowa galvanic kulankhulana amalenga ngozi mantha magetsi.

ntchito

Mapulogalamu a diode mlatho n'chachikulu kwambiri zosiyanasiyana:

• kuyatsa (kutsogozedwa ndi nyali fulorosenti);
• zipangizo magetsi metering;
• mayunitsi magetsi zida zamagetsi;
• mafakitale mphamvu okwanira, ulamuliro ndi chargers.

Kodi kusankha diode atapanga diode mlatho?

Waukulu kusankha muyezo ndi voteji ndipo panopa pa zimene diode si ukagwira. Mu mwachindunji kulolerana adalira imagwera voteji za 0,6 V, ngati iwo ali ndi kukana mkati. N'zosiyana voteji kuti diode kukamaomba popanda kulowa ikukhudzana ndi magetsi kusokonezeka mode, ali ndi malire ena. Ngati lakonzedwa 220 V, pamafunika katundu wa osachepera 25%. Koma ndi bwino kutenga izo opondapo kuti adziteteze mwangozi mphamvu mzere kukakhala.

Masiku ano naonso anatengedwa ku malo a. Ngati ndi kotheka, limatipatsa Redieta yozizira.

Pakuti mwanzeru pa tebulo Buku ali diodes ndi diode milatho.

Opanga diode milatho

Mwa zinthu kuunikira kumbali rectifiers mndandanda 1N4007 ndi MS250 chopangidwa ndi Diotec. Iwo anapangidwa kuti voltages mpaka 1000 V. Mbali yoyamba, ndi diode mlatho dera tichipeza diodes anayi anakonza pa bolodi dera, ndipo wachiwiri ndi kuperekedwa monga msonkhano yaying'ono. Ngakhale mndandanda 1N4007 odalirika opareshoni, khamu MS250 amapulumutsa kulemera ndi zotsalira. Ngakhale izi, mndandanda wa kufunika 1N4007 amakhalabe mkulu, monga mtengo wakhala waponya kwambiri kuti makamaka anatsimikiza ndi mtengo wa mfundo za mkuwa.

Kupanga luso la MS mndandanda diode milatho akupitiriza. Tsopano onse 4 mlatho galasi amene anaika pamodzi, amene kumawonjezera kutentha kwake kukana chifukwa magawo pachilichonse.

Kudalirika rectifier amachepetsa ndi kuwonjezeka yozungulira kutentha. vuto Izi anathana ndi mndandanda chipangizo B250S2A masamu pa panopa 2.3 A ndi 0,7 A transmissive pa 125 ° C.

opanga kwambiri kugula diodes, inatuluka rectifiers wokonzeka. kampaniyo chinkhoswe mu Diotec kupanga lonse, kuyambira kupanga timibulu kusonkhanitsa phukusi.

Wina dziko kutsogolera kampani - IRF - nazo umisiri wapadera kuchepetsa kukula kwa ziwalo, kusintha kutentha kusintha, kuwonjezera dzuwa la sayansi michenga yopangira zida zamagetsi. Iye ndi yekhayo amene umabala zigawo za lonse mkombero mphamvu kutembenuka.

Pomaliza

The dera la rectifier diode mlatho ntchito zida zonse zamagetsi. Kodi ntchito zonse yoweyula rectifier, amene makhalidwe ati kuposa osakwatiwa-nthawi. Chongani aliyense wa iwo akhoza kukhala paokha prozvoniv lililonse diode.
