A full-kalaman rectifier, da kuma yadda yake aiki

Rectifier kira wutar lantarki converters, wanda suke semiconductor ko wasu na'urar lantarki ga tana mayar AC shigar da ikon zuwa DC fitarwa. Kalaman rectifier gina a kan wani rabin-gada ko gada kewaye, da cikakken samuwar abin da za mu yi la'akari.

Jigon da na'urar da cikakken-kalaman rectifier

Yawancin wadannan na'urorin Halicci unidirectional ripple ƙarfin lantarki. Don santsi da pulsation, yi amfani da musamman tacewa.
Don inganta rectifier sigogi dole don samar halin yanzu kwarara duka biyu rabin lokaci na shigar da irin ƙarfin lantarki. A saboda wannan dalili, iri biyu haihuwarka amfani da rabin-kalaman gyãrawa, wanda aiki a matsayin antiphase kuma a synchronism da na kowa load.

Tare da wannan hada bukatar biyu farko ƙarfin lantarki source, wadda za ta da na kowa ma'ana. Wannan makirci ne da ake kira "full-kalaman rectifier da tsakiyar aya." A talakawan darajar ƙarfin lantarki a load resistors a cikakken-kalaman kyautatuwar al'amuran wannan Manuniya zai wuce sau biyu da rabin-kalaman kewaye.

Ya kamata a lura cewa dvuhpolupeiodnoy makircinsu mallakan da midpoint, yana ta korau al'amurran. Lokacin da na yanzu wuce da daya diode a gaban baya ƙarfin lantarki ganiya a lokaci kai a kalla sau biyu, da shigar da ƙarfin lantarki, abin da ya kamata a tuna da zabi diodes ga rectifier.

A wannan batun, la'akari da wani karin cikakken cikakken-kalaman rectifier kewaye da ciwon wani karfe abun ciki da ciwon manyan aiki m ciki juriya. Wannan take kaiwa zuwa gaban manyan hasarori hade da wani gagarumin dumama da gidan wuta.

A gina irin wannan rangadi da ciwon smoothing capacitor, shi wajibi ne don la'akari da cewa ji alternating ƙarfin lantarki ne ko da yaushe a cikin aiki da dabi'u, wanda suke da muhimmanci fiye da karami da matsakaicin mawadãta. A cikin rashi na aza a kan capacitor da gãfarta ƙarfin lantarki ne ko da yaushe daidaita mawadãta. Wannan yana nufin cewa da cikakken-kalaman rectifier da ciwon guda-lokaci alternating halin yanzu na capacitor 12, a lokacin da babu kaya sami wani irin ƙarfin lantarki na 17 V. Daga wannan, za mu iya cewa a karkashin load da gãfarta ƙarfin lantarki da rage-rage, amma ba ya zama kasa da ƙarfin lantarki data kasance canji halin yanzu kuma za a ƙaddara da damar a smoothing capacitor.

Irin wannan rectifier kewaye da aka bayyana kamar haka. Domin kashe da tsangwama daga cikin gidan wuta farko Tuddan an haɗa zuwa tace, wanda aka hada da biyu capacitors da a haɗe tsakiyar aya zuwa ga ƙasa. Suna da ake bukata domin unipolar, kuma don rage rashin lafiya Yiwuwar da rated ƙarfin lantarki a su ne 200 V.

Yawanci, da canza an saita zuwa da condenser, shi wajibi ne don hana da mains ƙarfin lantarki a lokacin aiki a cikin rectifier capacitors. Fullwave rectifier gidan wuta yana da wani sakandare Tuddan tare da wata cibiyar famfo, amma a cikin wannan gada kewaye fitarwa ba lallai ba ne. Tace ga rectifier da capacitor ne biyu jerin resistor. Duk da haka, a low matakin na ripple ne m don ƙara wani fitarwa capacitor da resistor.

Tun lantarki inji aiki bisa ga ka'ida da reversibility, irin ƙarfin lantarki rectifiers tare da inverter iri biyu lantarki inji. Kira inverter na'urar sabobin tuba DC ƙarfin lantarki zuwa AC.
