Half-kalaman rectifier, ta aiki manufa da kuma kewaye

Ikon lantarki ga dalilai daban-daban bukatar wani DC ƙarfin lantarki Madogararsa. A al'ada gida cibiyar sadarwa alternating halin yanzu, ta mita ne a mafi yawan lokuta 50 Hz. Siffar canji generated ƙarfin lantarki darajar ne a sinusoid tare da wani lokaci na 0.02 seconds, tare da daya da rabi zuwa tsaka tsaki shi ne m, na biyu - korau. Don magance matsalar da canji a cikin wani m aiyuka AC rectifiers. Sun zo a cikin daban-daban kayayyaki da kuma makircinsu iya bambanta.

Domin fahimtar yadda mafi sauki rabin-kalaman rectifier, wanda dole ne da farko gane yanayin lantarki watsin. Yanzu ne directed motsi na cajin barbashi wanda na iya samun wani m polarity, conventionally suka kasu kashi electrons da ramuka, ko - gudunmawa da acceptors da ciwon watsin «n» da kuma «p» type, bi da bi. Idan abu daga n-watsin haɗawa tare da wani, p-type, a su ke dubawa da ake kira pn-maha? Ar bounding da motsi na cajin barbashi don daya shugabanci. Wannan samu a yarda da yin amfani da fasahar semiconductor, ya maye gurbin ta fi tube lantarki.

Half-kalaman rectifier m qunshi wani diode na'urar da pn maha? Ar. A alternating ƙarfin lantarki kawota zuwa shigar da kewaye, da fitarwa ƙunshi kawai rabin shi, da wanda ya dace da shugabanci sharuddan sauyawa rectifier diode. A kashi na biyu na zamani, da ciwon gaban shugabanci, kawai ba ya wuce da kuma "yanke da su."

A zane na nuna wani mai guda-lokaci rectifier cewa an yi amfani da mafi sau da yawa a cikin talakawa gida na'urorin da aka yi nufi ga m amfani. A wani m yanayi sau da yawa amfani uku-lokaci cibiyar sadarwa, sabili da haka da AC zuwa DC Converter kewaye iya wuya. Bugu da ƙari, kamar yadda mai mulkin, sun hada da sarkar na fis din da tacewa. A kewaye da shigar da za a iya juya saukar da gidan wuta ko wasu AC Madogararsa. Rectifier diodes bambanta a cikin sigogi, sarki daga cikinsu shi ne na yanzu darajar a da diode aka tsara.

Half-kalaman rectifier yana da wani gagarumin hasara a kwatanta da cikakken-kalaman. A irin ƙarfin lantarki bayan da kyautatuwar al'amuran ba a zahiri m, shi pulsates daga matsakaicin darajar da sifili da polusinusovidnoy jadawali form, kuma yana da tsakanin hatsaisai sifili. Irin m kwarara kullum cika wa ta ciki har da wani smoothing capacitor fairly manyan yawa (wani lokacin auna a dubban microfarads) lasafta ga wani irin ƙarfin lantarki ba kasa da ya auku a kewaye fitarwa, kamar yadda mai mulkin, tare da wani gefe. Wannan gwargwado kuma tabbatar da cikakken flatness graphics, amma girma na sabawa daga setpoint an rage muhimmanci, wanda ya sa ya yiwu don amfani mai rabin-kalaman rectifier for powering sauki haihuwarka ba bukata high ƙarfin lantarki kwanciyar hankali.

A mafi halaye da wuya, yi amfani da cikakken-kalaman gyara kewaye bi ta karfafawa.
