Electronically sarrafawa fitilar: diode da triode

Bari mu magana game da electronically sarrafawa bawuloli.

Mene ne electronically sarrafawa hasken wuta?

Electronically-sarrafawa fitilar - shi ne lantarki kayan da wani yawan wayoyin da da lantarki ne kawai a daya shugabanci. Daga cikin yawan wayoyin dogara da sunan fitilar: diode (biyu wayoyin), a triode (uku wayoyin), pentode (biyar wayoyin), da dai sauransu, suna amfani da wutar lantarki, aikin injiniya, Electronics, ikon da yawa sauran masana'antu ayan gyara da alternating lantarki halin yanzu .. kazalika shafi na yanzu mita, aiki a matsayin injimin gano illa da kuma canjawa da ikon da'irori. Ba ka san me ya sa akwai wani diode da triode? Ci gaba zuwa magance wannan rata.

diode

A diode ne electronically sarrafawa fitilar a cikin abin da akwai guda biyu da wayoyin. Diodes da transistors na daban-daban hardware bangaren shi ne yawan wayoyin, tuna da wannan. Bisa ga jiki ka'idoji, da aiwatar da su aiki ne zuwa kashi irin iri (da bi, kowane jinsin aka raba wani yawan sub-jinsunan):

1. Electric injin. Amfani ga gyãrawa. Lokacin da ya kona wa ake so zafin jiki na cathode (idan akwai wani thermoelectric watsi) an ciyar da anode dangi da cathode ƙarfin lantarki ne tabbatacce. Sai wata ƙungiya daga liberated electrons directed zuwa da anode, da kuma diode halin yanzu da aka kafa. Idan wannan bai faru, sa'an nan electrons komawa zuwa cathode.

2. Fitar. Amfani na manyan ikon amplifiers da kuma karfafawa daga manyan gajiyan. Wakiltar wani cathode da wani anode aka sanya shi a cikin wani inert gas ko gas cakuda karkashin wani matsin lamba.

3. Semiconductor. Zai yiwu aikace-aikace ne sosai bambancin. Shin na'urorin a cikin abin da gãfarta lantarki mika mulki da akwai guda biyu waje fitarwa. Kamar yadda gyara lantarki mulki ne a pn Junction, a semiconductor-karfe lamba ko giperperehoda.

triode

Ba kamar diode, triode, fãce anode da cathode, kuma yana da karin iko lantarki, wanda aka kira a layin wutar. Dake tsakanin anode da cathode don sarrafa Grid damar da fitilar electron kwarara ta canza size da kuma polarity da irin ƙarfin lantarki tsakanin layin wutar da cathode. Shi ne saboda wannan ikon da aka kira layin wutar iko.

Net, a mafi yawan lokuta, shi ne wani Helix na bakin ciki waya wadda na kewaye da cathode. Samar da shi daga nickel, molybdenum, su gami, da Tantalite, kuma tungsten. A kasan yuwuwar na Grid, da mafi aikin yana yin wani electron tafi zuwa filin. A karkashin wani mummunan dabi'u na ƙarfin lantarki, babu electron ba za su iya dakatar da tashar wutar lantarki filin, da kuma anode halin yanzu na transistor zai zama sifili. Triols sukan yi amfani da su kara da sigina lokacin samun eriya bim.

m amfani

A transistor da diode, da kimiyyar lissafi da suka yi amfani da sun kunna ingantaccen mataki a gaba da ci gaban kome da aka haɗa da wutar lantarki. Yana da wuya a kwatanta ba tare da gidajen radiyo kan ware, televisions, kwakwalwa, tarho, da kuma sauran abubuwa. Diodes da transistors amfani ba kawai a cikin manyan-sikelin samar, amma kuma ta rediyo yan koyo da kuma rediyo lantarki a cikin gida da gwaje-gwajen. Yana da wuya a kwatanta wani ci-gaba buga kewaye hukumar, wanda zai gudanar da hadaddun fasaha, da kuma a cikin abin da za a electronically sarrafawa fitilu. Diodes da transistors da mai fadi da kewayon aikace-aikace, don haka gaban da dama daga wadannan sauran na'urar daga duk wani naman alade rediyo ne kusan tabbacin. Amma su m aikace-aikace ya yi da hankali - yana da kayan, wanda aiki tare da wani irin ƙarfin lantarki, ko da shi ne kananan, amma sakamakon zai kasance a kalla m kyalewa aminci dokoki.
