Mukombiyuta kudzora rambi: diode uye triode

Ngatimbotaura pamusoro mukombiyuta kudzora mavharuvhu.

Chii mukombiyuta kudzora mwenje?

Mukombiyuta raitungamirirwa rambi - iri midziyo yemagetsi ine vamwe nhamba electrodes kuti magetsi chete rimwe divi. Kubva uwandu electrodes kunoenderana zita rambi: diode (electrodes maviri), mumwe triode (electrodes matatu), pentode (electrodes mashanu), etc. Ivo zvinoshandiswa magetsi engineering, zvemagetsi, simba uye dzimwe maindasitiri mazhinji vanowanzopedzisira azvigadzirise rakatumbuka Magetsi .. uyewo sei kuitika kakawanda, ave ari detector uye chinja simba madenderedzwa. Hamuzivi sei pane diode uye triode? Munobuda kuzogadzirisa gwanza ichi.

diode

A diode ane mukombiyuta kudzora rambi umo mune electrodes maviri. Diodes uye transistors dzakasiyana zvinoriumba Hardware inhamba electrodes, yeuka izvi. Pahwaro mumuviri dzemitemo, ari Implementation pamusoro functionality ravo rakakamurwa mhando yakadaro (azvaitwa, mumwe mhando rakakamurwa dzinoverengeka Sub-rudzi):

1. Electric Vacuum. Kushandiswa rectification. Kana neshungu kuti aida tembiricha iri cathode (kana paine thermoelectric achine) zvokudya kuti anode hama kuti cathode voltage akanaka. Zvino chikamu vasunungurwa maerekitironi rinotungamirirwa kurutivi anode, uye diode pari aumbwa. Kana izvi zvikasaitika, ipapo maerekitironi kudzokera cathode.

2. Zvinoyerera. Kushandiswa hombe simba amplifiers uye Kudzikamiswa makuru kunetseka. Vanomiririra cathode uye anode inoiswa imwe inert gasi kana gasi muvhenganiswa pasi mumwe kumanikidzwa.

3. Semiconductor. Possible mafomu vari siyana chaizvo. Ndangariro umo kunogadzirisika yemagetsi kuchinja uye pane mbiri goho kwokunze. Sezvo kugadzirisa zvemagetsi Kuchinja ari PN Junction, mumwe semiconductor-metal kuonana kana giperperehoda.

triode

Kusiyana diode, triode, kunze anode uye cathode, uye ane zvakawanda kudzora electrode, unonzi grid. Zvayaiva pakati anode uye cathode kudzora afoot anobvumira rambi Erekitironi nokuyerera nokuchinja kukura uye polarity pamusoro voltage pakati afoot uye cathode. Imhaka kugona ichi inonzi afoot kuzvidzora.

Net, kazhinji, ndiko akamonyoroka kuti mutete waya iyo runopoteredza cathode. Kubereka kubva nickel, molybdenum, avo alloys, uye tantalum, uye tungsten. Rezasi zvinogona kubva afoot, zvikuru basa anofanira kuita Erekitironi ndiende kumunda. Under vamwe tsika voltage kunaka, hapana Erekitironi havazokwanisi kumisa afoot munda, uye anode kuitika pamusoro transistor achava razero. Triols anowanzoshandiswa kuti rinowedzera chiratidzo kana kugamuchira kanyanga matanda.

zvinobatsira

The transistor uye diode, ivo wefizikisi zvavo kushandisa zvakaita Qualitative danho kukura zvose zvine chokuita nemagetsi. Zvakaoma kufungidzira pasina maredhiyo, materevhizheni, makombiyuta, nhare, uye zvimwe zvinhu zvizhinji. Diodes uye transistors inoshandiswa kwete chete munzvimbo huru dzinotambudza kugadzirwa, asiwo redhiyo amateurs uye redhiyo zvemagetsi mumusha mavo kuedza. Zvakaoma kufungidzira imwe yepamusoro akadhindwa redunhu puranga, izvo zvichaita kuti utarisire zvakaoma ano, uye iyo ichava imomo mukombiyuta kudzora mwenje. Diodes uye transistors vane akasiyana chaizvo siyana mafomu, saka kuvapo anoverengeka tsva mudziyo izvi chero hamu redhiyo iri rinenge kodzero. Asi kushanda kwavo vanofanira kungwarira - zviri midziyo, izvo anoshanda ane voltage, kunyange kana chiri chiduku, asi zvichaitika kanenge hachifadzi nokusateerera yakachengeteka mitemo.
