Iyo yakagadziriswa semiconductor chikamu-iyo diode- inogadzirisa zvakasiyana-siyana mabasa anobatsira anoenderana nechinangwa chayo chikuru chekutarisira mutungamiri wekuyerera kwemazuva ano magetsi. Diodes inobvumira ikozvino kuti ibudirire kuburikidza navo mune imwe nzira chete.
Zviratidzo zvakakwana zvakakwana zvinoita sedare dzakasununguka nemhepo isina kunaka uye dzinotarisa semakwikwi maduku zvimwe. Asi nokuti diodes inobvuma kune zvimwe zvisingakwanisi, huripo-ku-voltage hukama haisi nheline.
Sezvo zvakadaro, iwe unoda kutarisa diod's datasheet kuti uone girafu yemakumbo epio ipi zvayo yakatarisa inotenderera yakafanana neyo mberi kwayo ikozvino, kuitira kuti iwe usarudze diode yakarurama yeimwe purojekiti yako.
Applications of Diodes
Pasinei nokungova maitiro maviri maviri-pin semiconductor, madiodhi anokosha mumazuva ano emagetsi. Zvimwe zvezvinyorwa zvekushandiswa kwe diod dzinosanganisira:
- Kuvandudza magetsi, akadai sokuchinja AC kuDt voltages
- Kuparadzanisa zviratidzo kubva pane zvekushandisa
- Kudzora hukuru hwechiratidzo
- Kusanganisa zviratidzo
Power Conversion
Chimwe chinhu chakakosha chekushandiswa kwe diodes ndiko kushandura AC simba ku DC power. Rimwe diode kana diode ina inogona kushandiswa kushandura 110V simba remhuri ku DC nekuumba hafu (single diode) kana full-wimbi (mana diode) kugadzirisa . Chidimbu ichi chinoita izvi nokubvumira hafu yeA AC waveform kufamba nayo. Apo iyi inonzi pulse inoshandiswa kutengesa a capacitor, iyo inobuda gasi inoita seyo inogara yakasimba DC inokonzerwa nechingoro chiduku. Kushandisa aine-wave-wave remtifier inoita kuti urongwa uhwu hubudirire kuburikidza nekugadzirisa kubuda kweA AC kuitira kuti zvikamu zviviri zvakanaka uye zvisina kunaka zvemugove wechipfuva zvinowanzoonekwa semafungiro akanaka chete, zvichibudirira zvakapetwa kuwandisa kwemashoko ekufambisa kune vane capacitor, inobatsira kuchengeta iyo inopomerwa uye kununura kuwedzera kwemhepo.
Diodes uye capacitors zvinogonawo kushandiswa kugadzira huwandu hwemarudzi ehuwandu hwemhepo hutori kutora duku AC voltage uye kuowedzera kuti huve yakakwirira kwazvo kubuda kwemhepo. Zvose zviri zviviri zve AC uye DC zvinobvira zvichigadzirisa kushandiswa kwekodzero yekugadzirisa ma capacitors uye diodhi.
Kuodhirwa Kwemashoko Ezviratidzo
Kunyanya kushandiswa kwemadiodhini ndiko kubvisa chikamu chakaipa chechiratidzo cheA AC. Nemhaka yokuti chikamu chakaipa cheA AC waveform inowanzofanana nehafu yakanaka, ruzivo ruduku zvikuru rwakarasikirwa nenzira ino yekubvisa iyo, zvichiita kuti zviratidzo zvakanyatsoshanda zvigadziriswe.
Chiratidzo chekugadzirisa zvinowanzoshandiswa mumirasiyo sechikamu chekutsvaga kwenzira yekubatsira kubvisa chiratidzo cheredhiyo kubva kumhepo inotakura.
Over-Voltage Protection
Diodhe inoshandawo zvakanaka sezvidziviriro zvekuchengetedza kwezvinhu zvinotengesa magetsi. Kana inoshandiswa semagetsi ekudzivirirwa kwemagetsi, madiodhi haasati achigadzirisa pasi pemaitiro anowanzoshanda asi zvino pfupi pfupi chero ipi zvayo yepamusoro-gorosi inokwira pasi iyo inenge isingagoni kukuvadza imwe yakatenderedzwa. Zvimwe zvinonzi diodes zvinonzi pasi pemazuva ano zvinokonzerwa nemhepo zvakasununguka uye zvinogona kushandisa zvakanyanya simba simba spikes kwenguva shoma, izvo zvinowanzoonekwa sevheti yevasi kana kushamiswa kwegesi, iyo inowanzovhiringidza zvikamu uye kuderedza hupenyu hwehuwandu hwemagetsi.
Saizvozvowo, diode inogona kutonga magetsi kuburikidza sekushambadzira kana kugadzirisa-chinangwa chinonyanya kukosha iyo inogona kupfuura nayo pane imwe pfungwa.
Current Steering
Iko kushandiswa kwemashoko ediodhi ndiko kutora nguva uye kuve nechokwadi kuti inongoyerera chete nenzira yakakodzera. Imwe nzvimbo iyo ikozvino kuitisa kwemadiodhi kunoshandiswa kuita zvakanaka kunoshanduka kubva kune simba rinobva kune simba rekuisa simba rinobuda kubva kubheteri. Apo chigadzirwa chabudiswa mukati uye chinotengesa-somuenzaniso, foni kana kuti zvisingaverengeki simba rekupa-chigadziro chinofanira kunge chiri kutora simba kubva kunze kwekugonesa kwemasimba uye kwete bheteri, uye apo iyo chipuriti ichibudiswa mubheti inofanira kunge ichiita simba uye recharging. Pangosvika simba rinobviswa, bhatiri inofanira kusimbisa chigadzirwa kuitira kuti kusakanganiswa kuonekwe nemushandisi.
Muenzaniso wakanaka wekutungamira ikozvino uri kuburikidza nekudzivirirwa kwemazuva ano. Funga, somuenzaniso, motokari yako. Kana bheneri yako yafa uye shamwari inofambidzana inopa rubatsiro nejumper cables, kana uchisanganisa urongwa hwemasimbi matsvuku uye madema iwe haungatsvaki motokari yemotokari yako nokuti diodes iri pedo nebheteri inotadza-kutungamirira ikozvino.
Logic Gates
Makombiyuta anoshanda mumabhinari-gungwa risingaperi risina zero uye rimwe. Miti yemabhinari inogadzirisa inyanzvi inobva pane logic masvingo inobvumirwa ne diode inodzora kana kuchinja kuri ku ("1") kana kuti kure ("0"). Kunyange zvazvo mazana emamiriyoni emadiodhi anoonekwa mumagadziro emazuva ano, anoshanda zvakangofanana nea diod iwe unotenga pane magetsi e-magetsi-zvishoma zvishoma.
Diodes uye Chiedza
Chiedza che LED chinongova chiedza chechiedza chacho chinovhenekera chinobva pachiedza chine chiedza. Muchipo chemafuta akanaka, LED dzinopenya.
A photodiode, zvakasiyana, anogamuchira chiedza kuburikidza nevatori (semuchina wezuva masikati) uye anotendeuka kuti chiedza chive chiduku chezvino.
