Munyika yakaoma yemagetsi, madhiodhi anotonga zvakanyanya sezvinhu zvakakosha zvinotonga mafambiro emagetsi. Pakati peakasiyana siyana edhiodhi, maZener diode uye akajairika diode anomira pachena, imwe neimwe iine akasiyana maitiro uye mashandisiro. Nepo vese vari vaviri vachiita basa rakakosha mumaseketi emagetsi, kunzwisisa mutsauko wavo kwakakosha pakusarudza diode yakakodzera yerimwe basa.
Kuongorora mune Regular Diodes
Regular diodes, anozivikanwawo sePN junction diodes, ari semiconductor midziyo inobvumira ikozvino kuyerera munzira imwe (mberi) ichivharira kune yakatarisana (reverse direction). Ichi chivakwa chekugadzirisa chinovaita zvinhu zvakakosha mukushandura alternating current (AC) kuti itungamire ikozvino (DC).
Kuongorora Zener Diodes
Zener diode, rudzi rwemhando ye diode, inogovera chimiro chakakosha uye kugadzirisa zvimiro zvenguva dzose diode asi inoratidza humwe hunoshamisa hunhu: kudzorwa kuparara. Kana ichiiswa kune reverse bias voltage inodarika voltage yavo yakatarwa yekuparara, Zener diodes inoputsika, ichigonesa ikozvino kuyerera ichidzokera kumashure. Ichi chinodzorwa chekuputsika chiitiko chinoumba hwaro hwekuita kwavo kwakasiyana.
Kufumura Misiyano Yakakosha
Musiyano unotsanangura pakati peZener diodes uye diode akajairwa uri mukuparara kwavo maitiro:
Kuputsa Mechanism: Diode dzenguva dzose dzinoratidza kuparara kweavalanche, isingadzoreki uye inogona kuparadza maitiro. Zener diodes, kune rumwe rutivi, inopinda Zener kuputsika, inodzorwa uye inofanotaura kuparara chiitiko.
Breakdown Voltage: Madhiodhi akajairwa ane huwandu hwakasiyana hwekuparara kwemagetsi, kazhinji achisiyana nekugadzira kushivirira. Zener diodes, nekupesana, inozvirumbidza yakanyatsotsanangurwa uye yakavimbiswa kuparara kwemagetsi, zvichiita kuti ive yakakodzera kune voltage regulation application.
Zvishandiso: Madhiodhi akajairwa anonyanya kushanda seanogadzirisa, achishandura AC kuita DC. Zener diodes inokunda mukutonga kwevoltage, kudzivirira kweovervoltage, voltage clamping, uye waveform shaping.
Kusarudza Diode Yakarurama
Sarudzo pakati peZener diode uye yenguva dzose diode zvinoenderana neiyo chaiyo application:
Kugadzirisa: Madhiodhi akajairwa ndiyo sarudzo yakasarudzika yekushandura AC kuita DC.
Kune voltage regulation: Zener diodes ndiyo yakanakira sarudzo yekuchengetedza yakagadzikana voltage pamutoro.
Nekudzivirira kwe overvoltage: Zener diodes inochengetedza zvinhu zvinonzwa nekuvharira yakawandisa voltage kusvika pasi panguva yekuvhiya kana spikes.
Yemagetsi clamping: Zener diodes inogona kudzikisira iyo yakanyanya kana diki voltage mazinga mudunhu, kudzivirira kukanganiswa kwechiratidzo.
Kune waveform kuumbwa: Zener diodes inogona kuumba waveforms nekucheka kana kugadzirisa masaini eAC.
Mhedziso
Zener diodes uye diodes anogara achigovana hwaro hwakafanana, anosiyana mukuparara kwavo maitiro uye mashandisiro. Zener diodes, ine yakanyatsotsanangurwa kuparara kwemagetsi uye kugona kudzora magetsi, inopenya mumashandisirwo anoda kugadzikana uye dziviriro. Madhiodhi enguva dzose, nehunyanzvi hwawo hwekugadzirisa, anokunda mukushandura AC kuita DC. Kunzwisisa misiyano iyi kunopa simba vanofarira zvemagetsi kuita sarudzo dzine ruzivo pakusarudza diode yakakodzera yemapurojekiti avo.
