Schottky diode mune magetsi nematunhu

Pashure nokugadzirwa rokutanga semiconductor mudziyo , vaongorori vakawanda havawanzoiti ehupfumi kuti PN kukuru Junction. Sezvaungave wafungidzira, ichi chinhu chakaipa diode, izvo zvinogona kuonekwa chero zvemagetsi redunhu. Panguva yacho kuvamba, yave iri chinhu anenge revolutionized vakashandura zvose pfungwa nezveremangwana Electronics. Uyewo kuteerera kwete kuramba uye mabikirwo kwayo kugadzirwa. Akazviratidza Zener diode uye Gunn. Akatoita mumwe Schottky diode, ane ehupfumi dzinonakidza. kushandiswa kwaro mune zvemagetsi haana shamisa se "hama" dzake yakakurumbira. The dzinokosha ehupfumi kuti maatomu akafanana iyi zvamboshandiswa kushandiswa kushandiswa matunhu haana zvikuru kushandiswa. The kunakidza kuti manjemanje Schottky diode akatanga kushandiswa sezvo panozogadzirika chinhu pulsed magetsi. It Anoshanda zvinenge zvose yemagetsi mhuri priboroh: materevhizheni, VCRs, pachake makombiyuta, Laptops, etc.

Dzinenge ehupfumi ari mudziyo vanoonekwa vari pasi voltage donhwe mhiri S.-N Junction. Zviri asingasviki 0,4 volts. Kureva, parameter iyi sezvo pedyo dzakanakira chaikosha kuti rinoshandiswa Masvomhu. Zvisinei, pane imwe voltage kupfuura 50 volts, zvivako izvi zviri vakarasika. Kunyange zvakadaro, mashoko Schottky diode rave richishandiswa nevakawanda mumatunhu pamwe woshanda amplifiers. Food nematunhu kwakadaro hakuiti pfuura 15 volts DC, vachibvumira kutora zvizere zvivako zviri mudziyo. Aikwanisa kumira inofambiswa loop sechipiriso vakaomerwa Kufananidzira kana chinhanho mubasa regulators.

Kunze ichi chinokosha, sezvo voltage donhwe panguva PN Junction, ari Schottky diode ane pasi capacitance. Izvi zvinobvumira kuti kushanda padunhu-maitikiro matunhu. Zvinenge "yakanaka" zvechadenga chinhu regai vasataura mukuru-Frequency chiratidzo. Ndicho chikonzero akatanga kuisa mukati nokuchinja simba rinopiwa, kukurukura mazano uye controllers.

Asi kuwedzera kune hwakanaka zvinofanira kucherechedzwa nekuipira. Schottky diodes vanoziva chaizvo kuti kunyange kwenguva pfupi zvakawandisa neizvi voltage pamusoro zvinobvumidzwa tsika. Izvi zvinotungamirira kuti goho chinhu wegadziriro. Kusiyana zvavo nesilicon "hama", haana achapora. Thermal Kuparara anotungamirira kana kuti pasi leakage dzenzvimbo, kana kuti "kuchinja" kuti mudziyo kupinda kondakita.

Yokutanga mhosva kuchatungamirira kusagadzikana nokushanda yose wemagetsi. Hazvisi zvakaoma kuwana uye kugadzirisa. Panyaya chafariz Kuparara, ipapo, somuenzaniso, ari nokuchinja simba wedzerai kuchaita kuti kuchengetedzwa nokushanda pfupi-redunhu. Mushure kutsiva vainyeperwa chinhu simba nerubatsiro achaita basa rakanaka.

Modern indasitiri unobereka zvakakwana simba Schottky diodes. Pulsed kuitika zvakadaro mano vanogona kusvika 1.2 Ka. Constant Magetsi dzimwe mhando dzinosvika 120 A. kwakadaro mano vane zvakawanda kuitika uye unongotaura akanaka. Vave vakabudirira kushandiswa mhuri midziyo yemagetsi uye maindasitiri Electronics.
