IGBT (Insulated Gate Bipolar Transistor) ndi MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) ndi zida ziwiri zodziwika bwino za semiconductor zomwe zimagwiritsidwa ntchito kwambiri pamagetsi amagetsi. Ngakhale kuti zonsezi ndi zigawo zofunika pa ntchito zosiyanasiyana, zimasiyana kwambiri m'mbali zingapo. Pansipa pali kusiyana kwakukulu pakati pa IGBT ndi MOSFET:
1. Mfundo Yogwira Ntchito
- IGBT: IGBT imaphatikiza mawonekedwe a BJT (Bipolar Junction Transistor) ndi MOSFET, ndikupangitsa kuti ikhale chipangizo chosakanizidwa. Imayang'anira maziko a BJT kudzera pamagetsi a chipata cha MOSFET, yomwe imayendetsa kayendedwe ka BJT ndi kudula. Ngakhale ma conduction ndi ma cutoff a IGBT ndi ovuta, amakhala ndi kutayika kwamagetsi otsika komanso kulolerana kwamagetsi.
- MOSFET: MOSFET ndi transistor yogwira ntchito pamunda yomwe imayang'anira zomwe zikuchitika mu semiconductor kudzera pachipata chamagetsi. Pamene voteji pachipata kuposa gwero voteji, ndi conductive wosanjikiza mawonekedwe, kulola panopa kuyenda. Mosiyana ndi zimenezi, pamene magetsi a chipata ali pansi pa chiwombankhanga, gawo la conductive limatha, ndipo zamakono sizingayende. Kugwira ntchito kwa MOSFET ndikosavuta, ndikuthamanga kwachangu.
2. Malo Ogwiritsira Ntchito
- IGBT: Chifukwa cha kulekerera kwamphamvu kwamagetsi, kutsika kwamagetsi otsika, komanso kusintha kwachangu, IGBT ndiyoyenera kugwiritsa ntchito mphamvu zambiri, zotayika pang'ono monga ma inverters, ma driver, makina owotcherera, ndi magetsi osasokoneza (UPS) . M'mapulogalamuwa, IGBT imayang'anira bwino magwiridwe antchito amagetsi apamwamba komanso amakono.
- MOSFET: MOSFET, ndikuyankha kwake mwachangu, kukana kwambiri, kusintha kokhazikika, komanso mtengo wotsika, imagwiritsidwa ntchito kwambiri pamagetsi otsika, osinthira mwachangu monga magetsi osinthira, kuyatsa, zokulitsa mawu, ndi mabwalo omveka. . MOSFET imagwira ntchito bwino kwambiri pamagetsi otsika komanso otsika mphamvu.
3. Makhalidwe Antchito
- IGBT: IGBT imapambana pamagetsi apamwamba, apamwamba-panopa ntchito chifukwa cha mphamvu yake yogwiritsira ntchito mphamvu zazikulu ndi kutayika kochepa kwa conduction, koma imakhala ndi maulendo osintha pang'onopang'ono poyerekeza ndi MOSFETs.
- MOSFET: Ma MOSFET amadziwika ndi liwiro losinthira mwachangu, kugwiritsa ntchito bwino kwambiri pamagetsi otsika, komanso kutsika kwamphamvu kwamagetsi pama frequency apamwamba.
4. Kusinthana
IGBT ndi MOSFET zidapangidwa ndikugwiritsidwa ntchito pazolinga zosiyanasiyana ndipo sizingasinthidwe. Chisankho cha chipangizo chomwe chidzagwiritse ntchito zimatengera kagwiritsidwe ntchito kake, zofunikira zogwirira ntchito, komanso mtengo wake.
Mapeto
IGBT ndi MOSFET zimasiyana kwambiri malinga ndi mfundo zogwirira ntchito, malo ogwiritsira ntchito, komanso mawonekedwe a magwiridwe antchito. Kumvetsetsa kusiyana kumeneku kumathandiza posankha chipangizo choyenera cha mapangidwe amagetsi amagetsi, kuonetsetsa kuti ntchito yabwino ndi yotsika mtengo.
