A zamanin yau, tare da saurin haɓakar kimiyya da fasaha, ana amfani da semiconductor a cikin masana'antu da yawa, waɗandaMOSFET Ana kuma la'akari da na'urar semiconductor na gama gari, mataki na gaba shine fahimtar menene bambanci tsakanin halayen transistor na wutar lantarki na bipolar da ikon fitarwa MOSFET.
1, hanyar aiki
MOSFET shine aikin da ake buƙata don haɓaka ƙarfin wutar lantarki mai aiki, zane-zanen kewayawa ya bayyana sauƙi mai sauƙi, haɓaka ƙarfin ƙarami; ikon crystal transistor shine wutar lantarki don haɓaka ƙirar shirin ya fi rikitarwa, don haɓaka ƙayyadaddun zaɓi na mai wahala don haɓaka ƙayyadaddun ƙayyadaddun ƙayyadaddun bayanai zai lalata wutar lantarki gabaɗaya saurin sauyawa.
2, jimlar sauya saurin wutar lantarki
MOSFET da zafin jiki ya shafa yana da ƙananan, ikon samar da wutar lantarki mai sauya wutar lantarki zai iya tabbatar da cewa fiye da 150KHz; Power crystal transistor yana da ƴan ƙarancin lokacin ajiya na caji kyauta yana iyakance saurin sauyawar wutar lantarki, amma ƙarfin fitarwa gabaɗaya bai wuce 50KHz ba.
3. Safe wurin aiki
MOSFET Power ba shi da tushe na biyu, kuma wurin aiki mai aminci yana da faɗi; wutar lantarki crystal transistor yana da yanayin tushe na biyu, wanda ke iyakance amintaccen wurin aiki.
4, Electric shugaba aiki da ake bukata aiki irin ƙarfin lantarki
ƘarfiMOSFET nasa ne da babban nau'in wutar lantarki, buƙatun aiki na aiki da ƙarfin ƙarfin aiki ya fi girma, akwai ingantaccen madaidaicin zafin jiki; wutar lantarki crystal transistor komai nawa kudi ne juriya ga aiki bukata ƙarfin lantarki aiki, da lantarki madugu aiki da ake bukata ƙarfin lantarki aiki ne m, kuma yana da korau zafin jiki coefficient.
5, iyakar wutar lantarki
MOSFET Powerarfin wutar lantarki a cikin keɓancewar wutar lantarki mai ba da wutar lantarki ta keɓewar wutar lantarki azaman wutar lantarki, a cikin aiki da kwanciyar hankali aiki a tsakiya, matsakaicin wutar lantarki yana ƙasa; da wutar lantarki crystal transistor a cikin aiki da kuma barga aiki a tsakiyar, matsakaicin ƙarfin wutar lantarki ya fi girma.
6. Farashin samfur
Farashin wutar lantarki MOSFET ya ɗan fi girma; farashin ikon crystal triode ya ɗan ƙasa kaɗan.
7. Tasirin shiga ciki
MOSFET mai ƙarfi ba shi da tasirin shiga; ikon crystal transistor yana da tasirin shiga.
8. Canza hasara
MOSFET asarar canzawa ba ta da kyau; ikon crystal transistor canza hasara ne in mun gwada da girma.
Bugu da kari, mafi yawan iko MOSFET hadedde shock absorbing diode, yayin da bipolar ikon crystal transistor kusan babu hadedde shock absorbing diode.MOSFET girgiza sha diode kuma iya zama na duniya maganadisu domin sauya wutar lantarki da'irori maganadisu coils don ba da ikon factor kwana. na tashar aminci na kwararar wutar lantarki. Field sakamako tube a cikin girgiza sha diode a cikin dukan aiwatar da kashe tare da janar diode kamar yadda wanzuwar baya dawo da halin yanzu kwarara, a wannan lokaci da diode a daya hannun ya dauki sama magudana - tushen iyakacin duniya tabbatacce tsakiyar wani gwaji. tashi a cikin buƙatun aikin aiki na ƙarfin lantarki, a gefe guda, da juzu'in dawo da halin yanzu.
