E le lintho tse fetohang, MOSFET le IGBT hangata li hlaha lipotolohong tsa elektroniki.Li boetse li tšoana ka ponahalo le likarolo tsa sebopeho.Ke lumela hore batho ba bangata ba tla ipotsa hore na hobaneng lipotoloho tse ling li hloka ho sebelisa MOSFET, ha tse ling li etsa joalo.IGBT?
Phapano ke efe pakeng tsa bona?E 'ngoe,Olukeye tla araba lipotso tsa hau!
Ke eng aMOSFET?
MOSFET, lebitso le felletseng la Sechaena ke metal-oxide semiconductor field effect transistor.Hobane heke ea transistor ena ea phello ea tšimo e khethiloe ke lera le sireletsang, e boetse e bitsoa insulated heke field effect transistor.MOSFET e ka aroloa ka mefuta e 'meli: "N-mofuta" le "P-type" ho ea ka polarity ea "channel" ea eona (mojari ea sebetsang), eo hangata e bitsoang N MOSFET le P MOSFET.
MOSFET ka boeona e na le diode ea eona ea parasitic, e sebelisetsoang ho thibela MOSFET hore e se ke ea tuka ha VDD e le over-voltage.Hobane pele overvoltage e baka tšenyo ho MOSFET, diode e senyeha pele ebe e lebisa metsi a maholo fatše, kahoo a thibela MOSFET hore e se ke ea chesoa.
IGBT ke eng?
IGBT (Insulated Gate Bipolar Transistor) ke sesebelisoa sa semiconductor se kopantsoeng se entsoeng ka transistor le MOSFET.
Matshwao a potoloho a IGBT ha a so kopane.Ha u taka setšoantšo sa schematic, matšoao a triode le MOSFET hangata lia alima.Ka nako ena, o ka ahlola hore na ke IGBT kapa MOSFET ho latela mohlala o tšoailoeng setšoantšong sa schematic.
Ka nako e ts'oanang, u lokela ho ela hloko hore na IGBT e na le diode ea 'mele.Haeba e sa tšoauoa setšoantšong, ha ho bolele hore ha e eo.Ntle le haeba data ea semmuso e bolela ho fapaneng, diode ena e teng.Diode ea 'mele ka hare ho IGBT ha e na likokoana-hloko, empa e hlophisitsoe ka ho khetheha ho sireletsa mokokotlo o fokolang oa ho mamella motlakase oa IGBT.E boetse e bitsoa FWD (freewheeling diode).
Sebopeho sa ka hare ho tse peli se fapane
Lipalo tse tharo tsa MOSFET ke mohloli (S), drainage (D) le heke (G).
Lipalo tse tharo tsa IGBT ke mokelli (C), emitter (E) le heke (G).
IGBT e hahuoa ka ho kenyelletsa lera la tlatsetso ho drain ea MOSFET.Sebopeho sa bona sa ka hare ke se latelang:
Mabaka a ts'ebeliso ea bobeli a fapane
Mehaho ea ka hare ea MOSFET le IGBT e fapane, e leng se khethollang likarolo tsa tsona tsa kopo.
Ka lebaka la sebopeho sa MOSFET, hangata e ka fihlela motlakase o moholo, o ka fihlang KA, empa matla a prerequisite voltage standability ha a matla joalo ka IGBT.Libaka tsa eona tsa mantlha tsa ts'ebeliso ke ho chencha lisebelisoa tsa motlakase, li-ballasts, ho futhumala ha maqhubu a phahameng haholo, metjhini e chesehang ea maqhubu a holimo, lisebelisoa tsa motlakase tsa puisano le libaka tse ling tsa phepelo ea motlakase ea maqhubu a phahameng haholo.
IGBT e ka hlahisa matla a mangata, a hona joale le a motlakase, empa maqhubu ha a phahame haholo.Hajoale, lebelo la ho switjha ka thata la IGBT le ka fihla ho 100KHZ.IGBT e sebelisoa haholo mecheng ea welding, inverters, frequency converters, electroplating electrolytic power supply, ultrasonic induction heats le masimo a mang.
Likarolo tsa mantlha tsa MOSFET le IGBT
MOSFET e na le litšoaneleho tsa impedance e phahameng ea ho kenya letsoho, lebelo la ho fetola ka potlako, botsitso bo botle ba mocheso, hona joale ho laola motlakase, joalo-joalo Potolohong, e ka sebelisoa e le amplifier, switch ea elektronike le merero e meng.
E le mofuta o mocha oa sesebelisoa sa semiconductor ea elektronike, IGBT e na le litšobotsi tsa ho thibela ho kenya letsoho ho phahameng, matla a tlaase a matla a ho laola matla, potoloho e bonolo ea ho laola, ho hanyetsa matla a matla, le mamello e kholo ea hona joale, 'me e sebelisitsoe haholo lipotolohong tse sa tšoaneng tsa elektronike.
Potoloho e lekanang ea IGBT e bontšitsoe setšoantšong se ka tlase.IGBT ha e le hantle ke motsoako oa MOSFET le transistor.MOSFET e na le bothata ba khanyetso e phahameng, empa IGBT e hlola bofokoli bona.IGBT e ntse e na le matla a tlase a ho hanyetsa matla a phahameng..
Ka kakaretso, molemo oa MOSFET ke hore e na le litšobotsi tse ntle tsa maqhubu a holimo 'me e khona ho sebetsa ka makhetlo a makholo a kHz le ho fihla ho MHz.Bothata ke hore ho hanyetsa ho hoholo 'me tšebeliso ea matla e kholo maemong a phahameng a matla le a holimo.IGBT e sebetsa hantle maemong a tlase le maemong a matla a phahameng, e nang le matla a manyane a ho hanyetsa le matla a ho mamella a phahameng.
Khetha MOSFET kapa IGBT
Potolohong, hore na ho khetha MOSFET joalo ka tube ea switch ea matla kapa IGBT ke potso eo hangata baenjiniere ba kopanang le eona.Haeba lintlha tse joalo ka motlakase, hona joale, le matla a ho fetoha a sistimi a nahanoa, lintlha tse latelang li ka akaretsoa:
Hangata batho ba botsa: "Na MOSFET kapa IGBT e molemo?"Ha e le hantle, ha ho na phapang e ntle kapa e mpe pakeng tsa tse peli.Ntho ea bohlokoa ka ho fetisisa ke ho bona tšebeliso ea eona ea sebele.
Haeba u ntse u e-na le lipotso mabapi le phapang lipakeng tsa MOSFET le IGBT, u ka ikopanya le Olukey bakeng sa lintlha.
