Tlhokahalo ea IGBT e ntse e phahama!Litheko li ntse li phahama, bareki ba ntse ba ts'oara thepa

Hajoale, indasteri ea semiconductor e ntse e le maemong a tlase,indasteri ea li-chipka kakaretso e tobane le khatello ea bareki ba ho khaola litaelo le theko ea lihlahisoa tse theohang, empa IGBT e lits'ebetsong tse peli tse tloaelehileng tsa likoloi tsa motlakase le tlhokahalo ea letsatsi la photovoltaic, ho potlaka ha thepa, khaello ea morao tjena ea boholo, eseng feela theko e nyolohetseng sky, indasteri ha se "theko e phahameng hakae ea bothata, empa ha e khone ho reka" ho hlalosa boemo ba khaello.

IGBT ke eona feela sehlopha sa likarolo tsa semiconductor se khonneng ho eketsa theko ea sona le ho feta tlhokahalo ka tsela eohle, haholo-holo ka lebaka la phepelo e fokolang ea lihlahisoa sethaleng sena, empa kaho ea bohlanya ea limela tsa matla a letsatsi, li-inverters tsa tsona li na le matla a maholo. tlhokahalo ea li-IGBT, hammoho le tlhokahalo e phahameng ea li-IGBT likoloing tsa motlakase, baetsi ba likoloi ba ka sehloohong ba 'nile ba li sebelisa khafetsa.

Ho tlalehoa hore IGBT ke ntho ea ho fetola matla, e nang le botumo ba "power electronics CPU", ke motlakase o tsamaisoang ke motlakase oa semiconductor o entsoeng ka BJT (bipolar junction transistor) le MOSFET (half oxygen effect transistor), e nang le melemo. e phahameng ea ho kenya letsoho, matla a phahameng a mamellang le ho theoha ha motlakase o tlase.

Ka ho phahama ha makoloi a macha a matla, tlhokahalo ea motlakase o phahameng e eketsehile haholo, 'me li-IGBT li fetohile sepheo sa nts'etsopele ea indasteri.Palo ea li-IGBT tse sebelisoang koloing ea motlakase e ka holimo ho makholo, e leng makhetlo a supileng ho isa ho a leshome a likoloi tsa khale tsa mafura.Lits'ebetsong tsa indasteri, ho na le li-motors tsa AC servo motors, li-inverters, phepelo ea matla a moea le a letsatsi le lisebelisoa tse ling tsa matla a matala, 'me karolong e phahameng ea motlakase, ho na le litselana tsa literene tse lebelo le tse ling tsa lipalangoang le lits'ebetso tsa marang-rang a motlakase.
