Esikhathini esinamandla sezakhi ze-elekthronikhi, ubuchwepheshe obuqhubekayo wezobuchwepheshe bubalulekile.Ishayela ukukhula kwezimboni.Thatha, ngokwesibonelo, i-Stmicroelectronics 'ukusika-onqenqemeni lwe-1350v IGBT Transistor Series.Lapha, sibona ukuthuthuka okuphawuleka ku-Design Margin, ukusebenza ngokwahlukana, kanye nokwethenjwa.Kutholakale ngokunyuka kwamandla kagesi wokuphuka nokushisa okusebenzayo, lezi zinto ezithuthukayo zibalulekile.Le ndatshana izohlola ukubaluleka kwaleli mpumelelo, ligxile emthonjeni walo we-multifacededed ezimweni ezingokoqobo.
Izici Zobuchwepheshe Nezinzuzo
Okokuqala, amapharamitha okusebenza we-IGBT Tramentistors amasha avela kuma-StmicroelectonIcs abone ukuthuthuka okumangalisayo.Ukugxuma ku-voltage voltage kuya ku-1350v kanye nokushisa okuphezulu okuphezulu okuphezulu kwama-175 ° C aphawuleka.Lokhu kusho ukusebenza okuthuthukile ezimweni ezimbi kakhulu.Intuthuko enjalo akuyona nje ukuthuthukiswa kwezobuchwepheshe;Baphinde basebenzise i-transistor's design margin, ukumelana nokuhlukahluka, futhi kuqinise ukuthembeka kwesikhathi eside.Lezi zimfanelo zibalulekile ekucindezelweni okuphezulu, okushisa kakhulu.
Ngemuva kwalokho, sineStyPower IH2 Series Igbt.Ukwethulwa kwayo kuphawula isinyathelo esibalulekile phambili ekusebenzeni kwamandla, ikakhulukazi ekuguqulweni kwamandla.Cabanga nge-voltage yayo ephansi ye-vce (SAT).Lokhu kuqinisekisa ukusetshenziswa kwamandla okuncane ku-'N 'ON' State.Ihlanganiswe ne-voltage yehla elincishisiwe kwi-diode yamahhala kanye namandla okuguqula okulungiselelwe, idivaysi idlula ekushintsheni kwe-quasi-resonance eyodwa ye-quasi-resonance kuwo wonke ama-000chz aya ngo-60khz.Ukuthuthuka okunjalo kokusebenza kahle kwamandla kubalulekile ekulondolozeni kwamandla nokuncishiswa kokuphuma.
Izimo Zokusebenza Ezisebenzayo
Ukuqina okusha kwe-IGBT ngokuhlukahluka kanye nokusebenza kahle kwamandla okuphezulu kunikela kulungele izinto zokufudumeza ze-electromagnetic.Lokhu kufaka izitofu zasekhishini, ama-oveno we-microwave microwave, namadivayisi wasendlini afana nabapheki belayisi.Kuhlelo lokusebenza lwe-2KW, amadivayisi amasha we-IGCT anganciphisa ukusetshenziswa kwamandla ngo-11%.Lokhu kunezinzuzo ezibonakalayo, njengokusetshenziswa kwamandla endlu encishisiwe kanye nezindleko zogesi eziphansi.
Ngokwengeziwe, umphumela wokushisa we-VCE (SAT) wokushisa we-coefreflent, kanye namapharamitha angaguquki, wenziwa lula izinqubo zokuklama.Isiza ekuhlanganiseni okufanayo kwamashubhu amaningi we-IGBT kuzilungiselelo ezinamandla aphezulu.Lesi sici sibalulekile ekuklameni kokubili ukuklama ukuqonda okubonakalayo kanye nokusebenza kwezindleko.
Ukutholakala Komkhiqizo
Amadivayisi amabili kulolu chungechunge, i-25A STGWA25IH135DF2 ne-35A STGWA35IH135DF2, afake ukukhiqizwa okukhulu.Zigcinwe kwiphakheji yamandla aphezulu e-247.Lokhu kupakisha kuguquguqukayo, kusiza ukuhlanganiswa okulula kube imishini ye-elekhthronikhi ehlukahlukene.
Ekuphetheni
Ukufingqa, ukwethulwa kwama-Stmicroelectonics 'New 1350v Igbt transistors kuyinto engokomfanekiso yezobuchwepheshe enemithelela emikhulu esebenzayo.Imaka umthelela omkhulu emkhakheni wezempi we-elekthronikhi, ikakhulukazi ekucindezelweni okuphezulu kwengcindezi ephezulu kanye nezindawo zokushisa eziphakeme.Njengoba lobu buchwepheshe buvela futhi bathola ukwamukelwa okubanzi, silindele ukufakaza eminye imininingwane.Lokhu kungenzeka kuthuthukise ukusebenza kwamandla, izinqubo zokuklama okuhambisanayo, futhi zithuthukise ukusebenza kwezindleko.
