Ungakuvimbela kanjani ukwehluleka kwe-MOSFET

Isikhathi Sokuthumela: Jul-29-2024

Kulesi sigaba ezingeni lesicelo semboni, impahla ye-adaptha yedivayisi ye-elekthronikhi yokuqala ekleliswe kuqala. Futhi ngokusho kokusetshenziswa okuyinhloko kokubamba kwe-MOSFET, isidingo se-MOSFET esibekwe endaweni yesibili ibhodi lomama lekhompyutha, i-NB, i-adaptha yamandla echwepheshile yekhompyutha, isibonisi se-LCD nezinye izimpahla. Kanye nokuthuthuka kwezimo zezwe eziyisisekelo, amabhodi omama wekhompiyutha, ama-adaptha amandla ochwepheshe bekhompyutha, iziqapha ze-LCD ezidingweniAma-MOSFET kufanele idlulele ngale kwesimo sama-adaptha kagesi wabathengi.

Ngezansi i-MOS izizathu eziyisithupha ezinkulu ezingavumelekile.

1. Ukudilika komhlaba akuvumelekile (i-voltage esebenzayo ayivumelekile), okuvame ukubizwa ngokuthi ukuvuza phakathi komthombo we-voltage yokusebenza ye-BVdss idlula imanje elilinganiselwe le-MOSFET, nangaphezulu ukuze kwenziwe umsebenzi othile oholela ku-MOSFET engavumelekile.

2.I-SOA ayivumelekile (ukuhamba kwamandla akuvumelekile), kokubili endaweni ephephile yokusebenza ye-MOSFET ebangelwa okungavumelekile, ihlukaniswe nge-Id ngaphezu kwezicaciso zedivayisi futhi ayivumelekile futhi i-Id yayo inkulu kakhulu, ukuguga okuphakeme nokudabuka kwedivayisi ukunqwabelana okushisayo kwesikhathi eside okubangelwa okungavumelekile.

3. I-diode yomzimba engavumelekile. Kubhuloho, i-LLC nokunye okusebenzayo ku-diode yomzimba ukuze kuqhutshekwe nokuqhubeka kwe-topology yenethiwekhi, ngoba i-diode yomzimba ithintwa ukungasebenzi.

4. I-resonance yochungechunge engavumelekile. Kuhlelo lokusebenza oluwuchungechunge lwesixhumanisi, isango kanye namapharamitha we-parasitic wesekethe yokuphakelwa kwamandla aholela ekuguquguqukeni okubangelwa ukungasebenzi.

5. Ukufakwa kwe-electrostatic akuvumelekile. Ebusika nasekwindla, ngenxa yomzimba nemishini namathuluzi ngenxa yokungeniswa kwe-electrostatic okubangelwa idivayisi akuvumelekile.

6. I-voltage yesango engavumelekile. Ngenxa yokuthi isango laliyiziqongo ze-voltage esebenzayo engavamile, futhi ungqimba lwe-oxygen yesango lesango aluvumelekile.
