Mehato ea Bohlokoa ho Khetho ea MOSFET

Matsatsing ana, ka tsoelopele e potlakileng ea mahlale le thekenoloji, li-semiconductors li sebelisoa liindastering tse ngata, tseo ho tsonaMOSFET e boetse e nkoa e le sesebelisoa se tloaelehileng haholo sa semiconductor, mohato o latelang ke ho utloisisa hore na phapang ke efe pakeng tsa litšobotsi tsa bipolar power crystal transistor le matla a tlhahiso ea MOSFET.

1, mokhoa oa ho sebetsa

MOSFET ke mosebetsi o hlokahalang ho ntšetsa pele motlakase oa ho sebetsa, litšoantšo tsa potoloho li hlalosa habonolo, li khothalletsa matla a manyenyane; matla a kristale transistor ke phallo ea matla ho khothaletsa moralo oa lenaneo o rarahane ho feta, ho nts'etsapele litlhaloso tsa khetho ea ho thata ho khothaletsa litlhaloso ho tla beha lebelo la phepelo ea motlakase ka botlalo.

2, lebelo le felletseng la phepelo ea motlakase

MOSFET e anngoeng ke mocheso e nyane, matla a phepelo ea phepelo ea motlakase a ka netefatsa hore ho feta 150KHz; matla a kristale transistor e na le nako e fokolang ea ho boloka tefiso ea mahala e fokotsa lebelo la phepelo ea motlakase, empa matla a eona a tsoang hangata ha a fete 50KHz.

3, Sebaka se sireletsehileng sa ho sebetsa

Matla MOSFET ha e na motheo oa bobeli, 'me sebaka se sireletsehileng sa ho sebetsa se pharaletse; matla a kristale transistor e na le boemo ba bobeli ba motheo, bo fokotsang sebaka se sireletsehileng sa ho sebetsa.

4, tlhokahalo ea ho sebetsa ha mokhanni oa motlakase o sebetsa

MatlaMOSFET ke ea mofuta o phahameng oa motlakase, tlhokahalo ea ho sebetsa ea conduction e phahame, ho na le coefficient e ntle ea mocheso; matla a kristale transistor ho sa tsotelehe hore na chelete e kae e hanana le tlhokahalo ea ho sebetsa ea motlakase, motlakase oa motlakase o sebetsang tlhokahalo e tlase, 'me o na le mocheso o mobe.

5, phallo e phahameng ea matla

MOSFET ea matla ho phepelo ea motlakase oa motlakase oa potoloho ea motlakase oa motlakase e le sesebelisoa sa phepelo ea motlakase, ts'ebetsong le mosebetsi o tsitsitseng bohareng, phallo e phahameng ea matla e tlaase; le matla a kristale transistor ts'ebetsong le mosebetsi o tsitsitseng bohareng, phallo e phahameng ea matla e phahame.

6, Litšenyehelo tsa sehlahisoa

Litsenyehelo tsa matla a MOSFET li phahame hanyane; theko ea matla a kristale triode e tlase hanyane.

7. Tšusumetso ea ho kenella

MOSFET ea matla ha e na phello ea ho kenella; matla a kristale transistor e na le phello ea ho kenella.

8, tahlehelo ea ho fetoha

MOSFET switching tahlehelo ha e kholo; matla a kristale transistor switching tahlehelo e batla e le kholo.

Ho phaella moo, boholo ba matla a MOSFET a kopantsoeng le ts'oaetso ea motlakase, athe bipolar power crystal transistor hoo e batlang e se na diode e kopanyang e ts'oarellang. ea mocha oa tšireletso ea phallo ea matla. Field effect tube in the shock absorbing diode nakong ea ts'ebetso eohle ea ho tima ka diode e akaretsang e le ho ba teng ha phallo ea morao-rao ea ho hlaphoheloa, ka nako ena diode ka lehlakoreng le leng ho nka drain - mohloli oa poleiti e bohareng ba ntho e kholo. ho phahama ha litlhoko tsa mosebetsi tsa motlakase o sebetsang, ka lehlakoreng le leng, le phallo ea morao-rao ea ho hlaphoheloa.
