Maitiro ekudzivirira kutadza kweMOSFET

Nzira yekudzivirira sei MOSFET kukundikana

Nguva Yekutumira: Jul-29-2024

Panguva ino muindasitiri yekushandisa level, yekutanga chinzvimbo chevatengi zvemagetsi mudziyo adapta zvinhu. Uye maererano nekushandiswa kukuru kweMOSFET kubata, kudiwa kweMOSFET pachinzvimbo chechipiri ibhobhobhobho rekombuta, NB, komputa nyanzvi yemagetsi adapta, LCD kuratidza uye zvimwe zvinhu. Pamwe chete nebudiriro yemamiriro ekutanga epasirese, makomputa mamaboards, komputa nyanzvi yemagetsi adapta, LCD monitors pane zvinodiwaMOSFETs inofanirwa kupfuura mamiriro evatengi vemagetsi emagetsi.

Pazasi paneMOS zvikonzero zvitanhatu zvisina basa.

1. Landslide invalid (operating voltage invalid), iyo inowanzonzi kudonha pakati penzvimbo yeBVdss yekushandisa voltage inodarika yakayerwa ikozvino yeMOSFET, uye kupfuura kuita rimwe basa rinotungamira kune isingaite MOSFET.

2.SOA haina basa (kuyerera kwemagetsi hakusi kushanda), zvese pamusoro peMOSFET yakachengeteka nzvimbo yekushanda inokonzerwa neiyo isingashande, yakakamurwa kuita Id pamusoro peiyo mudziyo uye haina kushanda uye Id yayo yakakura kwazvo, yakakwira kupfeka uye kubvaruka kwechishandiso chenguva refu kuunganidzwa kwemafuta kunokonzerwa neisingashande.

3. Diode yemuviri isiriyo. Mubhiriji, LLC uye imwe inoshanda kune diode yemuviri kuita kuenderera kwenetiweki topology, nekuti diode yemuviri inobatwa nekusashanda.

4. Invalid series resonance. Muchikamu chekushandiswa kwechibatanidza, gedhi uye magetsi ekugadzirisa parasitic parasitic parameters zvinotungamirira kukuchinja kunokonzerwa nekusashanda.

5. Electrostatic induction haina kunaka. Munguva yechando nekudonha, nekuda kwemuviri uye muchina nemidziyo nekuda kweiyo electrostatic induction inokonzerwa nemudziyo haishande.

6. Gedhi regedhi risiri iro. Nekuti gedhi raive risingaite kushanda kwevoltage peaks, uye inotungamira kugedhi reokisijeni layer haishande.
