Impamvu MOSFETS ifite akamaro muri Electronics igezweho
Wigeze wibaza uburyo terefone yawe ishobora gupakira imbaraga nyinshi zo kubara mumwanya muto? Igisubizo kiri muri kimwe mubintu byavumbuwe cyane muri electronics: MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor). Waba wishimisha, umunyeshuri, cyangwa ufite amatsiko gusa kubijyanye na elegitoroniki, gusobanukirwa MOSFETS ningirakamaro mugihe cya none.
NIKI CYIZA CYANE?
Tekereza MOSFET nkikintu gito cya elegitoroniki gishobora kugenzura amashanyarazi. Bitandukanye nubukanishi bwa gakondo, MOSFETs ntigira ibice byimuka kandi irashobora guhindura ibihumbi cyangwa miriyoni inshuro kumasegonda. Nibikorwa byibanze byubaka ibikoresho bya elegitoroniki bigezweho, kuva byoroheje bya LED bigenzura kugeza kuri microprocessor.
Imiterere shingiro ya MOSFET
| Terminal | Imikorere | Ikigereranyo |
|---|---|---|
| Irembo (G) | Igenzura imigendekere yubu | Nka kanda y'amazi |
| Inkomoko (S) | Aho ibyinjira byinjira | Nka soko y'amazi |
| Drain (D) | Aho bigezweho | Nkumugezi wamazi |
Ubwoko bwa MOSFETS: N-Umuyoboro vs P-Umuyoboro
MOSFETs ziza muburyo bubiri: N-umuyoboro na P-umuyoboro. Tekereza nk'ibikoresho byuzuzanya mu bikoresho bya elegitoroniki. N-umuyoboro MOSFETs ni nkibikoresho byiburyo (byinshi bisanzwe kandi bihendutse), mugihe P-umuyoboro MOSFETs nkibikoresho byibumoso (ntibisanzwe ariko nibyingenzi mubikorwa byihariye).
Itandukaniro ryingenzi
- N-umuyoboro: Hindura hamwe na voltage nziza yumuryango
- P-umuyoboro: Hindura hamwe na voltage mbi yumuryango
- N-umuyoboro: Mubisanzwe hasi RDS (kuri) kurwanya
- P-umuyoboro: Igishushanyo cyoroshye cyumuzingi mubihe bimwe
Porogaramu Rusange ya MOSFETS
MOSFETS ni ibintu byinshi bidasanzwe. Hano hari bimwe mubisanzwe:
- Amashanyarazi hamwe nubushakashatsi bwa voltage
- Abagenzuzi ba moteri hamwe na PWM
- LED abashoferi no kugenzura amatara
- Amajwi yongerera amajwi
- Ibikoresho bikoreshwa na bateri
Guhitamo MOSFET ikwiye
Guhitamo MOSFET ikwiye kubisabwa bisaba gusuzuma ibintu byinshi byingenzi:
| Parameter | Ibisobanuro | Urwego rusanzwe |
|---|---|---|
| VDS (max) | Umuvuduko ntarengwa w-isoko ya voltage | 20V - 800V |
| Indangamuntu (max) | Umuyoboro ntarengwa | 1A - 100A |
| RDS (kuri) | Kurwanya leta | 1mΩ - 100mΩ |
Amakosa Rusange yo Kwirinda
Iyo ukorana na MOSFETs, abitangira akenshi bakora aya makosa:
- Kwibagirwa kurinda amarembo
- Kwirengagiza imicungire yubushyuhe
- Irembo ritari ryiza rya voltage
- Imikorere mibi ya PCB
Ingingo Zigezweho
Ibitekerezo byo Gutwara Irembo
Gutwara amarembo neza ningirakamaro kubikorwa byiza bya MOSFET. Suzuma ibi bintu:
- Irembo ryinjira mumarembo (VGS (th))
- Amafaranga y'irembo (Qg)
- Guhindura ibisabwa
- Twara umuzenguruko wa topologiya
Gucunga Ubushyuhe
Imbaraga MOSFETs irashobora gutanga ubushyuhe bugaragara mugihe ikora. Gucunga neza ubushyuhe birimo:
- Guhitamo neza
- Ibikoresho byubushyuhe
- Ibitekerezo byo gutembera mu kirere
- Gukurikirana ubushyuhe
Ukeneye ibisubizo byumwuga MOSFET?
Kuri Olukey, dutanga intera nini ya MOSFETs yo murwego rwohejuru kubisabwa byose. Itsinda ryinzobere zacu zirashobora kugufasha guhitamo MOSFET nziza kubyo ukeneye byihariye.
Ibikoresho by'inyongera
Urashaka kumenya byinshi kuri MOSFETS? Reba ibi bikoresho bifite agaciro:
- Ibisobanuro birambuye
- Igishushanyo mbonera
- Ibisobanuro bya tekiniki
- Inzira zicyitegererezo
