Txheej txheem cej luam:

Qhov yooj yim kov hloov LED Circuit siv cov yam ntxwv tsis sib xws ntawm MOSFET.

MOSFET sawv cev rau Hlau-oxide-semiconductor field effect transistors. Nws yog lub ntsuas hluav taws xob tswj lub ntsiab lus uas tam sim no dhau los ntawm lub cuab yeej raug tswj los ntawm qhov hluav taws xob ntawm ob lub dav hlau.

Qhov koj yuav xav tau:

Lub zog MOSFET (IRFZ-44 NPN) (Lee's ID: 71211)

9V roj teeb (Lee's ID: 83741)

12V LED teeb (Lee tus ID: 5504)

Jumper xov hlau (Lee tus ID: 21802)

Breadboard (Lee tus ID: 10686)

9V roj teeb clip (Lee tus ID: 653)

Kauj Ruam 1: Cov Lus Qhia Ceev Kom Nco Ntsoov

Txij li thaum mosfet yog lub cuab yeej tswj hluav taws xob, nws nkag tau yooj yim rau kev tso tawm hluav taws xob thiab tuaj yeem raug puas tsuaj vim cov nqi zoo li qub ntws los ntawm lub dav hlau.

Hooking Up Wires rau MOSFET

Cias txuas lub dav hlau jumper mus rau ob txhais ceg ntawm MOSFET

Rau IRFZ-44:

Ob sab ceg yog lub qhov rooj dav dav (jumper dawb)

Qhov nruab nrab yog lub davhlau ya nyob twg (xim av jumper)

Txoj cai sab xis yog lub hauv paus dav hlau (txho jumper)

Txhawm rau qhib lub LED, tsuas yog kov lub davhlau ya nyob twg thiab lub davhlau ya nyob twg ntawm tib lub sijhawm.

Txhawm rau tua lub LED, kov lub hauv paus chaw thiab lub davhlau ya nyob twg ntawm SAME lub sijhawm

Cov laj thawj tom qab qhov haujlwm no yog cov yam ntxwv ntawm MOSFET:

Rau LED kom pom kev, MOSFET yuav tsum ua kom tiav, uas txhais tau tias Vds> Vgs-Vt. ua kom tiav ON

Ntawm qhov tod tes, kov lub qhov rooj thiab lub davhlau ya nyob twg yuav tig MOSFET tag nrho, vim tias nws tsis tuaj yeem ua raws qhov xav tau ntau dhau (Vov) qhov xav tau (Vov = Vgs - Vt, Vgs = 0V).

Yog tias koj muaj teeb meem qhib lub Circuit Court thiab kaw, ntub koj txhais tes yuav pab tau.
