Dab tsi yog switching diode?

 

Hloov diode yog ib hom tshwj xeeb ntawm diode dav siv hauv hluav taws xob. Nws tuaj yeem hloov pauv sai ntawm lub xeev conduction mus rau lub xeev txiav tawm, thiab rov ua dua. Qhov kev hloov pauv no feem ntau hu ua "switching". Nws yog hu ua switching diode vim nws txoj kev siv tseem ceeb yog hloov hauv circuits.

 

Cov yam ntxwv ua haujlwm ntawm switching diodes

 

Cov yam ntxwv ua haujlwm ntawm kev hloov diodes txiav txim siab lawv txoj kev ntseeg tau raws li cov keyboards hauv circuits. Nws cov yam ntxwv ua haujlwm tuaj yeem piav qhia los ntawm kev nkag siab txog cov qauv ntawm lub diode.

 

Lub diode yog tsim los ntawm ob yam khoom - P-hom khoom thiab N-hom khoom - uas tau nias ua ke los tsim ib qho kev sib tshuam PN. Thaum lub PN hlws ris nyob rau hauv ib tug conductive lub xeev, tam sim no yuav dawb do ntws ntawm ob cov ntaub ntawv.

 

Thaum lub diode nyob rau hauv lub xeev txiav tawm, tsis muaj tam sim no ntws ntawm PN hlws ris. Hauv lub xeev no, cov khoom siv hluav taws xob tsuas tuaj yeem ntws hauv cov ntaub ntawv P-hom thiab tiv thaiv kom tsis txhob nkag mus rau N-hom khoom. Hauv lub xeev txiav tawm, qhov impedance ntawm diode yog siab heev, yog li nws tsis tuaj yeem dhau los ua ib qho kev hloov pauv hauv Circuit Court.

 

Lub xeev ua haujlwm ntawm kev hloov diodes txawv ntawm cov diodes zoo tib yam. Nws cov qauv tshwj xeeb tso cai rau nws yooj yim hloov ntawm ob lub xeev ua haujlwm. Hloov diodes muaj kev ceev dua thiab qis dua, ua rau lawv cov kev hloov pauv hauv circuits hloov tau yooj yim dua.

 

Daim ntawv thov teb ntawm Switching Diodes

 

Hloov diodes yog siv dav hauv ntau yam khoom siv hluav taws xob. Piv txwv li:

 

Hloov Circuit Court:Nyob rau hauv hluav taws xob circuits, switching diodes feem ntau yog siv los tswj switching circuits thiab tuaj yeem siv los ntsuas cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob me me.

 

Inverter:Nyob rau hauv ib qho inverter, cov yam ntxwv hloov pauv ntawm lub diode hloov pauv tuaj yeem pab hloov tam sim no ncaj qha mus rau qhov hloov pauv tam sim no.

 

PWM modulator:Los ntawm kev siv switching diodes, nws yog ib qho yooj yim los siv ib tug PWM modulator ua ib tug switching fais fab mov.
