Dab tsi yuav tsum yog qhov tsawg kawg nkaus ntawm lub zog rau zener diode rau lub voj voog no ua haujlwm?

Hauv kev siv thev naus laus zis thev naus laus zis, kev tsim hluav taws xob tsim hluav taws xob yuav tsum xav txog qhov tsis muaj ntawm cov khoom siv thiab lawv cov kev sib koom ua ke. Ntawm lawv, rau kev tsim ntawm zener diode circuits, nws yog ib qho tsim nyog los txiav txim siab qhov tsawg kawg nkaus lub zog ntsuas qhov xav tau rau lub voj voog. Tom ntej no, peb yuav tham txog qhov teeb meem no kom ntxaws.

Ua ntej, peb yuav tsum nkag siab tias zener diodes yog dab tsi. Nws yog diode nrog tshwj xeeb thim rov qab tawg voltage muaj peev xwm thiab muaj zog voltage stabilization yam ntxwv. Thaum qhov hluav taws xob rov qab mus txog qhov teeb tsa tus nqi, nws tsim cov qauv transistor tshwj xeeb raws li adiabatic tej yam kev mob, ua rau tam sim no dhau mus thiab ua tiav kev ua haujlwm ruaj khov. Yog li ntawd, peb feem ntau siv zener diodes rau circuits uas yuav tsum tau ruaj khov voltage, xws li cov khoom siv hluav taws xob, hluav taws xob tswj Circuit Court, thiab lwm yam.

Hauv zener diode circuits, peb yuav tsum txiav txim siab qhov tsawg kawg nkaus lub zog ntsuas ntawm lub cuab yeej. Qhov no yog vim hais tias yog hais tias lub hwj chim ntsuam xyuas ntawm cov xaiv zener diode yog heev me me, nws yuav overheat thiab ua rau kev puas tsuaj thaum nws tshaj nws lub hwj chim tiag tiag nyob rau hauv nws ib txwm ua hauj lwm ntau yam. Thiab qhov ntsuas hluav taws xob no feem ntau yog nyob ntawm qhov siab tshaj plaws tam sim no thiab qhov siab tshaj qhov xav tau los ntawm zener diode, thiab yuav tsum ua raws li cov qauv hauv qab no:

Pmin=Vzener * Imax

Ntawm lawv, Pmin yog qhov tsawg kawg nkaus qhov ntsuas hluav taws xob xav tau los ntawm Circuit Court, Vzener yog qhov ruaj khov rov qab voltage tus nqi ntawm zener diode, thiab Imax yog qhov siab tshaj plaws tam sim no tus nqi xav tau los ntawm Circuit Court.

Hauv kev siv thiab kev sim, peb yuav tsum tau them nyiaj tshwj xeeb rau kev ua haujlwm siab tshaj plaws thiab lub zog hluav taws xob ntawm lub zener diode hauv Circuit Court. Yog tias qhov siab tshaj plaws ua haujlwm siab tshaj qhov ntsuas kev ua haujlwm ntawm lub zener diode, nws yuav ua rau zener diode tshaj nws lub peev xwm thiab puas; Yog hais tias lub hwj chim mov voltage ntau dua qhov ruaj khov rov qab voltage ntawm zener diode, zener diode yuav tsis ua haujlwm vim nws raug yuam kom tawg. Peb yuav tsum tau xyuam xim txaus rau ob yam no hauv kev tsim hluav taws xob kom ntseeg tau tias txhua lub cuab yeej tuaj yeem ua haujlwm tau zoo.

Tsis tas li ntawd, peb kuj yuav tsum tau them sai sai rau qhov ntsuas kub ntawm lub zener diode. Vim tias qhov kub thiab txias nyob ntawm qhov kev sib tsoo hauv lub zener diodes, thaum qhov kub siab tshaj nws qhov ntsuas kub ntau, nws cov yam ntxwv voltage stabilizing yuav raug txo kom tsawg, yog li cuam tshuam rau kev ruaj ntseg thiab kev nyab xeeb ntawm Circuit Court.
