Qhov zoo thiab cov kev nyuaj ntawm diodes hauv kev them nyiaj ceev ceev

1, qhov zoo ntawm diodes hauv kev them nyiaj ceev ceev
Kev siv hluav taws xob hloov kho
Ib qho ntawm cov haujlwm tseem ceeb ntawm diodes hauv kev them nyiaj ceev nrawm, uas hloov dua tshiab hloov tam sim no. Thaum lub sij hawm kho cov txheej txheem, diodes tuaj yeem hloov kho hluav taws xob kom zoo los ntawm ib qho kev taw qhia rau lwm qhov, txo lub zog poob. Tshwj xeeb tshaj yog nyob rau hauv high - zaus hloov kho lub zog hloov kho hluav taws xob (xws li kev siv hluav taws xob rov qab zoo thiab txo kev siv hluav taws xob thaum lub zog them.
Voltage thiab kev tiv thaiv tam sim no
Diodes muaj unidirectional conduction, uas ua rau lawv muab voltage thiab kev tiv thaiv tam sim no nyob rau hauv kev voj voog. Hauv kev them nyiaj ceev ceev hauv Circuit Court, thaum rov qab ua haujlwm tam sim no tshwm sim los tiv thaiv qhov tam sim no los ntawm kev tiv thaiv lwm yam hauv Circuit Court ntawm kev puas tsuaj. Qhov kev tiv thaiv kev tiv thaiv no yog qhov tseem ceeb heev rau kev ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov nqi them rau Circuit Court.
Cov lus teb ceev ceev
Kev rov qab nrawm deses muaj lub sijhawm luv luv rov qab thiab tuaj yeem rov qab los ntawm lub xeev mus rau hauv lub xeev. Tus xeeb ceem no ua rau kev hloov pauv sai sai teb cov khoom siv tam sim no, ua haujlwm ruaj khov hloov chaw ntawm txoj kev them Circuit Court. Ib qho ntxiv, kev teb nrawm nrawm kuj tseem pab txo cov hluav taws xob hauv hluav taws xob (EMI) thaum lub sijhawm them nyiaj thiab txhim kho kev ua haujlwm.
Miniaturization thiab Kev Sib Koom Tes
Nrog kev nce qib nruam ntawm semiconductor thev naus laus zis, diodes tab tom txhim kho ntawm miniaturization thiab kev sib koom ua ke. Miniaturized diodes tuaj yeem txuag cov chaw muag nkoj hauv Circuit Court, txo qhov hnyav thiab qhov hnyav ntawm cov neeg foob, thiab txhim kho qhov tseem ceeb. Kev sib xyaw ua ke diodes tuaj yeem ntim tau ua ke nrog lwm cov tib yam ntawm ib qho nti, kev sib txuas kev tsim qauv thiab tsim cov nqi kev tsim khoom thiab txo tus nqi.
2, Kev sib tw ntawm diodes hauv kev them nyiaj ceev ceev
Kev Tswj Cov Thermal
Thaum lub sijhawm them nyiaj ceev ceev, diro generates ib qho nyiaj ntawm cov cua sov. Raws li lub zog them nyiaj nce, lub cua kub tiam ntawm diode yuav nce raws li. Yog tias kev tswj hwm thermal yog tsis raug, daim diode yuav raug puas vim muaj kev kub ntxhov, yog li cuam tshuam qhov ruaj khov thiab kev nyab xeeb ntawm kev them hluav taws xob. Yog li ntawd, yuav ua li cas zoo li kev tswj cov cua sov kom ntseeg tau tias qhov kev ua haujlwm tseem ceeb yog qhov teeb meem tseem ceeb uas yuav tsum tau hais daws cov qauv ntawm kev them se nrawm.
Rov qab rov qab tshwj xeeb
Txawm hais tias kev rov qab sai diodes muaj sijhawm luv luv, lawv cov yam ntxwv rov qab rov qab yuav tseem ceeb rau kev them nyiaj nrawm rau qee kis. Tshwj xeeb tshaj yog nyob rau hauv high - zaus hloov hluav taws xob cov khoom siv, rov qab lub sijhawm rov qab los yuav cuam tshuam rau kev them nyiaj rov qab. Yog li ntawd, yuav ua li cas thiaj zoo rov qab tus yam ntxwv rov qab los ntawm dodes thiab txuas ntxiv txhim kho kev them nyiaj txuas ntxiv tam sim no yog kev tshawb fawb kub.
Voltage Cov Kab Kub No
Hauv kev them nyiaj ceev nrawm, dodees yuav tsum tau tiv thaiv siab siab. Nrog kev nce ntawm them voltage, cov yuav tsum tau muaj dua tau muab tso rau pem hauv ntej rau txoj kev ntsuas hluav taws xob. Yog hais tias lub voltage nqa muaj peev xwm ntawm diode tsis txaus, nws yuav ua rau muaj kev puas tsuaj lossis kev puas tsuaj, yog li cuam tshuam kev ua haujlwm ib txwm muaj ntawm kev them nyiaj Circuit Court. Yog li ntawd, thaum xaiv diodes, nws yog ib qho tsim nyog los xav txog lawv cov kev tso siab rau kom ntseeg tau tias lawv tseem tuaj yeem ua haujlwm nyob rau hauv voltage ib puag ncig.
Tus nqi thiab kev cia siab
Txawm hais tias Diodes muaj ntau yam zoo hauv kev them nyiaj ceev nrawm, lawv cov nqi thiab kev ntseeg tau yog qhov tseem ceeb uas yuav tsum tau txiav txim siab. Kev ua tau zoo diodes feem ntau tuaj ntawm tus nqi siab dua, uas yuav nce tus nqi ntawm lub charger. Lub caij no, kev ntseeg tau ntawm ddayiab tseem yog qhov tseem ceeb rau kev pabcuam lub neej thiab kev ua haujlwm ntawm cov foob. Therefore, when designing and manufacturing fast charging circuits, it is necessary to strike a balance between cost and reliability, and choose a cost-effective diode solution.
3, cov tswv yim thiab cov kev cia siab rau kev sib tw cov nyom
Cov tswv yim nram qab no tuaj yeem raug xa los daws cov kev cov nyom ntawm donies hauv kev them nyiaj ceev nrawm:
Kev Tsim Kho Kom Zoo Thermal: Los ntawm kev txhim kho cov qauv cua sov dissipation, cov cua sov disscation muaj peev xwm thiab nws ua haujlwm kub tau raug txo kom tsawg.
Kev txhim kho diodes tshiab: tshawb txog cov ntaub ntawv Diode thiab thev naus laus zis tshiab, thiab qis dua cov cua sov kom tau raws li cov kev xav tau ntawm kev them nyiaj ceev ceev.
Txhim kho kev koom ua ke: los ntawm kev tsim qauv sib xyaw ua ke nrog lwm cov khoom sib xyaw ua ke, txo qhov chaw mos thaum txhim kho kev cia siab thiab ua tau zoo.
Kev sim dua kev xeem thiab kev txheeb xyuas: Hauv kev tsim qauv thiab kev pov thawj ntawm diodes kom ntseeg tau tias lawv cov kev ua tau zoo los ua kom zoo thiab kev ntseeg tau ntawm cov neeg siv hluav taws xob.
