Kev cuam tshuam los thiab cov kev daws teeb meem rau hloov lub zog hloov kho

Qhov zoo ntawm hloov lub zog hloov kho tau me me thiab kev hloov pauv loj, nws yuav ua haujlwm rau cov kev ua haujlwm loj thiab cov chaw ua haujlwm, cuam tshuam nrog cov haujlwm hauv hluav taws xob.

 

Muaj ob qho kev cuam tshuam ntawm kev cuam tshuam:

1. Qhov cuam tshuam ntawm cov kev cuam tshuam high-zaus los ntawm lub tshuab hloov hluav taws xob adapter nws tus kheej ntawm kev ua haujlwm ntawm cov hluav taws xob ib txwm;

2. Lub peev xwm ntawm lub zog hloov hluav taws xob adapter nws tus kheej kom cov kev cuam tshuam los ntawm cov cim cuam tshuam sab nraud thiab ua kom nws txoj haujlwm ib txwm, uas yog, kev tiv thaiv kev cuam tshuam. Lub zog hloov hluav taws xob adapter nrog kev cuam tshuam zoo thiab kev tiv thaiv kev cuam tshuam yuav muaj kev ruaj khov zoo dua.

 

Raws li daim ntawv los ntawm kev cuam tshuam, kev cuam tshuam ntawm hloov fais fab adapter tuaj yeem faib ua hluav taws xob hluav taws xob kev cuam tshuam (RFI). Muaj ntau ntau yam uas ua rau kev cuam tshuam cov peev txheej hauv qhov hloov hluav taws xob adapter. Cov hauv qab no yog ntau qhov chaw ntawm kev cuam tshuam.

 

1. Kev cuam tshuam tsim los ntawm lub hwj huam hloov lub raj thaum nws nyob hauv qhov hloov pauv lub xeev.

Lub Hwj Chim Hloov Tube hauv lub switching fais fab adapter ua haujlwm hauv lub tshuab hloov, thiab nws yuav tsim cov mem tes loj thiab cov mem tes tam sim no thaum ua haujlwm. Vim tias cov mem tes tam sim no thiab cov mem tes harterance hato, thiab vim tias qhov kev sib txuas ntawm lub raj xa hluav taws xob tau muab tso rau ntawm lub zog hluav taws xob tau muab tua tam sim no Ntawm lub tshuab hloov hluav taws xob ua adapter.

 

2. Kev cuam tshuam tshwm sim los ntawm kev rov ua kom rov qab cov yam ntxwv ntawm Diode.

Thaum Diode ua yeeb yam high-zaus kev kho kom zoo, vim muaj kev tshav dav hlau muaj peev xwm ploj mus tam sim ntawd, uas yuav ua rau qhov chaw rov qab los ntawm daim diode. Lub sijhawm no yog hu ua lub sijhawm rov qab rov qab. Nyob rau lub sijhawm no, vim muaj kev thim rov qab loj dua rau ntawm Diode, nws yuav tsim cov nyiaj loj thiab tsim qhov loj ntawm kev cuam tshuam.

 

Yog tias cov kev hloov pauv tam sim no Di / DT ntawm Diode loj dua thaum rov qab ua dua tshiab, yuav tsim hluav taws xob, uas yog lub suab nrov rov qab los ntawm Diode. Thaum Di / DT yog loj, nws yog hu ua kev rov zoo dua, thiab thaum DT yog me me, nws yog hu ua cov mos mos rov qab. Mos rov qab tuaj yeem ua tiav los ntawm kev nqus cov voj voog lossis cov tshuab ua haujlwm rov ua haujlwm. Mos rov qab yog ntawm cov txiaj ntsig zoo los txhim kho kev ntseeg tau ntawm kev hloov pauv fais fab tsim adapter thiab txo kev cuam tshuam. Txij li thaum schottky diodes tsis muaj cov cab kuj yuav tsis muaj cov txiaj ntsig ntxiv, cov suab rov qab yog qhov tsawg heev.

3. Kev cuam tshuam tsim los ntawm cov cua txias ntau zaus.

Qhov tam sim no nyob rau hauv qhov siab tshaj plaws Transformer windings cov ntaub ntawv sib nqus flux, tab sis ib feem me me ntawm glucety magnites los ntawm kev to taub zoo nkauj flux, uas yuav ua rau hluav taws xob cuam tshuam.

 

4. Kev cuam tshuam tsim los ntawm Rectifier Lim Circuit Court.

Lub ac tswv yim xaus ntawm hloov fais fab xa khoom adapter txuas nrog lub rectifier lim puag ncig. Lub conduction lub kaum sab xis ntawm Rectifier Diode yog qhov me me, uas ua rau lub ntsuas hluav taws xob ntawm lub rectifier tam sim no loj heev. Cov mem tes no zoo li cov ntaub ntawv tseem ceeb tam sim no tseem yuav ua rau cuam tshuam.

 

Kev cuam tshuam thiab daws ntawm hloov fais fab khoom adapter

 

Raws li cov xwm txheej uas ua kom muaj hluav taws xob compatibility, daws cov tshuab hluav taws xob tau sib xyaw ua ke ntawm peb sab nraud:

1) txo cov teeb meem cuam tshuam rau lub teeb meem los ntawm kev cuam tshuam

2) txiav tawm txoj kev tshaj tawm ntawm kev cuam tshuam teeb meem

3) Txhim kho cov kev tiv thaiv kev cuam tshuam ntawm kev cuam tshuam ntawm lub cev sib cuam tshuam

 

Rau sab nraud cuam tshuam tsim los ntawm hloov fais fab xa khoom adapter, xws li cov hluav taws xob sib txawv, hluav taws xob flortation interriation, thiab lwm yam. Ntawm ib sab tes, tus qauv siv cov kev siv nyiaj / tso zis thiab siv hluav taws xob hloov chaw thiab siv hluav taws xob hloov chaw thiab tswj cov qauv kev tswj hwm Ntawm qhov tod tes, daim thaiv thaiv cov nyhuv ntawm cov casing tuaj yeem tsim kom muaj zog, kev sib deev toast ntawm lub casing tuaj yeem ua tau zoo, thiab kev kho kom zoo rau kev ua haujlwm tau.

 

Rau kev tiv thaiv sab nraud, xws li kev tawm tsam thiab xob laim kev tiv thaiv, muaj peev xwm tiv thaiv ac tswv yim thiab dc tso zis chaw nres nkoj yuav tsum tau ua kom zoo. Rau kev tawm tsam hluav taws xob, kev sib xyaw ntawm cov varistor thiab cov roj paug roj paug tawm tuaj yeem siv los daws nws. Rau cov tshuab hluav taws xob tawm, TVS Tube thiab ntsuas kev sib raug zoo ntawm cov teeb meem me me thiab cov cuab yeej muaj peev xwm nce, lossis cov khoom siv cuam tshuam nrog kev cuam tshuam rau kev tiv thaiv kom daws tau nws. To reduce the internal interference of the power adapter, we should start from the following aspects: pay attention to the single-point grounding of digital circuits and analog circuits, and the single-point grounding of high-current circuits and low-current circuits, especially current and voltage sampling circuits, to reduce common impedance interference and reduce the impact of ground loops; Them sai sai rau qhov kev sib tw ntawm cov kab uas nyob ib sab thiab cov paib thaum uas xaim kom tsis txhob muaj crosstalk; txo av kab impedance; Txo thaj chaw ib puag ncig los ntawm cov kab hluav taws xob uas muaj ntau thiab cov kab muaj ntau dua, tshwj xeeb tshaj yog thawj lub transformer thiab hloov lub zog lim dej capectory; Txo thaj chaw ib puag ncig los ntawm cov zis rectifier Circuit Court thiab freeWheeling Diod thiab DC Lim Circuit Court; Txo cov dej xau taw qhia ntawm tus hloov pauv thiab xa cov hluav taws xob ntawm lub taub lim dej hluav taws xob; Siv cov lim capacitors nrog cov neeg muaj peev xwm siab dua, thiab lwm yam.

 

Nyob rau hauv cov nqe lus ntawm kev xa cov kev sib kis, tsim nyog tso cov tshuaj tiv thaiv siab, cov khoom siv hluav taws xob muaj peev xwm txhim kho cov kev cuam tshuam los tiv thaiv kev cuam tshuam; Lub teeb liab me me nyob ze rau cov casing yuav tsum tau ua kom zoo insulated thiab tau txais kev kho voltage; Lub tshav kub lub dab dej ntawm lub hwj chim ntaus ntawv thiab cov txheej txheem hluav taws xob tiv thaiv txheej ntawm lub qhov hluav taws xob loj yuav tsum tau ua kom zoo; Qhov loj hauv av nruab nrab ntawm cov koog tswj yuav tsum tau thaiv nrog lub phaj av; Ntawm lub ntsuas hluav taws xob, hluav taws xob sib txuas ntawm cov rectifiers thiab cov av hauv av yuav tsum tau txhim kho kev ruaj ntseg ntawm kev ua haujlwm sab hauv ntawm lub hwj chim adapter.

 

Peb tau tsim tsa peb tus kheej lub xov xwm hluav taws xob haum thiab tau cog lus rau kev tshawb fawb ntawm electromagnetic sib xyaw nyob rau hauv thaum ntxov ntawm kev hloov pauv lub zog hloov zog. Los ntawm cov zog kev tawm tswv yim thiab cov zis kev nyab xeeb tsim ntawm lub tshuab hluav taws xob hauv lub tshuab hluav taws xob, yog li cov lag luam kev tiv thaiv kev ruaj ntseg ntawm cov khoom siv hluav taws xob ruaj khov, yog li kev ntseeg tau ruaj khov, thiab kev ntseeg tau zoo. Qhov dav dav ac txawv Voltage ntau muab hloov hluav taws xob adapter kom ua haujlwm ib txwm poob, voltage hloov voltage thiab luv luv hluav taws xob cuam tshuam ntawm tag nrho cov tshuab.
