Zingaphi iiNgqondi eziNgaqondakaliyo ngoNikezo lwaMandla oMbane ozaziyo?

Yintoni umsebenzi ophambili wesekethe ye-EMI?

Umsebenzi wesekethe ye-EMI kukucoca zonke iintlobo zeempawu zokuphazamiseka kwigridi yamandla kunye nokuthintela igridi yamandla yokuphazamiseka kwe-frequency ephezulu eyenziwe yisekethe yokutshintsha amandla. I-EMI yinxalenye ebalulekileyo yesatifikethi se-CCC.

Ukungaqondi kakuhle umbane:

1: Amandla alinganisiweyo ombane kufuneka abe mancinci? Ukusetyenziswa kwamandla kugqitywa kukusetyenziswa kwamandla kweqonga, kwaye akunanto yakwenza nobungakanani bombane. Ukuba umbane umncinci kakhulu, awuyi kuqalisa.

2: Ubonelelo lwamandla lokukhetha imodyuli epheleleyo? Iqela leemodyuli lonke lijongene kuphela nocingo, ulawulo lwemigca olulula ngakumbi, kwaye okulungileyo nokubi akunanto yakwenza.

3: Ukungaqondi kakuhle izinga lokuguqulwa, Umbane oqhelekileyo, olinganiswe yi-450W. Ixabiso lokuguqulwa kwe-can yi-450W, kwaye i-80% lithetha ukuba ikhompyutha isebenzisa i-450W, ukusetyenziswa kwamandla okupheleleyo kwemitha yasekhaya yi-450÷80%=562W

4: Khetha amandla aphezulu alinganiswe yi-2000W, ixhala elincinci? Akukho budlelwane buthe ngqo phakathi kombane kunye namandla alinganisiweyo. Umbane kufuneka ube ngowohlobo oluthile kunye nomzekelo othile, kungekhona ngokujonga iiparameter zomphezulu.

Guqula i-AC voltage ephezulu yokufaka (AC) ibe yi-voltage yangoku echanekileyo esezantsi (DC) efunekayo, ekusebenzeni kwePC ngokusebenzisa itekhnoloji yokutshintsha i-frequency ephezulu.

Unolwazi olungakanani ngomgaqo osebenzayo wokunikezelwa kombane?

1: Yintoni umgaqo osisiseko wokusebenza kombane?

Guqula i-AC voltage ephezulu yokufaka (AC) ibe yi-voltage yangoku echanekileyo esezantsi (DC) efunekayo

Ukusebenza kwePC ngokusebenzisa iteknoloji yokutshintsha iifrikhwensi eziphezulu.

2. Iyintoni inkqubo yokusebenza kombane?

Xa i-mains ingena kumbane, iqala idlule kwi-choke coil kunye ne-capacitor filter ukuze isuse i-high frequency clutter kunye nesignali yokuphazamiseka, ize idlule kwi-rectification kunye ne-filter ukuze ifumane i-high voltage direct current. Emva koko idlule kwi-switching circuit iye kwi-high frequency pulsating DC, ize ithumele i-high frequency switching transformer step-down. Inxalenye ye-AC ephezulu iyahluzwa, ukuze isiphumo sokugqibela sibe ngamandla e-DC aphantsi e-voltage acocekileyo kwikhompyutha.

3. Yintoni umsebenzi ophambili wesekethe ye-EMI?

Indima yesekethe ye-EMI kukucoca zonke iintlobo zemiqondiso yokuphazamiseka evela kwigridi yamandla, kunye nokuthintela igridi yamandla yokuphazamiseka kwe-frequency ephezulu eyenziwe yisekethe yokutshintsha amandla.

I-EMI yinxalenye ebalulekileyo yesatifikethi seCCC.
