Zingaki Izinga Lokungaqondi Kahle Ngokunikezwa Kwamandla Owaziyo?

Uyini umsebenzi oyinhloko wesekethe ye-EMI?

Umsebenzi wesekethe ye-EMI ukuhlunga zonke izinhlobo zezimpawu zokuphazamiseka ezivela kugridi yamandla nokuvimbela igridi yamandla yokushintshashintsha kwemvamisa ephezulu eyakhiwe yisekethe yokushintsha kwamandla. I-EMI iyingxenye ebalulekile yesitifiketi se-CCC.

Ukungaqondi kahle ukuphakelwa kukagesi:

1: Amandla alinganisiwe okunikezwa kwamandla kufanele abe mancane? Ukusetshenziswa kwamandla kunqunywa ukusetshenziswa kwamandla kwepulatifomu, futhi akunalutho oluphathelene nosayizi wokunikezwa kwamandla. Uma ukunikezwa kwamandla kuncane kakhulu, ngeke kuqalise.

2: Ukunikezwa kukagesi ukukhetha imojuli ephelele? Iqembu lonke lemojuli likhathalela kuphela ucingo, ukuphathwa komugqa okulula kakhulu, futhi okuhle noma okubi akunalutho olukwenza.

3: Ukungaqondi kahle izinga lokuguqulwa, Ukunikezwa kwamandla okuvamile, okulinganiselwe ku-450W. I-can output engu-450W, izinga lokuguqulwa elingu-80% lisho ukuthi ikhompyutha idla u-450W, ukusetshenziswa kwamandla okuphelele kwemitha yasekhaya kungu-450÷80%=562W

4: Khetha amandla aphezulu alinganiswe angu-2000W, ukukhathazeka okuncane? Akukho buhlobo obuqondile phakathi kokunikezwa kwamandla namandla alinganiswe. Ukunikezwa kwamandla kufanele kube okukhethekile kumkhiqizo othile kanye nemodeli ethile, hhayi ngokubheka amapharamitha obuso.

Guqula i-voltage ye-AC yokufaka ephezulu (i-AC) ibe yi-voltage yamanje eqondile ephansi (i-DC) edingekayo ekusebenzeni kwe-PC ngokusebenzisa ubuchwepheshe bokushintsha imvamisa ephezulu.

Ukwazi kangakanani ngesimiso sokusebenza sokuphakelwa kukagesi?

1: Iyini isimiso esiyisisekelo sokusebenza kokunikezwa kwamandla?

Guqula i-voltage ephezulu ye-AC yokufaka (AC) ibe yi-voltage yamanje eqondile ephansi (DC) edingekayo

Ukusebenza kwe-PC ngokusebenzisa ubuchwepheshe bokushintsha imvamisa ephezulu.

2. Iyini inqubo yokusebenza kokunikezwa kukagesi?

Uma amapayipi amakhulu engena kugesi, aqala adlule ku-choke coil kanye nesihlungi se-capacitor ukuze asuse ukuxinana kwamafrikhwensi aphezulu kanye nesignali yokuphazamiseka, bese edlula ekulungisweni nasekuhlungeni ukuze kutholakale i-voltage ephezulu yamanje. Bese kuthi ngokusebenzisa isekethe yokushintsha iye ku-DC ephezulu eshaya ngamandla, bese ithumela i-transformer eshintsha ngamandla aphezulu. Ingxenye ye-AC ephezulu iyahlungwa, ukuze umphumela wokugcina ube amandla e-DC aphansi ahlanzekile ekhompyutha.

3. Uyini umsebenzi oyinhloko wesekethe ye-EMI?

Indima yesekethe ye-EMI ukuhlunga zonke izinhlobo zezimpawu zokuphazamiseka ezivela kugridi yamandla, nokuvimbela igridi yamandla yokushintshana kwesiteshi sokuphazamiseka kwemvamisa ephezulu eyakhiwe yisekethe yokushintsha kwamandla.

I-EMI iyingxenye ebalulekile yesitifiketi se-CCC.
