Kodi mukudziwa kusamvetsetsana kangati pa magetsi?

Kodi ntchito yaikulu ya EMI circuit ndi chiyani?

Ntchito ya EMI circuit ndikusefa mitundu yonse ya zizindikiro zosokoneza kuchokera ku power grid ndikuletsa power grid yosokoneza ma frequency ambiri yopangidwa ndi power switch circuit. EMI ndi gawo lofunikira la CCC certification.

Kusamvetsetsa bwino za magetsi:

1: Mphamvu yovomerezeka ya magetsi iyenera kukhala yochepa? Kugwiritsa ntchito mphamvu kumatsimikiziridwa ndi momwe magetsi amagwiritsidwira ntchito pa nsanja, ndipo sikukhudzana ndi kukula kwa magetsi. Ngati magetsi ndi ochepa kwambiri, sangathe kuyatsa.

2: Kupereka magetsi kuti musankhe gawo lonse? Gulu lonse la ma module limangoganizira za waya, kasamalidwe ka mzere kosavuta, ndipo chabwino kapena choipa sichikugwirizana ndi chilichonse.

3: Kusamvetsetsa kuchuluka kwa magetsi omwe agwiritsidwa ntchito, mphamvu yamagetsi yachizolowezi, yomwe yapatsidwa 450W. Mphamvu yamagetsi yomwe imachokera ku 450W, 80% ya mphamvu yamagetsi yomwe ikugwiritsidwa ntchito imatanthauza kuti kompyuta imagwiritsa ntchito 450W, mphamvu yonse yomwe imagwiritsidwa ntchito pa mita yamagetsi ndi 450÷80%=562W.

4: Sankhani mphamvu yayikulu kwambiri ya 2000W, nkhawa yaying'ono? Palibe ubale wolunjika pakati pa magetsi ndi mphamvu yovomerezeka. Mphamvu iyenera kukhala yeniyeni kwa mtundu winawake ndi mtundu winawake, osati poyang'ana magawo a pamwamba.

Sinthani mphamvu yamagetsi ya AC (AC) yapamwamba kwambiri kukhala mphamvu yamagetsi yotsika (DC) yofunikira pakugwiritsa ntchito PC pogwiritsa ntchito ukadaulo wosinthira pafupipafupi.

Kodi mukudziwa zambiri za mfundo yogwirira ntchito ya magetsi?

1: Kodi mfundo yoyambira yogwirira ntchito yamagetsi ndi iti?

Sinthani voliyumu yapamwamba ya AC (AC) kukhala voliyumu yotsika ya Direct current (DC) yofunikira pa

Kugwiritsa ntchito kompyuta pogwiritsa ntchito ukadaulo wosinthira pafupipafupi kwambiri.

2. Kodi njira yogwirira ntchito ya magetsi ndi yotani?

Pamene mains akulowa mumagetsi, choyamba amadutsa mu choke coil ndi capacitor fyuluta kuti achotse kusokonezeka kwa ma frequency ndi chizindikiro chosokoneza, kenako amadutsa mu rectification ndi filtering kuti apeze high voltage direct current. Kenako kudzera mu switching circuit kupita ku high frequency pulsating DC, kenako amatumiza high frequency switching transformer step-down. Gawo la high-frequency AC limasefedwa, kotero kuti output yomaliza ikhale yangwiro ya low-voltage DC ya kompyuta.

3. Kodi ntchito yaikulu ya EMI circuit ndi yotani?

Ntchito ya EMI circuit ndikusefa mitundu yonse ya zizindikiro zosokoneza zomwe zimachokera ku power grid, ndikuletsa power grid yosokoneza ma frequency ambiri yomwe imapangidwa ndi power switch circuit.

EMI ndi gawo lofunikira la satifiketi ya CCC.
