Mapiritsi otenthetsera amagwiritsidwa ntchito kwambiri mu Power Supply Adapter, amatha kupangitsa kuti ma adapter amagetsi azikhala okhazikika.
Mtundu wa adapter yamagetsi
Malo opangira magetsi omwe amafunikira zida zopangira matenthedwe:
1. Chip chachikulu chamagetsi: Chip chachikulu chamagetsi apamwamba nthawi zambiri chimakhala ndi zofunika kwambiri pakuwotcha kutentha, monga magetsi a UPS, chifukwa champhamvu yake yoperekera mphamvu, chip chachikulu chiyenera kupirira kulimba mtima. makina onse, pa nthawi ino adzasonkhanitsa kutentha kwambiri, kotero timafunika matenthedwe zinthu conductive monga sing'anga wabwino matenthedwe conduction.
2. MOS transistor: MOS transistor ndiye gawo lalikulu kwambiri la kutentha kupatula chip chachikulu chamagetsi, chimafunika kugwiritsa ntchito mitundu yambiri yazinthu zopangira matenthedwe, monga pepala lotchinjiriza, mafuta otenthetsera, kapu yamafuta, ndi zina zambiri.
3. Transformer: Transformer ndi chida chosinthira mphamvu, kunyamula ntchito yotembenuka yamagetsi, yapano komanso kukana.Komabe, chifukwa cha ntchito yapadera ya thiransifoma, kugwiritsa ntchito zida zopangira matenthedwe kudzakhalanso ndi zofunikira zapadera.

Kugwiritsa ntchito pad yotenthetsera yotenthetsera: tsekani transistor ya MOS ndi sinki yotentha ya aluminiyamu yokhala ndi zomangira.
Kugwiritsa ntchito pad matenthedwe: Dzazani kusiyana kwa kulekerera pakati pa diode ndi sinki yotentha ya aluminiyamu, ndikusintha kutentha kwa diode kupita kumadzi otentha a aluminiyumu.
Adaputala yamagetsi yamagetsi II
Thermal pad pa pini ya zida zamagetsi kumbuyo kwa PCB.
Ntchito 1: Tumizani kutentha kwa zipangizo zamagetsi ku chivundikiro kuti chiwononge kutentha.
Ntchito 2: Phimbani zikhomo, pewani kutayikira ndi chivundikiro kuti zisawonongeke, tetezani ntchito ya zida zamagetsi.
