Pamene ukadaulo ukupita patsogolo, kufunikira kwa zida zamagetsi kukupitirira kukula. Pokwaniritsa zosowa izi, magetsi a DC osinthira pafupipafupi akhala ukadaulo wofunikira kwambiri. Kuyambira zida zolumikizirana mpaka zida zamankhwala, kuyambira zowongolera zamafakitale mpaka zamagetsi zaumwini,magetsi a DC osinthira pafupipafupi kwambirizakhudza mbali zonse za miyoyo yathu. Ndiye, kodi magetsi a DC osinthira pafupipafupi kwambiri ndi chiyani kwenikweni, ndipo amagwira ntchito bwanji?
Choyamba, tiyeni timvetse mfundo zake zoyambira. Mphamvu yamagetsi ya DC yosinthira pafupipafupi kwambiri ndi njira yamagetsi yomwe imatha kusintha mphamvu yamagetsi yolowera (AC) kukhala mphamvu yamagetsi yokhazikika (DC). Poyerekeza ndi owongolera achikhalidwe,magetsi a DC osinthira pafupipafupi kwambiriamapereka mphamvu zambiri komanso kukula kochepa, zomwe zimapangitsa kuti azigwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamagetsi.
Ntchito yamagetsi a DC osinthira pafupipafupi kwambiriChimakhazikitsidwa makamaka pazigawo ziwiri zofunika: chowongolera chosinthira ndi dera lowongolera. Chowongolera chosinthira chimawongolera mphamvu yotulutsa ya magetsi pogwiritsa ntchito zida zosinthira zamagetsi zamphamvu (monga ma MOSFET), pomwe dera lowongolera limawunika mphamvu yotulutsa ndikusintha chowongolera chosinthira kuti chisunge mphamvu yotulutsa yokhazikika.
Munjira imeneyi, mphamvu ya AC yolowera imakonzedwa koyamba kukhala mphamvu ya DC kudzera mu rectifier, kenako imayendetsedwa ndi switching regulator, ndikukhazikika kudzera mu control circuit. Njira yothandiza yosinthira mphamvu iyi imalolamagetsi a DC osinthira pafupipafupi kwambiriosati kungopereka mphamvu yokhazikika komanso kukwaniritsa kusintha kwa mphamvu moyenera pansi pa mikhalidwe yosiyanasiyana ya katundu.
Kugwiritsa ntchito kwamagetsi a DC osinthira pafupipafupi kwambirindi osiyanasiyana kwambiri. Pankhani ya zida zolumikizirana, zimatha kupereka mphamvu yokhazikika komanso yodalirika kuti zitsimikizire kuti zipangizo zolumikizirana zikugwira ntchito bwino. Pazida zamakompyuta, zimatha kupereka mphamvu yokhazikika kuzinthu monga ma CPU ndi makadi ojambula. Pankhani ya zida zamankhwala, zimatha kupereka mphamvu yeniyeni yogwiritsira ntchito zida zachipatala kuti zitsimikizire kuti chithandizo chamankhwala chikugwira ntchito bwino.
Powombetsa mkota,magetsi a DC osinthira pafupipafupi kwambirindi ukadaulo wogwira mtima, wokhazikika, komanso wodalirika wosinthira mphamvu womwe wakhala gawo lofunika kwambiri pazida zamakono zamagetsi. Ndi chitukuko chaukadaulo chomwe chikupitilira, akukhulupirira kuti magetsi a DC osinthira pafupipafupi adzakhala ndi gawo lofunika kwambiri mtsogolo, kubweretsa zosavuta komanso mwayi wambiri m'miyoyo yathu.
