Pamene ukadaulo ukupita patsogolo, kufunikira kwa zida zamagetsi kukukulirakulira. Pokwaniritsa zofuna izi, ma frequency apamwamba amagetsi a DC akhala ukadaulo wofunikira. Kuchokera pazida zoyankhulirana ndi matelefoni kupita ku zida zamankhwala, kuchokera ku zowongolera zamafakitale kupita kumagetsi amunthu,ma frequency switching DC magetsizakhudza mbali zonse za moyo wathu. Ndiye, kodi magetsi osinthira pafupipafupi a DC ndi chiyani, ndipo amagwira ntchito bwanji?
Choyamba, tiyeni timvetsetse mfundo zake zoyambira. Magetsi osinthira pafupipafupi a DC ndi makina amagetsi omwe amatha kusinthira mphamvu zamagetsi zamagetsi (AC) kukhala voltage yokhazikika (DC). Poyerekeza ndi zowongolera zama mzere wachikhalidwe,magetsi osinthika kwambiri a DCperekani bwino kwambiri komanso kukula kochepa, kuwapangitsa kuti azigwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamagetsi.
Ntchito yamagetsi osinthika kwambiri a DCzimakhazikitsidwa makamaka pazigawo ziwiri zazikulu: chowongolera chosinthira ndi dera lowongolera. Makina osinthira amawongolera mphamvu yotulutsa mphamvu yamagetsi pogwiritsa ntchito zida zosinthira pafupipafupi (monga ma MOSFET), pomwe gawo lowongolera limayang'anira ma voliyumu otulutsa ndikusintha chowongolera kuti chikhale chokhazikika.
Pochita izi, mphamvu yolowera ya AC imakonzedwanso kukhala mphamvu ya DC kudzera pa chowongolera, kenako ndikuwongoleredwa ndi chowongolera, ndikukhazikika kudzera pagawo lowongolera. Izi imayenera mphamvu kutembenuka ndondomeko chimathandizamagetsi osinthika kwambiri a DCosati kungopereka mphamvu zokhazikika komanso kukwaniritsa kutembenuka kwamphamvu kwamphamvu pansi pamikhalidwe yosiyanasiyana yolemetsa.
Mapulogalamu amagetsi osinthika kwambiri a DCndi zosiyanasiyana kwambiri. M'munda wa zida zoyankhulirana, zimatha kupereka mphamvu zokhazikika komanso zodalirika kuti zitsimikizire kuti zida zoyankhulirana zikuyenda bwino. Pazida zamakompyuta, amatha kupereka chithandizo champhamvu chokhazikika kuzinthu monga ma CPU ndi makadi ojambula. M'munda wa zida zachipatala, amatha kupereka mphamvu zenizeni zopangira zida zamankhwala kuti zitsimikizire kuti chithandizo chamankhwala chikugwira ntchito bwino.
Powombetsa mkota,magetsi osinthika kwambiri a DCndi njira zamakono zosinthira mphamvu zamagetsi zogwira mtima, zokhazikika komanso zodalirika zomwe zakhala zofunikira kwambiri pazida zamakono zamakono. Ndi chitukuko chaukadaulo chomwe chikuchitika, akukhulupilira kuti magetsi osinthika kwambiri a DC atenga gawo lofunikira kwambiri m'tsogolomu, kubweretsa kumasuka komanso kuthekera m'miyoyo yathu.
