M'makampani opanga zamagetsi ndi zamagetsi, kugwiritsa ntchitoZithunzi za MOSFET(metal-oxide-semiconductor field-effect transistors) yakhala chinthu chofunikira kwambiri pakuwongolera magwiridwe antchito amagetsi owongolera liwiro (ESR).Nkhaniyi iwunika momwe ma MOSFET amagwirira ntchito komanso momwe amathandizira pakuwongolera liwiro lamagetsi.
Mfundo yofunikira ya MOSFET:
MOSFET ndi chipangizo cha semiconductor chomwe chimatembenuza kapena kuzimitsa kutuluka kwa magetsi kudzera pamagetsi.Pamagetsi owongolera liwiro, ma MOSFET amagwiritsidwa ntchito ngati zinthu zosinthira kuti ziwongolere mayendedwe apano agalimoto, kulola kuwongolera bwino kwa liwiro la mota.
Kugwiritsa ntchito ma MOSFET pamagetsi owongolera liwiro:
Pogwiritsa ntchito liwiro lake labwino kwambiri komanso kuthekera kowongolera komwe kulipo, ma MOSFET amagwiritsidwa ntchito kwambiri pamagetsi owongolera liwiro pamabwalo a PWM (Pulse Width Modulation).Izi zimatsimikizira kuti mota imatha kugwira ntchito mokhazikika komanso moyenera pansi pamikhalidwe yosiyanasiyana yolemetsa.
Sankhani MOSFET yoyenera:
Mukamapanga chowongolera liwiro lamagetsi, kusankha MOSFET yoyenera ndikofunikira.Magawo oti muwaganizire akuphatikiza ma drain-source voltage (V_DS), kuchuluka kwachulukidwe kopitilira apo (I_D), liwiro losinthira, ndi magwiridwe antchito amafuta.
Zotsatirazi ndi ziwerengero zamagawo a WINSOK MOSFET mu zowongolera liwiro lamagetsi:

Konzani magwiridwe antchito amagetsi owongolera liwiro:
Mwa kukhathamiritsa magwiridwe antchito ndi kapangidwe ka MOSFET, magwiridwe antchito amagetsi othamanga amatha kupitilizidwanso.Izi zikuphatikizapo kuonetsetsa kuti kuzizira kokwanira, kusankha dera loyendetsa dalaivala yoyenera, ndikuwonetsetsa kuti zigawo zina zomwe zili muderali zingathenso kukwaniritsa zofunikira zogwirira ntchito.
