Cholinga cha ma inductors amagetsi ndikuchepetsa kutayika kwakukulu mu pulogalamu yomwe imafuna kusintha kwamagetsi. Chigawo chamagetsi ichi chingagwiritsidwenso ntchito mu mphamvu ya maginito yopangidwa ndi koyilo yotchinga mwamphamvu kuti ilandire kapena kusunga mphamvu, kuchepetsa kutayika kwa chizindikiro pamapangidwe a dongosolo ndi fyuluta EMI phokoso. Mulingo wa kuyeza kwa inductance ndi henry (H).
Nawa tsatanetsatane wokhudza ma inductors amagetsi, omwe amapangidwa kuti apange mphamvu zambiri.
Mitundu ya Ma Inductor a Mphamvu Cholinga chachikulu cha chowotchera mphamvu ndikusunga kusasinthika mugawo lamagetsi lomwe lili ndi mphamvu yosuntha kapena magetsi. Mitundu yosiyanasiyana ya ma inductors amagawidwa m'magulu otsatirawa:

Opanga odziwika omwe amapanga ma inductors amagetsi akuphatikizapo Cooper Bussman, NIC Components, Sumida Electronics, TDK ndi Vishay. Ma inductors osiyanasiyana amagwiritsidwa ntchito pazinthu zinazake kutengera mawonekedwe aukadaulo monga magetsi, mphamvu yayikulu, mphamvu yokwera pamwamba (SMD) komanso kuchuluka kwapano. M'mapulogalamu omwe amafunikira kusintha magetsi pomwe mphamvu ikusungidwa ndipo mafunde a EMI amasefedwa, ndikofunikira kugwiritsa ntchito ma inductors a SMD.
Kugwiritsa Ntchito Mphamvu Yopangira Mphamvu Njira zazikulu zitatu zopangira mphamvu zomwe zingagwiritsidwe ntchito ndikusefa phokoso la EMI muzolowetsa za AC, kusefa maphokoso otsika pafupipafupi komanso kusunga mphamvu mu zosinthira DC-to-DC. Kusefa kumatengera mawonekedwe amitundu ina ya ma inductors amagetsi. Mayunitsi nthawi zambiri amathandizira ma ripple current komanso nsonga zapamwamba.
Momwe Mungasankhire Choyikitsira Mphamvu Choyenera Chifukwa cha kuchuluka kwa ma inductors amagetsi omwe alipo, ndikofunikira kusankha pakali pano pomwe pakatikati pamakhala komanso kupitilira kuchuluka kwazomwe mungagwiritse ntchito. Kukula, geometry, mphamvu ya kutentha ndi mawonekedwe opindika amakhalanso ndi gawo lalikulu pakusankha. Zina zowonjezera zimaphatikizapo milingo yamagetsi yama voltages ndi ma frequency ndi zofunika za inductance ndi zapano.
