Ma charger (ma charger) amagawidwa molingana ndi ma frequency ogwirira ntchito a dera lopangidwira, lomwe lingagawidwe kukhala makina amagetsi pafupipafupi komanso makina othamanga kwambiri.Makina amtundu wamagetsi amapangidwa kutengera mfundo zachikhalidwe za analogi.Zida zamagetsi zamkati (monga ma transformers, inductors, capacitors, etc.)) Ndi zazikulu, nthawi zambiri pamakhala phokoso lochepa pothamanga ndi katundu wambiri, koma chitsanzochi chimakhala ndi mphamvu yotsutsa kukana pazikhalidwe zovuta za gridi chilengedwe, ndi kudalirika kwake. ndipo kukhazikika kumakhala kolimba kuposa makina othamanga kwambiri.
Makina othamanga kwambiri amagwiritsa ntchito microprocessor (CPU chip) ngati malo owongolera, ndikuwotcha mabwalo ovuta a analogi a hardware mu microprocessor kuwongolera magwiridwe antchito a UPS pogwiritsa ntchito pulogalamu yamapulogalamu.Chifukwa chake, voliyumu imachepetsedwa kwambiri.Kulemera kumachepetsedwa kwambiri, mtengo wopanga ndi wotsika, ndipo mtengo wogulitsa ndi wotsika kwambiri.Ma frequency a inverter pamakina apamwamba kwambiri amakhala pamwamba pa 20KHZ.Komabe, makina othamanga kwambiri amakhala osalolera bwino pansi pa gridi yamagetsi yamphamvu komanso chilengedwe, chomwe chili choyenera kukhazikika kwa gridi ndi fumbi.Environment ndi otsika kutentha ndi chinyezi.
Poyerekeza ndi makina othamanga kwambiri: makina othamanga kwambiri komanso ang'onoang'ono: kukula kwazing'ono, kulemera kwake, kugwiritsira ntchito bwino (mtengo wotsika mtengo), phokoso lochepa, loyenera ku maofesi, ntchito zotsika mtengo (mtengo wotsika pa mphamvu yomweyo) , kukhudzika kwa malo ndi chilengedwe Zing'onozing'ono, kunena kwake, mphamvu (SPIKE) ndi kuyankha kwakanthawi (TRANSIENT) chifukwa cha ma charger othamanga kwambiri pa makope, makina osindikizira a laser, ndi ma mota zimakhudzidwa mosavuta.
M'madera ovuta, makina opangira magetsi amatha kupereka chitetezo chotetezeka komanso chodalirika kuposa makina othamanga kwambiri.Nthawi zina monga chithandizo chamankhwala, zimafunika kuti chojambuliracho chikhale ndi chipangizo chodzipatula.Chifukwa chake, pamafakitale, zamankhwala, zoyendera ndi ntchito zina, makina amagetsi pafupipafupi ndi chisankho chabwinoko.Kusankhidwa kwa awiriwa kuyenera kuganiziridwa molingana ndi makasitomala osiyanasiyana, malo oyikapo, zinthu zolemetsa ndi zina.
Makhalidwe a makina amagetsi pafupipafupi ndi osavuta, ndipo mavuto ndi awa:
1. Kukula kwa zolowetsa ndi zotulutsa zotulutsa ndi zazikulu;
2. Kukula kwa fyuluta yotulutsa yomwe imagwiritsidwa ntchito kuthetsa ma harmonics apamwamba ndi aakulu;
3. Transformer ndi inductor zimapanga phokoso la audio;
4. Kuyankha kwamphamvu kwapang'onopang'ono komanso kusintha kwamphamvu kwa mains ndikovuta.
5. Kuchita bwino kochepa;
6. Kulowetsako kulibe mphamvu yokonza mphamvu, yomwe imayambitsa kuipitsa kwakukulu kwa gridi yamagetsi;
7. mtengo wapamwamba, makamaka kwa zitsanzo zazing'ono, sizingafanane ndi makina apamwamba kwambiri.
