Low-inductance AC capacitor mo inverters ta'avale afi eletise maualuga

Low-inductance AC capacitor mo le malosi maualuga traction afi inverters Fa'aalia Ata

Fa'amatalaga Puupuu:

O lenei AKMJ-S faasologa capacitor e faʻaaogaina e faʻafefe ma teuina le malosi pe a maualuga le mana AC nai lo le mea e manaʻomia e le uta DC, ma tuʻuina atu le malosi i le uta pe a maualalo le mana AC nai lo le mea e manaʻomia.

Fa'aaliga

1. afifi pusa uamea, Faamaufaailogaina i resini;
2. Fa'aogaina o le eletise eletise maualuga;
3. Lisi eletise maualuga;
4. Teteʻe i le maualuga voltage, faʻatasi ai ma le faʻamaloloina o ia lava;
5. Galue maualuga i le taimi nei, maualuga dv / dt gafatia gafatia.

Galuega

I totonu o le faamama o le eletise DC, o le galuega a le capacitor o le tausia lea o se tau DC faifai pea e ala i le aveesea o le tele o le eletise pe a mafai.

O AC-DC converters uma, pe o ni sapalai laina po'o le i ai o se ituaiga o elemene fesuia'i ia i latou, e mana'omia se masini e ave ai le malosiaga fesuisuiai i le itu AC ma maua ai se malosiaga faifaipea i le itu DC.
