I-AC capacitor engenamandla aphantsi kwii-inverters ze-motor traction ezinamandla aphezulu

I-AC capacitor engenamandla aphantsi kwii-inverters ze-motor drive ezisebenzisa amandla aphezulu Umfanekiso oPhambili

Inkcazo emfutshane:

Le capacitor yochungechunge lwe-AKMJ-S isetyenziselwa ukufunxa nokugcina amandla xa amandla e-AC ephezulu kunaleyo ifunekayo ngumthwalo we-DC, kunye nokubonelela ngamandla kumthwalo xa amandla e-AC ephantsi kunaleyo ifunekayo.

Uphawu

1. Iphakheji yetyesi yesinyithi, Itywinwe nge-resin;
2. Ukusetyenziswa kwenkqubo yamandla ombane aphezulu;
3. Isekethe yamandla aphezulu;
4. Ukuxhathisa umbane ophezulu, ngokuziphilisa ngokwawo;
5. Umbane ojikelezayo ophezulu, amandla aphezulu okumelana ne-dv / dt.

Umsebenzi

Kwisihluzo sokukhupha sombane we-DC, umsebenzi we-capacitor kukugcina ixabiso le-DC lingaguqukiyo ngokususa amandla amaninzi kangangoko kunokwenzeka.

Zonke ii-AC-DC converters, nokuba zizinto ezisetyenziswa ngomgca okanye zinento ethile yokutshintsha kuzo, zifuna indlela yokuthatha amandla ahlukeneyo kwicala le-AC kwaye zivelise amandla angaguqukiyo kwicala le-DC.
