Kanema wazitsulo wa IGBT Snubber capacitor

Kufotokozera Kwachidule:

1. Chophimba chapulasitiki, Chosindikizidwa ndi utomoni;

2. Tin-yokutidwa mkuwa amalowetsa amatsogolera , kuyika kosavuta kwa IGBT;

3. Kukana voteji mkulu, otsika tgδ, kutentha otsika kukwera;

4. ESL yochepa ndi ESR;

5. Kuthamanga kwakukulu Pakalipano.

Zithunzi za SMJ-P

Mu ntchito zamagetsi zamagetsi, snubber capacitor imalumikizidwa ndi node yayikulu-yomwe ikusintha ndicholinga chochepetsera ma parasitic inductance ya waya wamagetsi.

Parasitic inductance imayambitsa kuthamanga kwakukulu pakuzimitsa (pamene magetsi atsekedwa), ndipo ngati mawotchi oterowo angapitirire chiwerengero cha zigawo, pali nkhawa za kulephera koipitsitsa.

Pogwiritsa ntchito zomangira zamkati zotsika, zomangira zopangira utomoni, ndikuzimitsa makonda, SMJ-P Series idapangidwa kuti isinthe mwachangu IGBTS ndipo imatha kukhala ngati zosefera komanso zosefera zaposachedwa kwambiri.
