Kapasitera IGBT Snubber sarimihetsika metaly

Famaritana fohy:

1. Boaty plastika, voaisy tombo-kase amin'ny resin;

2. Tariby varahina vita amin'ny firapotsy, mora apetraka ho an'ny IGBT;

3. Fanoherana ny voltase avo lenta, tgδ ambany, fiakaran'ny mari-pana ambany;

4. ESL sy ESR ambany;

5. Fikorianan'ny herinaratra avo lenta.

Andian-dahatsoratra SMJ-P

Amin'ny fampiharana elektronika herinaratra, ny kapasitera snubber dia mifandray amin'ny node switching misy courant lehibe mba hampihenana ny inductance parasitika amin'ny tariby elektrika.

Ny inductance katsentsitra dia miteraka fiakarana lehibe rehefa vonoina ny herinaratra (rehefa voasakana ny courant), ary raha mihoatra ny naotin'ny singa izany fiakarana izany, dia misy ny ahiahy momba ny tsy fahombiazana raha sendra tranga ratsy indrindra.

Amin'ny fampiasana rafitra anatiny misy inductance ambany, boaty resin vita amin'ny lasitra azo isafidianana, ary terminal namboarina manokana, ny andiany SMJ-P dia natao ho an'ny IGBTS mifamadika haingana ary afaka miasa ho toy ny snubbers sy sivana fidirana matetika avo lenta.
