V rezonan\u010dn\u00fdch obvodoch snubberu zohr\u00e1va kondenz\u00e1tor k\u013e\u00fa\u010dov\u00fa \u00falohu pri vytv\u00e1ran\u00ed rezonan\u010dn\u00e9ho obvodu n\u00e1dr\u017ee s parazitnou induk\u010dnos\u0165ou pr\u00edtomnou v syst\u00e9me.<\/p>\n

Ako funguje rezonan\u010dn\u00fd kondenz\u00e1tor Snubber:<\/strong><\/h3>\n
    \n
  • Rezonancia:<\/strong> Kondenz\u00e1tor a parazitn\u00e1 induk\u010dnos\u0165 tvoria LC obvod n\u00e1dr\u017ee. Ke\u010f sa IGBT vypne, energia ulo\u017een\u00e1 v parazitnej induk\u010dnosti sa prenesie do kondenz\u00e1tora. Tento prenos energie sa uskuto\u010d\u0148uje pri rezonan\u010dnej frekvencii LC n\u00e1dr\u017ee, \u010do vedie k oscil\u00e1ci\u00e1m.<\/li>\n
  • Rozptyl energie:<\/strong> Do rezonan\u010dn\u00e9ho obvodu snubberu sa zvy\u010dajne zara\u010fuje rezistor, ktor\u00fd tlm\u00ed tieto oscil\u00e1cie a rozpty\u013euje energiu.<\/li>\n<\/ul>\n
