V rezonan\u010dn\u00edch obvodech snubberu hraje kondenz\u00e1tor kl\u00ed\u010dovou roli p\u0159i vytv\u00e1\u0159en\u00ed rezonan\u010dn\u00edho obvodu n\u00e1dr\u017ee s parazitn\u00ed induk\u010dnost\u00ed p\u0159\u00edtomnou v syst\u00e9mu.<\/p>\n

Jak funguje rezonan\u010dn\u00ed obvod Snubber Capacitor:<\/strong><\/h3>\n

  • Rezonance:<\/strong> Kondenz\u00e1tor a parazitn\u00ed induk\u010dnost tvo\u0159\u00ed obvod LC n\u00e1dr\u017ee. Kdy\u017e se IGBT vypne, energie ulo\u017een\u00e1 v parazitn\u00ed induk\u010dnosti se p\u0159enese do kondenz\u00e1toru. K tomuto p\u0159enosu energie doch\u00e1z\u00ed p\u0159i rezonan\u010dn\u00ed frekvenci LC n\u00e1dr\u017ee, co\u017e vede k oscilac\u00edm.<\/li>\n
  • Rozptyl energie:<\/strong> V rezonan\u010dn\u00edm obvodu snubberu je obvykle za\u0159azen rezistor, kter\u00fd tlum\u00ed tyto oscilace a odv\u00e1d\u00ed energii.<\/li>\n<\/ul>\n
