Komutacinis maitinimo kondensatorius \"Snubber<\/h3>\n<\/div>\n<\/div>\n
Komutuojamuosiuose maitinimo \u0161altiniuose snubberio kondensatoriai yra labai svarb\u016bs siekiant apsaugoti komutuojamuosius \u012ftaisus (pvz., MOSFET arba IGBT) nuo per didel\u0117s \u012ftampos ir srov\u0117s apkrovos perjungimo metu.<\/span>\u00a0 \u00a0<\/span><\/div>\n<\/div>\n
