Da farko, bari muyi magana game da ainihin ƙa'idar aiki na BOOST circuit: A cikin hoton da ke ƙasa, MOS transistor shine sauyawa.Muddin saurin yana da sauri sosai (yawan sauyawa ya isa sosai), lokacin kunnawa da kashewa (lokacin caji da lokacin caji) ana sarrafa shi sosai, kuma an haɗa shi da capacitor na fitarwa, ana iya samun ingantaccen Vo (muryar). irin ƙarfin lantarki na mu masu hankaliONUshine gabaɗaya 48V), wanda shine ƙarfin fitarwa.
Lokacin da mai kunnawa ya kunna, inductor L yana ƙasa, an yanke diode, kuma Vi yana cajin inductor L.
