Abstract

La présente invention concerne un circuit de source d'alimentation de commutateur pour un chargeur monté sur un véhicule intégré et un convertisseur. Le circuit comprend un circuit d'entrée, un transformateur et un circuit secondaire, le circuit d'entrée comprenant un premier circuit d'entrée d'enroulement et un second circuit d'entrée d'enroulement ; le transformateur comprend un premier enroulement primaire, un second enroulement primaire, un enroulement secondaire et un noyau de fer ; le premier circuit d'entrée d'enroulement est connecté au premier enroulement primaire ; le second circuit d'entrée d'enroulement est connecté au second enroulement primaire ; l'enroulement secondaire est connecté au circuit secondaire ; le premier circuit d'entrée d'enroulement et le second circuit d'entrée d'enroulement sont connectés en série ; un signal haute tension génère un premier signal électrique et un second signal électrique au moyen du premier circuit d'entrée d'enroulement et du second circuit d'entrée d'enroulement ; le premier signal électrique et le second signal électrique génèrent un premier flux magnétique et un deuxième flux magnétique au moyen du premier enroulement primaire et du second enroulement primaire ; et le premier flux magnétique et le deuxième flux magnétique sont superposés afin de générer un troisième flux magnétique et de générer ensuite un signal basse tension au moyen de l'enroulement secondaire. La présente invention peut agrandir la plage d'adaptation d'une tension d'entrée d'un circuit.
