Abstract

La présente invention concerne un dispositif de conversion de puissance dans lequel la fluctuation d'une tension de sortie est faible même si un courant de charge change brusquement. Le dispositif de conversion de puissance (50) est pourvu : d'une unité de circuit principal comprenant des éléments de commutation ; d'une unité de commande de tension (11) pour générer une valeur d'instruction de courant sur la base de l'écart de tension entre une valeur d'instruction de tension et une valeur de détection de tension ; et d'une unité de commande de courant (12) pour commander les éléments de commutation sur la base de l'écart de courant entre une valeur d'instruction de courant et une valeur de détection de courant. Le dispositif de conversion de puissance (50) est également pourvu d'une unité de correction de valeur d'instruction de courant (10) pour corriger la valeur d'instruction de courant sur la base de l'écart de tension et de l'écart de courant.
