Abstract
(EN)
The purpose of the present invention is to provide a power converter that, even over wide input voltage ranges and output current ranges, is low in cost, high in efficiency, and is capable of voltage conversion so as to correspond to rapid load variations. The power converter is provided with: a non-insulation type step-up/step-down converter circuit (15) that steps an input voltage up or down and outputs a direct-current voltage; an insulation type converter circuit (16) that accepts input of the direct-current voltage outputted from the non-insulation type step-up/step-down converter circuit (15) and outputs a direct-current voltage to a load; and a control unit (17) that controls the non-insulation type step-up/step-down converter circuit (15) and the insulation type converter circuit (16). The control unit (17) controls the step-up/step-down ratio between the inputted voltage and an output voltage Vo of the insulation type converter circuit (16) by using the non-insulation type step-up/step-down circuit (15) only, and thereby adjusts the output voltage Vo so as to achieve a target value.

L'objet de la présente invention est de fournir un convertisseur de puissance qui, même sur de larges plages de tension d'entrée et de larges plages de courant de sortie, a un coût réduit, un rendement élevé, et est capable d'effectuer une conversion de tension de manière à correspondre à de rapides variations de charge. Le convertisseur de puissance est pourvu : d'un circuit convertisseur élévateur/abaisseur de type non isolant (15) qui élève ou abaisse une tension d'entrée et délivre en sortie une tension continue ; d'un circuit convertisseur de type isolant (16) qui accepte l'entrée de la tension continue délivrée en sortie par le circuit convertisseur élévateur/abaisseur de type non isolant (15) et délivre en sortie une tension continue à une charge ; et d'une unité de commande (17) qui commande le circuit convertisseur élévateur/abaisseur de type non isolant (15) et le circuit convertisseur de type isolant (16). L'unité de commande (17) commande le rapport d'élévation/d'abaissement entre la tension d'entrée et une tension de sortie Vo du circuit convertisseur de type isolant (16) en utilisant le circuit convertisseur élévateur/abaisseur de type non isolant (15) uniquement, et ajuste ainsi la tension de sortie Vo de manière à obtenir une valeur cible.
