Title (EN) VOLTAGE CONTROL IN A CONVERTER SUPPLYING POWER TO A LOAD
(FR) RÉGULATION DE TENSION DANS UN CONVERTISSEUR ALIMENTANT ÉLECTRIQUEMENT UNE CHARGE
Abstract:
(EN) The invention relates to a converter control device, method, computer program and computer program product for controlling power supply by a converter to a load. The power supply device (22) comprises a converter control unit (34), which obtains a measure (Vint) of the load voltage (VL1) as a voltage at the converter (30), obtains an estimate of a voltage drop (VD) between the converter (30) and the load (L1), obtains a reference voltage (Vref) corresponding to a desired load voltage, adjusts either the reference voltage (Vref) or the load voltage measure (Vint) with the voltage of the estimated voltage drop (VD), compares, after the adjustment, the load voltage measure (Vint) with the reference voltage (Vref) for obtaining an error signal (VE), and controls the converter (30) to provide the load voltage (VL1) based on the error signal (VE).
(FR) L'invention concerne un dispositif, un procédé, un programme informatique et un produit programme informatique de commande de convertisseur destinés à commander l'alimentation électrique d'une charge par un convertisseur. Un dispositif d'alimentation électrique (22) comprend une unité de commande de convertisseur (34), qui obtient une mesure (Vint) de la tension de charge (VL1) sous la forme d'une tension au niveau du convertisseur (30), obtient une estimation d'une chute de tension (VD) entre le convertisseur (30) et la charge (L1), obtient une tension de référence (Vref) correspondant à une tension de charge souhaitée, ajuste soit la tension de référence (Vref) soit la mesure de tension de charge (Vint) avec la tension de la chute de tension estimée (VD), compare, après le réglage, la mesure de tension de charge (Vint) à la tension de référence (Vref) pour obtenir un signal d'erreur (VE), et commande le convertisseur (30) pour fournir la tension de charge (VL1) sur la base du signal d'erreur (VE).
