Title (EN) METHOD OF ESTIMATING AN OPERATING CHARACTERISTIC OF A POWER CONVERTER
(FR) PROCÉDÉ D'ESTIMATION D'UNE CARACTÉRISTIQUE DE FONCTIONNEMENT D'UN CONVERTISSEUR DE PUISSANCE
Abstract:
(EN) A system and method of estimating an operating characteristic of a power converter including a power switch. In an embodiment, the method includes generating a duty cycle to control the power switch to control an output characteristic of the power converter. The method also includes producing an estimate of an output current of the power converter employing the duty cycle and an input voltage of the power converter.
(FR) L'invention concerne un système et un procédé d'estimation d'une caractéristique de fonctionnement d'un convertisseur de puissance comprenant un commutateur de puissance. Dans un mode de réalisation, le procédé consiste à générer un rapport cyclique pour commander le commutateur de puissance afin de commander une caractéristique de sortie du convertisseur de puissance. Le procédé consiste également à produire une estimation d'un courant de sortie du convertisseur de puissance à l'aide du rapport cyclique et d'une tension d'entrée du convertisseur de puissance.
