Title
(EN) METHODS AND SYSTEMS FOR COMPONENT VALUE ESTIMATION IN POWER SUPPLIES/CONVERTERS
(FR) PROCÉDÉS ET SYSTÈMES POUR L'ESTIMATION DE VALEUR DE COMPOSANT DANS DES ALIMENTATIONS ÉLECTRIQUES/CONVERTISSEURS
Abstract
(EN)
In one embodiment, the method of these teachings includes decomposing the output ripple voltage into its constituent components and utilizing the scale factor necessary for this decomposition to obtain the measure capacitance and ESR for a power supply/converter.
(FR)
Selon un mode de réalisation, la présente invention porte sur un procédé comprenant la décomposition d'une tension d'ondulation de sortie en ses composants constitutifs et l'utilisation du facteur d'échelle nécessaire pour cette décomposition pour obtenir la capacité de mesure et la résistance série équivalente pour une alimentation électrique/convertisseur.
