Abstract

L'invention concerne un amplificateur de puissance à découpage comportant une unité de génération de signal de modulation de largeur d'impulsion (PWM) qui convertit un signal audio en entrée en un signal PWM présentant une fréquence de porteuse prédéterminée, une unité de correction qui corrige la différence entre le signal audio inclus dans le signal PWM et un signal audio en sortie de contre réaction afin de générer un signal PWM corrigé, un filtre passe bas qui supprime une composante à haute fréquence du signal PWM corrigé, une unité de modulation de fréquence qui module le signal PWM corrigé de telle sorte que le signal PWM corrigé présente une fréquence de commutation différente de la fréquence de la porteuse du signal PWM en entrée afin de générer un signal PWM modulé, ainsi qu'une unité d'amplification de puissance qui amplifie la puissance du signal PWM modulé.
