Abstract

La présente invention permet d'assurer une commande de puissance à haut rendement d'un amplificateur de puissance (p. ex. de limitation d'amplitude à niveau constant ou à mode de commutation) à haut rendement. On réduit l'écart entre une fréquence maximale de modulation voulue et la fréquence de fonctionnement d'un convertisseur à mode de commutation continu-continu en faisant suivre le convertisseur à mode de commutation par un régulateur linéaire actif. Le régulateur linéaire commande la tension de fonctionnement de l'amplificateur de puissance à l'aide d'une bande passante suffisante pour reproduire la forme d'onde de modulation d'amplitude voulue. Le régulateur linéaire rejette les variations de sa tension d'entrée même si la tension de sortie change en réponse à un signal de commande appliqué. On obtient une modulation d'amplitude en faisant varier la tension de fonctionnement de l'amplificateur de puissance. On accroît le rendement élevé en permettant également au convertisseur à mode de commutation continu-continu de varier sa tension de sortie, de sorte que la chute de tension au régulateur linéaire est maintenue à un niveau faible et relativement constant.
