Abstract

Abstract Translated from French Dispositif amplificateur pour audio-fréquences comportant un premier amplificateur (41) en classe B, un second amplificateur (42) en classe B, des moyens de commutation (50) commandés par un sous-ensemble de commande (55), et des moyens de transmission (60) appliquant un signal à l'entrée de l'amplificateur (42). La charge est alors connectée au premier amplificateur (41), et au moyen de commutation (50) la reliant soit à la sortie du second amplificateur (42), soit à un point milieu de potentiel zéro (53). Application à la réalisation d'un amplificateur pour audio-fréquences en classe G ne comportant qu'une seule source d'alimentation. Amplifier device for audio-frequencies comprising a first amplifier (41) in class B, a second amplifier (42) in class B, switching means (50) controlled by a control sub-assembly (55), and means for transmission (60) applying a signal to the input of the amplifier (42). The load is then connected to the first amplifier (41), and to the switching means (50) connecting it either to the output of the second amplifier (42), or to a midpoint of zero potential (53). Application to the production of an amplifier for audio-frequencies in class G comprising only one power source.
