FAQ:
Q: Quels sont les avantages d’un amplificateur hifi de classe B?
A: Alors que toutes les connexions de sortie d’un amplificateur de classe A conduisent une charge 100% du temps, les amplis hifi de classe B utilisent un agencement push & pull de telle sorte que seulement la moitié des appareils de sortie sont conducteurs à un moment donné.
Q: Qu’est-ce que la classe d’un amplificateur audio?
A: La classe d’un amplificateur audio caractérise le fonctionnement électrique de l’étage de sortie de cet ampli. Un ampli audio peut être choisi pour différents besoins : puissance de sortie, rendement, distorsion, bande passante, prix, etc… Ampli audio hifi : quelle classe de fonctionnement ?
Q: Quels sont les différents types d’amplificateurs dans l’audio domestique?
A: Les classes d’amplificateurs les plus courantes dans l’audio domestique sont les classes A, A/B, D, G et H. Ces classes ne sont pas de simples systèmes de notation, mais des descriptions de la topologie de l’amplificateur, c’est-à-dire comment ils fonctionnent à un niveau de base.
Q: Quel est le mode de fonctionnement d’un amplificateur de classe d?
A: Ce mode de fonctionnement est illustré dans le schéma fonctionnel de la Figure 2, où une contre-réaction est dérivée de l’entrée du filtre. L’avantage clé d’un amplificateur de classe D est son très haut rendement, qui s’élève à environ 90 %.
