Audio power amplifier |
| 摘要 |
<p>An audio power amplifier achieved with a hybrid architecture constituted by the magnetic coupling of a linear amplifier (Hd lin ) with a switching amplifier (Hd SW ) placed on two coaxial coils of a loudspeaker (LS1), or with a hybrid architecture constituted by the electrical coupling of a linear amplifier (Hd lin ) with a switching amplifier (Hd SW ). These solutions allow obtaining an amplifier characterized by the low distortion of a linear amplifier and by the high efficiency of the switching amplifier.</p> |
