In this paper a hybrid architecture is presented, that combines linear and switching topology, in order to obtain an audio amplifier featuring high efficiency, low distortion and high bandwidth. The intrinsic structure of the switching stage allows an automatic spreading of the switching frequency, reducing EMI issues. A prototype amplifier was realized, tailored for automotive applications. The proposed architecture is patent pending.
