Критичен анализ на линейни аудио усилватели – клас AB срещу клас H

Abstract

The point of this article is a critical analyses of the linear high efficiency audio amplifier. This type of amplifier is a combination of the above two types which provides an acceptable level of THD performance (typically 0.1% to 1% distortion [2]) at similar output efficiency. Of this kind audio amplifier we both output devices are allowed to conduct at the same time, but just a small amount near the crossover point. This structure allowed the efficiency and reduces THD of the output signal.
