Measuring Switch-Mode Power Amplifiers

Oct. 11, 2024
Discover the evolution of audio amplification as Class D switch-mode amplifiers challenge traditional Class A designs. This study reveals the complexities of measuring performance and the vital role of passive filters for achieving accurate results.

This paper explores the rise of Class D switch-mode audio amplifiers, which have overtaken Class A linear amplifiers in consumer electronics due to their compact size, light weight, and enhanced efficiency. Despite their advantages, measuring the performance of these amplifiers poses challenges due to inherent ultrasonic artifacts. This paper outlines necessary methodologies for accurate measurements and highlights the importance of external passive filters in mitigating non-linear behavior.
