Abstract

This research aims to compare the effects of efficiency and distortion in Audio Power Amplifiers with and without Tracking Power Supply (TPS) circuit design. The TPS circuit design is known for enhancing power efficiency while keeping low distortion in the amplifiers. This paper examined the performance of Class-A type Audio Power Amplifiers with and without a TPS circuit. The performances are evaluated for power efficiency and distortion levels using standard tools and procedures. The results show the amplifier with a TPS circuit design exhibits significantly higher power efficiency than one without a TPS. The TPS in the Audio Power Amplifier will increase the power efficiency from 34% to 51 % for the Class-A type. Moreover, the TPS implementation demonstrates the little effect on the total harmonic distortion (THD) of the 20 W amplifier to an 8 Ω load with THD 0.0027% at a 1 kHz audio operating frequency. These findings highlight the potential of TPS circuit design in improving efficiency with low distortion characteristics on the Audio Power Amplifiers.
