AB  - The concepts and design aspects of all-digital open-loop audio power amplifiers, based on multi-level power converters, are presented. Innovative modulation techniques to reduce harmonic distortion of this type of amplifiers are also presented. A prototype of a digital multi-level audio power amplifier has been developed, implemented and tested. THD plus noise performance comparisons between some class A, AB and D amplifiers are presented. Results show that the proposed digital audio power amplifier can be a promising solution for high quality digital audio power amplifier.
