Abstract
An audio amplifier which combines the advantages of analogue and digit al amplifiers is proposed. The high fidelity of an analogue amplifier and high efficiency of a digital amplifier are simultaneously achieved in one system. Experimental results show that the proposed amplifier has 0.005% total harmonic distortion and 90% power efficiency at outpu t = 50 W.
