Much has been written about the efficiency of Class D amplifiers, with figures of 90 percent or greater being routinely quoted. Such numbers might seem to suggest that the efficiency problem of audio amplifiers has been well-solved by conventional Class D. However, a closer look shows that this is far from the truth, with these amplifiers frequently seeing only single-digit percentage efficiencies, in real product usage conditions.
