AB  - A novel high-efficiency power amplifier topology for audio reproduction is presented. The topology breaks previous performance barriers in switching technology by combining an effective error-correction method, Multivariable Enhanced Cascade Control (MECC), with a new integrated modulator topology, Controlled Oscillation Modulation (COM). This topological combination proved to be very elegant. Extensive measurements are given on 250-W, 500-W, and 1000-W case implementations of the MECC/COM topology, showing, e.g., 0.0005% (-106-dB) true THD combined with state-of-the-art power and volume efficiency.:
