Practical Implementation and Error Analysis of PSCPWM-Based Switching Audio Power Amplifiers

In 107th Audio Engineering Society Convention — 1999

By Christensen, Frank Schwartz1; Frederiksen, Thomas Mansachs1; Andersen, Michael Andreas E.1; Nielsen, Karsten1

From

Department of Applied Electronics, Technical University of Denmark1

The paper presents an in-depth analysis of practical results for Parallel Phase-Shifted Carrier Pulse-Width Modulation (PSCPWM) - amplifier. Spectral analyses of error sources involved in PSCPWM are presented. The analysis is performed both by numerical means in MATLAB and by simulation in PSPICE, followed by practical verification on a prototype.

A toolbox for MATLAB has been developed to ease the complex analysis.
