The paper presents a fundamental analysis of modulation schemes and their spectral aspects for a range of power stage topologies, from a simple 2-level switching leg to more complex multi-level switching topologies. A family of modulation schemes is introduced and the double Fourier series based analysis leads to a redefinition of pulse width modulation including amplitude modulation. A GUI-based simulation toolbox for MATLAB1 - PWMSIM - has been developed to ease the design of optimized modulator structures for any application.
