A new method is presented or selective harmonic elimination in pulse-width (PWM) inverter waveforms by the novel use of Walsh functions. The Walsh operational matrix of pulse-width modulation (WOM-PWM) is introduced as a means of obtaining the Walsh spectral equations of PWM waveforms. The slope and intercept Fourier operational matrices of pulse-width modulation (SFOM-PWM and IFOM-PWM) are also introduced as a means of obtaining Fourier spectral equations of PWM waveforms.
