Abstract
A general method is considered for optimizing the output waveform of pulsewidth-modulated (PWM) inverters, whatever load may be supplied. It consists of the minimization of a cost function of operation of the load fed by the inverter. The mathematical tools and the numerical techniques to calculate the optimum switching patterns in the space of PWM inputs are derived using the state variable description of the dynamics of the system. Nonlinear state equations are assumed. Some examples and comparisons are included to show the features of the proposed PWM methods.Keywords
