The Application of Genetic Algorithms in Electrical Drives to Optimize the PWM Modulation

This paper describes a new strategy for pulsewidth modulation (PWM) optimized by a direct method and the application of genetic algorithms (GA) to minimize the harmonic content specifically the fifth and seventh harmonic of the total content, based on the minimum total harmonic distortion (THD). Described the development of the method, the guidelines to take into account including the algorithm development, the strategy within the Digital Signal Processor (DSP), and the obtained results can be visualized.
