THD Improvement of a PWM Cascade Multilevel Power Inverters Using Genetic Algorithms as Optimization Method
Authors: , ,
Abstract: This paper presents an optimization of the electric power quality by designing a 9 steps multilevel power inverter, which adopts a multi-PWM optimized using genetic algorithms (GA), and minimizing Total Harmonic Distortion (THD) of the first 50 harmonics to about 0%. This optimization is considered an alternative technique because it reduces the expression used to quantify TDH numerically. Particularly for the 9 steps multilevel wave form, it reduces the number of power on-and-off angles as well as the position within the levels of the first quarter-wave modulation. The research involved developing a prototype for experimental verification.
