The simulation research for selective harmonic elimination technique based on genetic algorithm

Using the genetic algorithm to solve the selective harmonic elimination technology optimization method, which can be arbitrary for the choice of initial value, make up for the deficiency of the Newton iterative algorithm, in the absence of specific initial conditions can complete the calculation, therefore there is no need predict the tendency of switch angles in the entire modulation range in advance. Modeling and simulation by Matlab/Simulink, according to the different load of selective harmonic elimination technology perform simulation study, and when the size of the load change to put forward the method of increasing the switching angles to improve the harm of harmonic.
