On specific harmonic elimination PWM of inverter based on genetic algorithm

In order to solve the problem of switching angle of a specific harmonic elimination inverter, a genetic algorithm is proposed to solve the problem of the nonlinear transcendental equation. This method overcomes the shortcoming of traditional numerical method, and does not need to give the initial value of the equation. It mainly uses the idea of solving the objective function minimum, combined with the characteristics of the genetic algorithm, and makes the algorithm obtain higher convergence speed and precision. The simulation study of the harmonic elimination model is carried out with the Matlab simulation software. The experimental results show that the method has high accuracy and convergence.
