| Abstract: | Basic principle of PWM selective harmonic based on neural network is introduced, and a calculating method on pulse switching angle based on BP method of feed - forward network is presented in this paper. At the same time, the result of MATLAB is given, it indicates that this kind of method can be exactly realized to eliminate the harmonics and it can overcome the shortcoming that in the past using Newton iterative ways need to know the derivative of original equation, and it makes that the process of calculating is more compact and veracious. |
