Voltage harmonic elimination of PWM AC chopper using Artificial Neural Network

A voltage harmonic elimination method in a Puls Width Modulated (PWM) AC chopper using Artificial Neural Network (ANN) is proposed. The formulation of the harmonic elimination problem and the application of ANN on this problem is discussed. The output voltage is written using Fourier series in terms of switching angle with k pulses per half cycle.
