Abstract: Sinusoidal voltage waveform in synchronous generators is of great significance in power systems. Generally speaking, the output voltage of a synchronous generator issemi-sinusoidal including some disturbance frequencies (known as harmonics) rather than the fundamental frequency. The harmonic contents cause them to increase in iron
