| Abstract: | The purpose of this paper is to analyse the harmonic in PWM waveform by means of experiment and theory computation. Therefore, we know that the harmonic in PWM waveform can not be eliminated, and then we can remove the most harmful harmonic to optimize PWM waveform. This is vital to inverter circuit and motor design. |
