Abstract
This paper proposes a random pulse width modulation scheme, where the frequency of the triangular waveform is generated in a random way, for decreasing the acoustic noise of an induction motor. Two different strategies have been implemented: generation of a triangular waveform with randomized frequency for each fixed subcycle and for each random subcycle of the output frequency
