Abstract :
In this paper, the results relative to switched reluctance machine (SRM) acoustic noise are presented. The authors have particularly concentrated on the influence of power supply. Vibrations and radiated acoustic pressure have been reduced thanks to the flux instantaneous variation control, which was applied in limiting the duty cycle variations. Adding a simple electronic block inside the control unit enables, at any instant in time, to carry out this function of controlling the flux gradient. In order to quantify the contribution provided by this method, they have determined, by means of simulations and experimental measurements, the acoustic pressure levels as well as the performances of the machine
