| titleOfInvention | Device and method for driving an electric machine for abating and masking distinctive acoustic emissions |
| abstract | A device (11) for driving an electric motor (18), comprising: an inverter circuit (14), configured for converting a d.c. supply signal (V AL ) into an a.c. supply signal (Va, Vb, Vc); and a control block (13), connected to the inverter circuit (14) and configured for controlling the inverter circuit (14) by means of a pulse-width modulation (PWM), having a given cycle- period value. The driving device further comprises a first random-number generator (15), connected to the control block (13) and configured for supplying to the control block (13) pseudo-random or random cycle-period values (T VAR ). |
