ACOUSTIC NOISE REDUCTION IN THE SWITCHED RELUCTANCE MOTOR USING THE PULSE-WIDTH MODULATION WITH THE RANDOM SWITCHING STRATEGY

Considers algorithm of pulse-width modulation PWM with a random switching strategy to reduce the harmonics spectra of the phase voltage, to reduce the vibration and acoustic noise for switched reluctance motor (SRM). Similar technique is useful for induction motors to reduce acoustic noise. The proposed method combines random turn-on, turn-off angle technique and random pulse-width modulation technique. In order to confirm the effectiveness of the algorithm an experiment (computer simulation) was conducted.
