Abstract :
Results of two interrelated studies devoted to assessment of mitigating effects of random pulse width modulation on the electromagnetic and acoustic noise generated in vehicular AC drives are presented. Computer simulations and experimental investigation have demonstrated that the random modulation, especially its technically convenient RPWM II version, significantly reduces both types of the noise. Therefore, it can be used as an effective and inexpensive tool for meeting the respective engineering standards.
