摘要

综述了随机脉宽调制(RPWM)理论和实践的最新进展。涵盖的主题包括RPWM的原理、随机化的手段、现有RPWM技术的回顾、功率谱、实施问题以及RPWM对电力驱动系统的文献影响。许多RWPM策略已经被报道，并且对声学噪声和振动的有益影响已经得到一致同意。已发表的研究证明，与传统的确定性PWM策略相比，电机的声学噪声特性可以在几乎没有额外费用的情况下得到显著改善。

Random pulse width modulation techniques for converter fed drive systems-a review

A review of the state of the art in RPWM (random pulse width modulation) theory and practice is presented. Topics covered include principles of RPWM, means of randomization, a review of the existing RPWM techniques, power spectra, implementation issues, and documented effects of RPWM on electric drive systems. A number of RWPM strategies have been reported, and a beneficial impact on acoustic noise and vibration has been unamiously agreed upon. Published studies have proven that significant improvement of the acoustic noise characteristics of the motors can be achieved at practically no extra expense in comparison with the systems with traditional, deterministic PWM strategies.<>
