| Abstract: | A novel random space vector modulation technique based on small switch losses was proposed. This method based on SVM waveforms adoptted random change switch frequency and varying zero vector distribution, to reduce the switch losses and acoustic noise. The realization scheme based on the TMS320C24X DSP was presented. |
