Abstract
- This paper proposed a novel hybrid random pulsewidth modulation (HRPWM) technique based on the modified space vector PWM for three-phase voltage source inverters to eliminate the PWM acoustic noise. Due to PWM technique and switching losses considerations, ear-piercing high-frequency noise from motor is common. The proposed HRPWM technique is able to remove the high-frequency unpleasant acoustic noise more effectively than the conventional RPWM with lower switching losses and shorter random frequency range. In addition, the PWM harmonics in phase voltage and phase current are reduced significantly. The HRPWM method is simple to implement and does not employ additional circuits in drive system. Finally, the effectiveness of the proposed approach has been confirmed by detailed experimental results. [ABSTRACT FROM AUTHOR]
