Reduce Harmonic Distortion using Pseudorandom PWM Technique
Abstract: Due to harmonic content in the voltage and current wave forms in the power electronic devices working at high frequencies cause mechanical vibrations, acoustic noise, and EMI interference makes the workers uncomfortable. Proposed work deals with a new and effective technique to possess low acoustic noise and mechanical vibration when lower switching frequency is chosen. Pseudo random pulse width modulation the new established technique is used to eliminate this undesirable …

Development of Random Pulse Width Modulation in Power Electronics Converter
Abstract: With the new advancement in power electronic devices the high frequency system can often causes acoustic noise, mechanical vibration, EMI related problems in inverter-fed AC machine due to harmonics content in voltage and current waveforms which makes operator feel uncomfortable to work. Proposed work deals with one of the Pulse Modulation Technique, Random Pulse Width Modulation (RPWM), which is a new and effective technique to let the inverter-fed ac motor …
