A Chaotic Carrier Frequency SVPWM Strategy to Reduce the Harmonic Distortion

Abstract:

Harmonics always have a negative impact on control precision and grid quality. It has been found out that harmonic distribution is very germane to carrier frequency. Based on the analysis of conventional SVPWM, in this paper a chaotic carrier frequency SVPWM strategy is proposed, where the theory of chaos is applied to generate the desired random source for SVPWM carrier frequency. Simulation result proves that chaotic carrier frequency SVPWM can not only improve the waveform quality, reduce the low-order harmonics, and also flatten the high-order harmonics effectively.
