Harmonic Analysis of PWM Rectifier Based on Space Voltage Vector
摘要
Abstract
To analyze the harmonic characteristics of PWM rectifier quantificationally, on the basis of analyzing the principle of math model of PWM rectifier, the analytical expressions of harmonics voltage and current on power network side are given by Fourier analysis firstly. Then, Harmonic characteristics of voltage and current on power network side are analyzed with different parameters, and the mutative principle of amplitude and content of each harmonic with the variation of modulation parameters are presented also. The presented harmonic calculation method is verified by simulation, and harmonic spectrums of current on power network side with different inductance values are presented. Simulation results have verified the validity of the presented algorithm.关键词
