Influence on Output Voltage Harmonic with Switching Frequency and Modulation Voltage Amplitude of SVPWM Inverter
The paper introduces the inverter which based on the way of space-vector pulse width modulation (SVPWM).Using two dimensions Fourier progression tool,a kind of decomposition solution is adopted to analyze output voltage harmonic.Both the switching frequency and the modulation voltage amplitude have a certain effect on harmonic content.The influence to the THD is small by the switching frequency,but when the switching frequency changes,the distribution of harmonic content changes obviously.The influence to the THD is large by the modulation voltage amplitude,when the modulation voltage amplitude changes more,the THD changes lower.At last,the SVPWM inverter is simulated by Simulink in MATLAB and the simulation waveform of the output voltage is also given.The simulation results confirm the validity of the analyses.
