摘要
This study presents an analysis of five-phase voltage source inverter with dual frequency modulator to reduce baseband harmonics distortion. Analyses of five-phase inverter load equation, error signal, system stability and states bounds are carried out. Further, the frequency domain analysis shows the noise shaping effect of the proposed dual frequency modulator. Three design examples with first, second and forth order dual frequency modulators are shown. Both simulations and experiments are illustrated, telling that the proposed modulator can reduce baseband harmonics distortion as discussed in the frequency domain analysis. Further, the states bounds obtained from simulations agree with the theoretical value, showing the correctness of the analysis. Both simulations and experiments correspond to each other, confirming the effectiveness of the proposed five-phase inverter driven by dual frequency modulator.
