Description
Summary:In this digest, asymmetric sinusoidal inverter (ASI) output distortion is analyzed. Based on the spectral analysis of the asymmetric sinusoidal waveform, the influence of the output filter and digital control of the asymmetric sinusoidal inverter is analyzed. Through the method of double Fourier transform, the accurate spectral component expression of dead time waveform is obtained, and the influence of dead time waveform on output distortion is analyzed. The results provide a theoretical basis for suppressing the output voltage waveform distortion of this kind of power supply. Finally, the validity of the analysis is verified by simulation and experiment.
